ISDN PRI with Trunkgroup Configurations

 

 

Introduction

This document explains "How to Add/Modify the User-Agent SIP header in the SIP Profiles ?" . Sometimes SIP header Modification is required in a Service provider network where the Device rejects an unknown header and expects optional header value or parameter.

 

Problem description

 

 

I have a Voice Gateway with E1 ISDN PRI connection terminated to the Service Provider. I want to assign only 15 channels to this specific operator and rest to some other Service Provider. Is this Possible ?
