ADTRAN 644 NetVanta Configuration for MaxCS 7.5

This article describes how to configure an ADTRAN 644 gateway as a T1 PRI trunk to MaxCS Release 7.5. During these instructions, you will edit a default configuration file that has been provided by AltiGen. This configuration file, adtranpri2.cfg, is attached to this article in the AltiGen Knowledgebase.


  • The server must be running MaxCS Release 7.5
  • Your device must be an ADTRAN NetVanta model 644

Configuration Steps - MaxAdministrator

The MaxCS SIP Trunks should match the number of PRI trunks on your ADTRAN device. For example, 46 PRI channels should be configured as 46 SIP Trunk channels in MaxCS.

These steps assume that you are familiar with MaxAdministrator.
  1. Open MaxCS Administrator and choose PBX > Trunk Configuration.
  2. Add a new SIP trunk, naming it ADTRAN. Set the trunk's SIP Protocol field to From Header.
  3. Configure the SIP Trunk's parameters as follows:
