Instant Defines whether the SIP 'tgrp' parameter is
used, which specifies the Trunk Group to
which the call belongs, according to RFC
4904.
For example:
INVITE sip:+16305550100
; tgrp=1;
trunkcontext=example.com@10.1.0.3;
user=phone SIP/2.0
Disable – ‘tgrp’ parameter is not used.
Send Only – the trunk group number is
added as the 'tgrp' parameter to the
Contact header of outgoing SIP
messages. If a trunk group number is not
associated with the call, the 'tgrp'
parameter isn't included. If a 'tgrp' value
is specified in incoming messages, it is
ignored.
Send And Receive – The functionality of
outgoing SIP messages is identical to the
functionality described in Send Only
option. In addition, for incoming SIP
messages, if the Request-URI includes a
'tgrp' parameter, the gateway routes the
call according to that value (if possible). If
the Contact header includes a 'tgrp'
parameter, it is copied to the
corresponding outgoing messages in that
dialog.
UCR 2008 = Interworks the hotline "Off
Hook Indicator" parameter between SIP
and ISDN.
Hotline Extended = Interworks the ISDN
Setup messages hotline "OffHook
Indicator" Information Element (IE) to SIP
INVITEs Request-URI and Contact
headers.
