Converting 9600 Series Ip Telephones - Avaya one-X 9600 Series Installation And Maintenance Manual

There are several H.323 to SIP or SIP to H.323 conversion scenarios, and each scenario
depends on whether the majority of your telephones are H.323 or SIP:
H.323-Centric - an environment where the majority of IP telephones are and will remain
running H.323 software, but some telephones will become SIP IP telephones. In an
H.323-centric environment, the appropriate H.323 telephone binary files must reside on
the HTTP 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 S1.2 or greater software with a SIG parameter value of "default"
(H.323). See
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 96xxSIP... 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 SIP telephone in use prior to conversion must run Release SIP 1.0 or
greater software with a SIG parameter value of "default" (SIP). See
SIP and SIP to H.323 Conversion Chart
What makes an environment H.323- or SIP-centric depends on the type of upgrade script files
the environment is running (H.323 or SIP, see
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 whether
your environment is H.323-centric or SIP-centric as determined by the software bundle
downloaded and the changes you make to the alternate_96xxupgrade.txt file.
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 9600 Series 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 you want to convert to SIP requires
accessing the SIG Craft procedures early in the power up and initialization process and setting
the Signaling Protocol Identifier (SIG) parameter for that telephone 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.
