Chapter 1, deciding on concerns in a Multisite Deployment
Deploying Cisco Unified Communications manager between assorted websites requires a suitable dial plan, applicable bandwidth, a top quality of carrier (QoS) implementation and a design that can survive IP WAN failures.
This chapter will clarify the concerns that may arise in a multisite Cisco UC supervisor deployment, and suggest specific solutions.

Multisite deployment problem overview
formerly referred to as Cisco name supervisor (CCM), Cisco Unified Communications supervisor (CUCM) multi-website deployment challenges can encompass the following:
IP networks had been not at the beginning designed to lift precise-time traffic; as a substitute, they had been designed for resiliency and fault tolerance. every packet is processed one after the other in an IP community, on occasion causing diverse packets in a communications circulation to take distinctive paths to the destination. The diverse paths within the network can also have a different amount of packet loss, prolong, and lengthen version (jitter) because of bandwidth, distance, and congestion ameliorations. The destination need to be able to receive packets out of order and resequence these packets. This problem is solved by way of precise-Time Transport Protocol (RTP) sequence numbers and traffic resequencing. When possible, it's choicest to not rely fully on these RTP mechanisms. proper community design, the use of Cisco router Cisco specific Forwarding (CEF) swap cache expertise, performs per-destination load sharing by way of default. Per-destination load sharing isn't an ideal load-balancing paradigm, but it surely ensures that each IP movement (voice name) takes the same route.
Bandwidth is shared via varied clients and functions, whereas the amount of bandwidth required for a person IP circulate varies enormously all through brief lapses of time. Most facts functions are very bursty, whereas Cisco precise-time audio communications with RTP use the equal continuous-bandwidth circulate. The bandwidth obtainable for any software, together with CUCM and voice-bearer traffic, is unpredictable. all over peak periods, packets need to be buffered in queues waiting to be processed on account of network congestion. Queuing is a term that anyone who has ever skilled air flight is regularly occurring with. if you happen to arrive on the airport, you must get in a line (queue), since the variety of ticket brokers (bandwidth) available to examine you in is below the circulation of site visitors arriving at the ticket counters (incoming IP traffic). If congestion happens for too long, the queue (packet buffers) receives crammed up, and passengers are irritated (packets are dropped). bigger queuing delays and packet drops are greater doubtless on extremely loaded, sluggish-velocity hyperlinks reminiscent of WAN hyperlinks used between websites in a multisite ambiance. best challenges are regular on these kinds of links, and you need to handle them by means of implementing QoS. with out the use of QoS, voice packets adventure lengthen, jitter, and packet loss, impacting voice great. it's essential to thoroughly configure Cisco QoS mechanisms conclusion to conclusion all through the network for proper audio and video efficiency.This chapter turned into excerpted with permissions from implementing Cisco Unified Communications manager, half 2, by Chris Olsen, Copyright 2008. For extra tips about this e-book and other titles, please seek advice from Cisco Press.
right through peak durations, packets can not be despatched automatically because of interface congestion. as an alternative, the packets are briefly kept in a queue, ready to be processed. The amount of time the packet waits in the queue, known as the queuing delay, can fluctuate significantly in accordance with community situations and site visitors arrival fees. If the queue is full, newly got packets can not be buffered anymore and get dropped (tail drop). determine 1-1 illustrates tail drop. Packets are processed on a primary in, first out (FIFO) model in the hardware queue of all router interfaces. Voice conversations are predictable and relentless (sampling is every 20 milliseconds with the aid of default), but statistics functions are bursty and grasping. Voice for this reason is subject to degradation of first-class as a result of delay, jitter, and packet loss.

every website in a multisite deployment usually is interconnected by using an IP WAN, or every now and then by a metropolitan-enviornment network (MAN) equivalent to Metro Ethernet. Bandwidth on WAN hyperlinks is restricted and comparatively costly. The aim is to make use of the accessible bandwidth as successfully as feasible. needless site visitors should still be faraway from the IP WAN hyperlinks through content filtering, firewalls, and access handle lists (ACL). IP WAN acceleration strategies for bandwidth optimization may still be regarded as well. Any length of congestion might influence in service degradation except QoS is deployed throughout the community.
Voice streams are constant and predictable for Cisco audio packets. customarily, the G.729 codec is used throughout the WAN to most reliable use bandwidth. As a comparison, the G.711 audio codec requires sixty four kbps, whereas packetizing the G.711 voice sample in an IP/UDP/RTP header each 20 ms requires 16 kbps plus the Layer 2 header overhead.
Voice is sampled every 20 ms, resulting in 50 packets per 2nd (pps). The IP header is 20 bytes, whereas the UDP header is eight bytes, and the RTP header is 12 bytes. The 40 bytes of header tips should be transformed to bits to figure out the packet price of the overhead. as a result of a byte has 8 bits, forty bytes * eight bits in a byte = 320 bits. The 320 bits are sent 50 instances per 2d in keeping with the 20-ms price (1 millisecond is 1/1000 of a second, and 20/one thousand = .02). So:
.02 * 50 = 1 second320 bits * 50 = 16,000 bits/sec, or sixteen kbps
Voice packets are benign compared to the bandwidth consumed by means of statistics functions. facts functions can fill the complete highest transmission unit (MTU) of an Ethernet body (1518 bytes or 9216 bytes if jumbo Ethernet frames had been enabled). In assessment to records application packets, voice packets are very small (60 bytes for G.729 and 200 bytes for G.711 with the default 20-ms sampling fee).
In figure 1-2, a conference bridge has been deployed on the leading web page. No convention bridge exists at the far off web site. If three IP telephones at a far off site be part of a conference, their RTP streams are despatched throughout the WAN to the convention bridge. The convention bridge, whether the usage of software or hardware materials, mixes the bought audio streams and then sends again three exciting unicast audio streams to the IP phones over the IP WAN. The convention bridge removes the receiver's voice from his or her interesting RTP move in order that the person doesn't adventure echo because of the lengthen of traversing the WAN link and mixing RTP audio streams within the conference bridge.

Centralized conference resources cause bandwidth, extend, and means challenges within the voice network. each G.711 RTP flow requires 80 kbps (plus the Layer 2 overhead), leading to 240 kbps of IP WAN bandwidth consumption by means of this voice conference. If the conference bridge have been not observed on the other facet of the IP WAN, this site visitors would no longer should traverse the WAN link, leading to less prolong and bandwidth consumption. If the faraway site had a CUCM vicinity configuration that resulted in calls with the G.729 codec back to the leading website, the application conferencing materials of CUCM would no longer be capable of mix the audio conversations. Hardware conferencing or hardware transcoder media materials in a voice gateway are required to accommodate G.729 audio conferencing. native hardware conference elements would eliminate this want. All centrally determined media components (music On grasp [MOH], annunciator, convention bridges, videoconferencing, and media termination points) undergo equivalent bandwidth, extend, and useful resource exhaustion challenges.
When deploying CUCM in multisite environments, centralized CUCM-based mostly services are accessed over the IP WAN. Affected services consist of here:
figure 1-3 shows a Unified Communications community during which the leading web page is connected to a far flung web site via a centralized name-processing atmosphere. The main website is also related to a far flung cluster via an intercluster trunk (ICT) representing a distributed name processing ambiance. The mixture of each centralized and distributed name processing represents a hybrid call-processing model by which small websites use the CUCM materials of the main website, however big remote workplaces have their personal CUCM cluster. On the bottom left of figure 1-three is a SIP trunk, usually over a Metro Ethernet connection to an online Telephony provider company (ITSP). The advantage of the SIP trunk is that the ITSP offers the gateways to the PSTN as an alternative of your featuring gateways at the leading web site.

An IP WAN outage in figure 1-3 will trigger an outage of name-processing services for the far flung web page linked in a centralized vogue. The far flung cluster will not suffer a name-processing outage, however the far flung cluster are usually not able to dial the leading web page over the IP WAN all over the outage. Mission-essential voice functions (voice mail, interactive voice response [IVR], and so forth) observed on the leading site might be unavailable to any of the other websites right through the WAN outage.
If the ITSP is the use of the equal links that allow IP WAN connectivity, all calls to and from the public switched telephone community (PSTN) will also be unavailable.
A deployment just like the one proven in determine 1-3 is considered badly designed as a result of the inability of IP WAN and PSTN backup.
Dial plan challenges
In a multisite deployment, with a single or multiple CUCM clusters, dial plan design requires the respect of a number of considerations that don't exist in single-web site deployments:
every interior directory number relates to a fixed-size PSTN number: in this case, every inside directory quantity has its own committed PSTN quantity. The listing quantity can, but doesn't need to, fit the least-colossal digits of the PSTN quantity. In international locations with a fixed numbering plan, such because the North American Numbering Plan (NANP), this continually means that the four-digit office codes are used as internal listing numbers. If these are not enjoyable, digits of workplace codes or administratively assigned web page codes should be would becould very well be brought, resulting in 5 or greater digits getting used for internal listing numbers.
an extra solution is to not reuse any digits of the PSTN number but to easily map each and every internally used listing quantity to any PSTN quantity assigned to the company. in this case, the interior and exterior numbers should not have the rest in general. If the internally used directory number matches the least-gigantic digits of its corresponding PSTN number, gigantic digits will also be set on the gateway or trunk. also, widespread external cellphone number masks, transformation masks, or prefixes can also be configured. here's true as a result of all internal listing numbers are changed to fully certified PSTN numbers within the identical means. an additional illustration is if the internal listing number is composed of parts of the PSTN number and administratively assigned digits equivalent to web page codes plus PSTN station codes, or distinct degrees, equivalent to PSTN station codes 4100 to 4180 that map to directory numbers 1100 to 1180, or absolutely independent mappings of inner listing numbers to PSTN numbers. if that's the case, one or more translation suggestions have to be used for incoming calls, and one or extra calling birthday party transformation guidelines, transformation masks, external phone quantity masks, or prefixes should be configured.
category of quantity (TON) in ISDN: The calling quantity (the automated quantity Identification [ANI]) of calls being acquired from the PSTN may also be represented in other ways:
- As a seven-digit subscriber quantity- As a ten-digit number, together with the area code- In foreign format with the country code in front of the area code
To standardize the ANI for all calls, the format this is used have to be prevalent, and the number must be modified consequently.
Overlapping and nonconsecutive numbers
In determine 1-four, Cisco IP phones at the main website use listing numbers 1001 to 1099, 2000 to 2157, and 2365 to 2999. at the far flung site, 1001 to 1099 and 2158 to 2364 are used. These listing numbers have two concerns. First, 1001 to 1099 overlap; these listing numbers exist at each websites, so they aren't exciting all over the comprehensive deployment. This motives an issue: If a consumer within the far flung web page dialed only the four digits 1001, which mobile would ring? This concern of overlapping dial plans has to be addressed with the aid of digit manipulation. additionally, the nonconsecutive use of the latitude 2000 to 2999 (with some reproduction numbers at the two sites) would require a significant variety of additional entries in name-routing tables since the ranges can rarely be summarized through one (or a couple of) entries.

mounted versus variable-length numbering plans
a hard and fast numbering plan points mounted-size area codes and native numbers. An open numbering plan points variance in length of area code or local quantity, or both, in the nation.
desk 1-1 contrasts the NANP and a variable-length numbering plan -- Germany's numbering plan in this illustration.
table 1-1element Description fastened Numbering Plan (NANP) Variable-length Numbering Plan (Germany) country code A code of one to 3 digits is used to attain the specific phone equipment for each and every nation or particular provider. achieve the E.164 commonplace from http://itu.org to peer all foreign country codes. 1 49 enviornment code Used within many international locations to route calls to a specific metropolis, region, or special service. depending on the nation or location, it might probably even be referred to as a numbering plan enviornment, subscriber trunk dialing code, country wide destination code, or routing code. Three digits Three to five digits Subscriber quantity Represents the selected cell number to be dialed, nevertheless it does not consist of the nation code, enviornment code (if applicable), foreign prefix, or trunk prefix. Three-digit trade code plus a 4-digit station code Three or more digits Trunk prefix The initial digits to be dialed in a home name, before the enviornment code and the subscriber number. 1 0 access code a host it really is historically dialed first "to get out to the PSTN," utilized in PBXs and VoIP methods. 90 international prefix The code dialed earlier than a global quantity (country code, area code if any, after which subscriber quantity). 011 00 or + (+ is used by means of cellphones)
The NANP PSTN number is 408-555-1234, DID isn't used, and all calls positioned to the leading web page are dealt with by using an attendant. there is a faraway site in Germany with the E.164 PSTN number +forty nine 404 13267. four-digit extensions are used at the German area, and DID is allowed as a result of digits can also be introduced to the PSTN quantity. When calling the German office attendant (now not knowing a specific extension), U.S. clients would dial 9-011-forty nine-404-13267. notice how the + is changed by the foreign prefix 011 and the access code 9. If the mobilephone with extension 1001 should be referred to as directly, 9-011-forty nine-404-13267-1001 needs to be dialed.
Variable-length numbering, E.164 addressing and DID
figure 1-5 illustrates an illustration wherein the leading web page with CUCM resides in the U.S. and a remote website without CUCM resides in Germany. The NANP PSTN number within the U.S. is 408-555-1234. word that DID isn't used, as a result of all calls placed to the leading site are handled via an attendant. A far flung web site in Germany has PSTN number +forty nine 404 13267. four-digit extensions are used at the German vicinity, and DID is allowed because digits will also be added to the PSTN quantity. When calling the German workplace attendant (now not realizing a specific extension), U.S. users would dial 9-011-49-404-13267. If the mobilephone with extension 1001 may still be referred to as directly, 9-011-49-404-13267-1001 has to be dialed.

The logic of routing calls by CUCM over the WAN or in the course of the PSTN is as it should be clear to the mobilephone consumer.
Optimized call routing and PSTN backup
There are two the right way to shop charges for PSTN calls in a multisite deployment:
within the instance proven in figure 1-6, a name from Chicago to San Jose would be routed as follows:

If the WAN were unavailable for any reason before the name, the Chicago Gateway would have to be thoroughly configured to route the name with the applicable digit manipulation throughout the PSTN at a doubtlessly larger toll cost to the San Jose PSTN cell.
NAT and safety concerns
In single-web page deployments, CUCM servers and IP phones always use inner most IP addresses as a result of there is not any need to communicate with the outside IP world. NAT isn't configured for the mobile subnets, and assaults from the outdoor are not possible. In multisite deployments, despite the fact, IP protection (IPsec) virtual deepest network (VPN) tunnels can also be used between websites. The VPN tunnels enable handiest intersite communication; entry to the protected internal networks isn't feasible from the backyard—handiest from the different web page through the tunnel. therefore, assaults from the outside are blocked at the gateway. To configure IPsec VPNs, the VPN tunnel ought to be configured to terminate on the two gateways within the distinct sites. on occasion this is now not feasible; for instance, both websites can be below distinct administration, or possibly security policies don't allow the configuration of IPsec VPNs.
In the sort of case, or when connecting to a public service akin to an ITSP, NAT has to be configured for CUCM servers and IP telephones. Cisco calls this Hosted NAT Traversal for Session Border Controllers.
In determine 1-7, business A and enterprise B both use IP community 10.0.0.0/eight internally. To communicate over the internet, the deepest addresses are translated into public IP addresses. business A uses public IP community A, and company B uses public IP network B. All CUCM servers and IP phones can also be reached from the internet and speak with each and every different.
As quickly as CUCM servers and IP phones can also be reached with public IP addresses, they're subject to assaults from the outside world, introducing skills security concerns.

Network SoftwarePress Release Summary:
Compatible with range of IP phone systems, EVOip v8.0 captures telephone calls from network and enables storage, playback, and archiving of entire interaction. It can record up to 280 channels simultaneously, including encrypted calls; offers keyword spotting (searching for spoken words); and provides adjustable modes for individual, bulk, or selective recording. Various functions may be accessed directly through IP phone, including start/stop, keep/delete, and search/replay.Original Press Release: ASC Introduces EVOip, Version 8.0, for Voice-over-IP Recording
Offers More Recording Channels and New Integrations
Hoesbach/Germany, January 17, 2008 - ASC (www.asctelecom.com), a leading global provider of innovative solutions to record, analyze and evaluate communications, today announced the introduction of EVOip 8.0, a new VoIP recording solution with additional channel capacity and compatibility with a wider range of IP phone systems.
EVOip Server Software now records up to 280 channels simultaneously, and, for the first time, integrates with PBXs from Avaya, Nortel, IP Trade and 3Com. In addition, IP phone applications and functionality with existing solutions for Alcatel, Cisco, Mitel and Siemens have been expanded. For example, EVOip+ for Cisco now works with the common SIP protocol, and record-on-demand may be easily initiated by a single button push on the phone itself. The active version, EVOip active for Cisco, is compatible with Cisco Unified Communications Manager 6.0 and higher.
Harald Zapp, Chief Operating Officer of ASC, said, "Our company has coordinated with leading telecommunications providers, often through rigorous partnership programs, to integrate and certify EVOip as a seamless extension of their proprietary IP phone systems. As a result, we can now offer our VoIP recording solution as a superior alternative to a broader range of customers, often in high-volume demanding environments."
Version 8.0 is more user-friendly because many functions may now be accessed directly through the IP phone. These include start/stop, keep/delete and search-and-replay for recorded calls. CTIntegration facilitates this search by tagging calls with more index data than ever before.
EVOip 8.0 now lets the user quantify the number of recordings on a daily, weekly, monthly or quarterly basis. It supports more languages including Chinese (Simple and Traditional), Dutch, English, French, German, Italian, Japanese, Korean and Spanish. The product also works with ASC's new Time & Alarm Manager (TAM) for synchronization and contact operation, and displays the current status of connected recorders. The TAM resides at its own IP address and distributes the time signal via network to ASC's communications recording system, MARATHON EVOLUTION.
EVOip captures telephone calls from the network and enables storage, playback and archiving of the entire interaction. It is entirely software-based and designed for maximum flexibility, scalability, and ease of integration and installation. It records encrypted calls, offers keyword spotting (searching for spoken words) and provides adjustable modes for individual, bulk or selective recording.
