Changing the signaling protocol
About this task
For enterprises requiring both H.323-based and SIP-based protocols, there are two ways to
specify the protocol to be used by all or specific phones:
Procedure
1. The SIG parameter can be set in DHCP Option 242 (Site-Specific Option Number) or in the
46xxsettings.txt file. This setting will apply to all phones except those for which SIG
has been manually configured to a value of H.323 or SIP using the SIG Craft procedure.
2. The SIG parameter can be set on each phone.
The GROUP parameter
You might have different communities of end users, all of which have the same model deskphone,
but which require different administered settings. For example, you might want to restrict Call
Center agents from being able to log off, which might be an essential capability for "hot-desking"
associates. We provide examples of the group settings for each of these situations later in this
section.
The simplest way to separate groups of users is to associate each of them with a number. Use the
GROUP system value for this purpose. The GROUP system value cannot be set in the
46xxsettings.txt file. The GROUP system value can only be set on each deskphone using a
Craft procedure. To set up groups, first identify which deskphones are associated with which group
and designate a number for each group. The number can be any integer from 0 to 999, with 0 as
the default, meaning your largest group would be assigned as Group 0.
Then, at each non-default deskphone, invoke the GROUP Local (Craft) Administrative procedure
and specify which GROUP number to use. Once the GROUP assignments are in place, edit the
configuration file to allow each deskphone of the appropriate group to download its proper
settings.
Here is an illustration of a possible settings file for the example of a Call Center with hot-desking
associates at the same location:
IF $GROUP SEQ 1 goto GROUP1 IF $GROUP SEQ 2 goto GROUP2 {specify settings unique to
Group 0} goto END # GROUP1 {specify settings unique to Group 1} goto END # GROUP2
{specify settings unique to Group 2} # END {specify settings common to all Groups
