Field descriptions for Group Member Assignments page
The total number of pages of the Trunk Group screen, and the page number of the first page of
Group Member Assignments, vary depending on whether the Administrable Timers and
ATMS Thresholds pages display. Note that the Group Member Assignments screen is
repeated, as needed, to allow assignment of all group members. This section does not cover
ISDN trunks. For descriptions of the screens and fields that are unique to ISDN trunks, see
ISDN Trunk Group
Note:
For SIP Enablement Services (SES) trunks, the group member-assignment
Note:
pages are not individually administrable. The system automatically populates and
displays these fields based on the number of members of SES trunk groups
specified on page 1. Note that these display-only group member-assignment
pages of the Trunk Group screen are repeated, as needed, to support all the
trunk group's members.
Usage
When the field is set to y, URIs in call control signaling messages
originated at the gateway are encoded with the "user=phone" parameter.
No subscription messages are encoded with the "user=phone" parameter
even when the field is set to y. Default is n.
Note: Do not change the default of 'no' (n) for this field unless you are sure
that every recipient of SIP Enablement Services (SES) calls via this trunk
can accept and properly interpret the optional "user=phone" parameter.
Enterprise users without support for "user=phone" in their SIP Enablement
Services (SES) endpoints will experience adverse effects, including
rejected calls.
