6.8.1 SIP Trunk for Inbound Verizon calls
This section describes the steps for administering the SIP trunk to Session Manager used for
Verizon IP Trunk service calls. Trunk 1 is defined. This trunk corresponds to the CM-TG2 SIP
Entity defined in Section 5.4.2.
6.8.1.1 Signaling Group 2
Step 1 - Enter the add signaling-group x command, where x is the number of an unused signaling
group (e.g., 2), and provision the following:
Group Type – Set to sip.
Transport Method – Set to tls.
Verify that IMS Enabled? is set to n.
Verify that Peer Detection Enabled? is set to y. The system will auto detect and set the
Peer Server to SM.
Near-end Node Name – Set to the node name of the procr noted in Section 6.4.
Far-end Node Name – Set to the node name of Session Manager as administered in
Section 6.4 (e.g., SM).
Near-end Listen Port and Far-end Listen Port – Set to 5071.
Far-end Network Region – Set the IP network region to 2, as set in Section 6.6.2.
Far-end Domain – Enter avayalab.com. This is the domain provisioned for Session
Manager in Section 5.1.
DTMF over IP – Set to rtp-payload to enable Communication Manager to use DTMF
according to RFC 2833.
Direct IP-IP Audio Connections – Set to y, indicating that the RTP paths should be
optimized directly to the associated stations, to reduce the use of media resources on the
Avaya Media Gateway when possible (known as shuffling).
Use the default parameters on page 2 of the form (not shown).
