Alcatel OmniPCX Enterprise SIP Trunk
Integration
This chapter describes how to integrate Alcatel OmniPCX Enterprise telephony
system version 8.0 with the EasyCall Gateway through a SIP trunk.
The integration described in this chapter can be done in tandem with EasyCall
Gateway installation and configuration, which includes defining the properties of the
telephony system trunk and defining any changes the EasyCall Gateway makes to
telephone numbers before sending them to the telephony system for dialing. For SIP
trunks, the EasyCall Gateway always listens on port 5060. By default, the EasyCall
Gateway communicates with the SIP trunk over port 5060; that port is configurable.
For information about EasyCall Gateway configuration, refer to the
EasyCall Gateway
Administrator’s Guide
.
Those responsible for configuring the telephone system must have the specific
characteristics for the site available before attempting to integrate the EasyCall
Gateway. Integrating the telephone system with the EasyCall Gateway is similar to
integrating the telephone system with a voicemail system.
