User's Manual
Assigns an IP Group to where the device sends INVITE messages
for calls received from the Trunk Group. The actual destination to
where the INVITE messages are sent is according to the Proxy Set
associated with the IP Group. The Request-URI host name in the
INVITE and REGISTER messages (except for 'Per Account'
registration modes) is set to the value of the 'SIP Group Name'
parameter configured in the IP Groups table (see ''Configuring IP
Groups'' on page 333).
Note:

If the parameter is not configured, the INVITE messages are
sent to the default Proxy or according to the Tel-to-IP Routing
table (see ''Configuring Tel-to-IP Routing Rules'' on page 475).

If the PreferRouteTable parameter is set to 1 (see ''Configuring
Proxy and Registration Parameters'' on page 365), the routing
rules in the Tel-to-IP Routing table take precedence over the
selected Serving IP Group ID.

[1] Use Activate Only = MWI Interrogation messages are not
sent and only "passively" responds to MWI Activate requests
from the PBX.

[2] Result Not Used = MWI Interrogation messages are sent, but
the result is not used. Instead, the device waits for MWI Activate
requests from the PBX.

[3] Use Result = MWI Interrogation messages are sent, its
results are used, and the MWI Activate requests are used. MWI
Activate requests are interworked to SIP NOTIFY MWI
messages. The SIP NOTIFY messages are sent to the IP Group
defined by the NotificationIPGroupID parameter.
Note: The parameter appears in the table only if the
VoiceMailInterface parameter is set to 3 (QSIG) (see Configuring
Voice Mail on page 572).
