This guide describes how to configure T1 Centrex support for MAXCS 8.0 deployments using an AudioCodes Mediant series gateway.

For instructions on setting up the gateway device's firewall, refer to Article 1242. 

Please note the following considerations before you begin the procedures in this guide:

• The examples in this guide illustrate the configuration for a Mediant 1000B gateway.  For other models, adjust the port settings as needed. This document should also apply to Mediant 800B with a voice T1 interface.

• AltiGen does not provide general configuration support for AudioCodes devices. Contact AudioCodes support for assistance with general setup.

• T1 CAS Centrex transfer support is a special configuration for the Mediant 1000 gateway. You must dedicate the Mediant 1000 gateway to this purpose only. AltiGen will not support additional non-T1 CAS Centrex configuration to the same gateway. In other words, no additional PRI, non-Centrex T1 CAS and FXO, FXS ports should be used on this gateway. For additional FXS and FXO support, we recommend that you use an AudioCodes MP-1xx gateway.
