Hi,


What is the other end-point ? X-lite is know to work with cisco.

If need something changed in X-lite you have to check with counterpath

The SDP & Attributes for Media is coming from Cisco Router, so no changes are required from X-lite

Hi,


I guess you are referring to the SDP part present in calls from "cisco voice gateway router" to x-lite.


In fact it is correct that the router is presenting these and in my expereince X-lite has no problem in answering the call as long PCM codec is configured in there.


Hope this helps, please rate post if it does!
