Changing the signaling protocol
About this task
For enterprises requiring both H.323 and SIP-based protocols, you can specify the protocol for all
or specific deskphones in the following two ways:
Procedure
1. As of Release 6.0, you can set the SIG parameter in DHCP Option 242 (Site-Specific
Option Number) or in the 46xxsettings.txt file.
This setting will apply to all telephones except those for which SIG has been manually
configured to a value of H.323 or SIP using the SIG Craft procedure.
2. You can set the SIG parameter on a per-phone basis using the SIG Craft procedure.
Applying settings to logical groups
You might have different communities of end users with the same phone model but requiring
different administered settings. For example, you might want to restrict Call Center agents from
logging out, an essential capability for
hot-desking
associates. This section provides examples of
the group settings for each of these situations.
You can separate groups of users is to associate each of them with a number. Use the GROUP
parameter for this purpose. You cannot set GROUP system value in the 46xxsettings file. The
GROUP parameter can only be set on a phone-by-phone basis. To set the GROUP parameter,
first identify which phones 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. The largest group is
assigned as Group 0.
Then, at each phone that does not have default parameters, instruct the installer or end-user to
invoke the GROUP Local Administrative Craft procedure. After the GROUP assignments are in
place, edit the configuration file to allow each phone 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 CALLCENTER IF $GROUP SEQ 2 goto HOTDESK
{specify
settings unique to Group 0}
goto END
# CALLCENTER
{specify settings unique to Group 1}
goto END
# HOTDESK
{specify settings unique to Group 2}
# END
{specify settings common to all Groups}
