IP Office Release 7.0

Page 259

Issue 22.a.- (21 March 2011)

From IP Office Release 2.1(35) and higher, Multi-Site Networking 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 Multi-Site network 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, Multi-Site Networking (SCN) requires one or more additional licenses.

QSIG, H.323 and Multi-Site (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.

Internetworking with Other Avaya Products

IP Office will support the most appropriate way for communication with any other existing PBX's in a customer

network, whether TDM or IP-based. With Avaya DEFINITY, MultiVantage, Avaya Integral Enterprise or Avaya

AURA® Communication Manager (ACM), the protocols used will be QSIG or H.323 over T1, E1 or IP links

VoIP networking using H.323

IP Office (since release 1.1 in US and release 1.2 in EMEA) has been successfully tested to be interoperable

over IP trunks with Avaya Communication Manager (ACM). The protocol supported is H.323 using

industry-standard compression codecs (types G.711A, G.711MU, G.729A and G.723.1-6K3). The features

currently supported are:

· Desk to desk dialing (basic voice call)

· Calling/Connected Party ID number

· Calling/Connected Name Presentation

· Call Hold

· Call Transfer

These features allow for simple networking needs between IP Office remote branches to a DEFINITY/ACM at the

main site.

QSIG networking using T1/E1 links (TDM)

Alternatively QSIG may be favored as the chosen signaling standard within multiple vendor environments and

provides the following supplementary services which are also available between IP Office and DEFINITY /

MultiVantage/ I55 /ACM (equipped with the relevant RFA licenses):
