server and Communication Manager must be configured with the appropriate H.323
parameters. To convert an individual telephone from H.323 to SIP, both the SIP
Enablement Services (SES) server and Avaya Communication Manager (CM) must be
configured with the appropriate SIP parameters. Any telephone in use prior to conversion
must run Release 2.0 or greater software with a SIG parameter value of “default” (H.323).
See Table 1
, the H.323 to SIP and SIP to H.323 Conversion Chart for conversion
instructions.
● SIP-Centric - an environment where the majority of IP telephones are or will become SIP
telephones running SIP software. In a SIP-centric environment, the 46xxSIP... software
bundle must reside on the HTTP server and both SES and CM must be configured with the
appropriate SIP parameters. To convert an individual telephone from SIP to H.323, Avaya
Communication Manager (CM) must be configured with the appropriate H.323
parameters. Any telephone in use prior to conversion must run Release 2.0 or greater
software with a SIG parameter value of “default” (SIP). See Table 1
, the H.323 to SIP and
SIP to H.323 Conversion Chart for conversion instructions.
What makes an environment H.323 or SIP depends on the type of upgrade script files the
environment is running (H.323 or SIP) and the Signaling Protocol Identifier (SIG) parameter
setting. The SIG parameter has three possible values:
● Default - either H.323 or SIP, set automatically for all telephones depending on the nature
of files downloaded to the SES server or Communication Manager.
● H.323 - manually set to H.323 for a specific telephone by an installer or administrator
according to the procedures in this section.
● SIP - manually set to SIP for a specific telephone by an installer or administrator according
to the procedures in this section.
Converting 4610SW/4620SW/4621SW IP Telephones
An H.323 IP telephone can be either in use with possible customized settings or out of the box
with factory default settings. An out of the box telephone requires accessing the manual
programming mode early in the process and setting the Signaling Protocol Identifier (SIG)
parameter to “SIP.” Converting to SIP early avoids having to first load H.323 software, log in,
and then invoke the “in use” process to load the SIP software.
Note:
Note: For information about the SIG parameter, see “Choosing the Right Application
File and Upgrade Script File” in the 4600 Series IP Telephone LAN Administrator
Guide (Document Number 555-233-507). For information on setting or changing
the SIG parameter, see Signaling Protocol Identifier
on page 64.
