• Entity Link 2: SM1 port 5061 to CM1TRNK
port 5061
For TCP, use port 5060 instead of 5061.
Note:
With the sample configuration, signaling-group 1 and entity link 1 are logically paired-
up to handle SIP OPS station signaling, and signaling-group 2 and entity link 2 are
logically paired-up to handle inbound call signaling. However, you must administer
appropriate routing in Session Manager, as well as in Communication Manager, to
ensure that the appropriate traffic is routed over the appropriate signaling facilities. You
can add additional signaling groups on Communication Manager by using the same
entity links defined in Session Manager, as indicated in the table, as more OPS
signaling trunks and more inbound signaling trunks might be required in
Communication Manager to handle the required call traffic load and the required
number of SIP agent deskphones.
5. In the
DTMF over IP
field, select
rtp-payload
.
6. In the
Session Establishment Timer
field, enter
3
, which is the recommended time period
for call center use.
7. In the
Far-end Network Region
field, assign a number from
1
to
250
that represents the
region of Session Manager.
8. In the
Far-end Domain
field, assign the IP address of the SIP domain.
9. In the
Initial IP-IP Direct Media
field, select
n
. This field option is necessary to prevent
unexpected interactions with the Call Center Elite features as some features depend on
the media that Communication Manager handles during the first few seconds.
10. In the
Direct IP-IP Audio Connections
field, select

Administering the Trunk Group screen
The following procedure and settings refer to the trunk groups that are used only for SIP signaling
to the SIP agent deskphones. For more information, see
