Integration Overview
The EasyCall Gateway has been certified for interoperability with Nortel
Communication Server 1000 version 5.0. The EasyCall Gateway supports SIP and
QSIG trunks.
To enable the EasyCall Gateway to work with the Nortel system, you must configure
the telephony system trunk between the EasyCall Gateway and the Nortel system.
EasyCall Gateway integrated with Nortel Communication Server
The integration described in this guide 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 information
about EasyCall Gateway configuration, refer to the
EasyCall Gateway Administrator’s
Guide
.
Those responsible for configuring the telephone system must take the specific
characteristics of a site into consideration to determine the appropriate settings.
Configuration of the Nortel telephone system for integration with the EasyCall Gateway
is similar to integration with a voicemail system.
The following topics describe how to configure trunks for the supported Nortel
systems.
