How to setup ISDN UD-64 Data connection over VOIP
Posted by Markus Zeier, Last modified by Daniel Lizaola on 14 December 2017 05:26 PM

ENFORCE THE TRANSPARENT CODEC FOR ISDN UD-64 CALLS:

Incoming ISDN calls will be split into two call-router paths to enforce transparent codec for ISDN unrestricted digital calls.
Note that the VOIP-DATA interface has no route into the call-router, it operates as a one-way interface. However it has a special Voip-Profile linked, which only contains the transparent codec.
The VOIP-DEFAULT interface will be used for incoming voip calls. It uses the default voip profile, which is linked in the voip gateway.
The default profile contains the transparent codec with the lowest priority to ensure that voice calls never uses the transparent codec.
