Nortel SIP Trunk Integration
This chapter describes a sample configuration of Nortel telephony system for
integration with the EasyCall Gateway through a SIP trunk. The example
configurations are performed through the Nortel CS 1000 Element Manager and Nortel
overlays.
Please note the following regarding Nortel SIP trunk integration:
•
When a call is made, there are two SIP virtual channels used on the CS 1000.
These are local loopback virtual channels.
•
The EasyCall Gateway supports only the URI format number@IpAddress
([email protected]) and not the URI format [email protected]
([email protected]). This prevents the EasyCall Gateway from working
with a Nortel CS1000 SIP Gateway via Nortel SPS/NRS. Therefore, a direct SIP
connection should be set up between the CS1000 SIP GW and the EasyCall
Gateway without SPS involvement.
The following topics describe a sample configuration of Nortel SIP trunks:
“Configuring the IP Peer Network in Communication Server 1000” on page 3
“Configuring the SIP Route and Trunks on the Call Server” on page 11
“Verifying the Integration” on page 14
Configuring the IP Peer Network in Communication
Server 1000
The SIP Trunk Gateway runs only on the Signaling Server. You must configure both
the Signaling Server, using the CS 1000 Element Manager as described in this
section, and the Call Server, as described in “Configuring the SIP Route and Trunks on
the Call Server” on page 11.
The following topics describe how to use the Element Manager to configure the SIP
Trunk Gateway on the Signaling Server:
“Enabling the SIP Trunk Gateway (SIP Virtual Trunk Application)” on page 4
“Configuring the SIP Trunk Gateway” on page 8
“Configuring Voice Codec for Nortel IP Phones” on page 9
“Restarting the Signaling Server” on page 11
