Small Community Networking

When connecting IP Offices together over IP or Packet based networks, Small Community Networking enhances feature transparency. These networks can support up to a maximum of 1000 users across 32 sites. The following additional features are available.

Busy Lamp Field
Camp-on
Call Back When Free
Paging
Call Pick-up
Centralized Personal Directory for 1400, 1600, 9600 and T3 Telephones as well as one-X Portal for IP Office
Centralized System Directory for 1400, 1600, 9600 and T3 Telephones as well as one-X Portal for IP Office
Centralized Call Log for 1400, 1600, 9600 and T3 Telephones as well as one-X Portal for IP Office
Centralized Voice Mail (Preferred Edition)
Support for mailboxes, call recording, dial by name and auto attendants. Remote queuing on remote systems is also supported.
Internal Directory
Absence Text Message
Anti-Tromboning.
Distributed Hunt Groups
Hunt groups can include users located on other IP Office systems within the network. Note that Distributed Hunt Groups are not supported for use with CCC and CCR
Remote Hot Desking
Users can hot desk between IP Office systems within the network. The system on which the user configured is termed their 'home' IP Office; all other systems are 'remote' IP Offices. Note that Remote Hot Desking is not supported for use with CCC and CCR
Breakout Dialing
This feature allows the user to select an IP Office system in the network from a displayed list and then dial a subsequent number as if dialing locally on the chosen system. This feature is triggered either by a programmable button or short code.

Resilient SCN (see the diagram below)
In an SCN configuration of System "A" and System "B" where the centralized voicemail is connected to System B, and a number of IP phones are connected to either System A or System B.  If System "B" fails then:
System A will automatically take over from System B and support Avaya IP phones, hunt groups, and DHCP if required
VoiceMail Pro will reregister to System A
All System B users will have the use of their UMS and Mobility licenses on System A (no other licenses will be available)
All System B users’ Personal contacts/Call Logs will continue to be available (1600 Telephones)

For Small Community Networks VCM modules are required in all systems being connected. The IP lines may be configured in a start or a meshed configuration. One of the advantages of a meshed configuration is that it removes the risk of a single point of failure within the network. Also the names and numbers (groups, line, services, etc) on the separate IP Office systems should be unique to reduce potential maintenance confusion.

Each IP Office system broadcasts UDP messages on Port 50795. These broadcasts typically recur every 30 seconds but BLF updates are potentially more frequent. There are no updates if there is no activity and the overall level of traffic is very low – typically less than 1 kbps per system.

From IP Office Release 2.1(35) and higher, SCN is supported between IP Office systems with differing software levels but network features will be based on the lowest level of software within the network. This option is intended to allow the phased upgrading of sites within a SCN and it is still recommended that all systems within a network are upgraded to the same level where possible.

If larger networks are required QSIG can be used to link multiple Small Community Networks together. Functionality between the communities is governed by the QSIG feature set.

IP500 Voice Networking License
On IP500 and IP500 V2 systems, Small Community Networking requires one or more additional licenses.

QSIG, H.323 and SCN capabilities are not enabled by default in the IP500 and IP500 V2. An additional license is required to enable this functionality with 4 simultaneous networking channels (no channel limit for QSIG). Additional channels can then be licensed in increments of 4. A Voice Networking license is still required to enable TDM QSIG, even though there is no limit to the number of TDM QSIG calls that can be made or received once licensed.
