did you verify if the calls work fine from the ISDN to a phone connected to the PBX too?

This is to verify that you dont have a clocking issue on the 2Mbps ISDN trunk..

 

I believe that the issue is only encountered at the remote site – i.e. through a call place over the SIP trunk, but I will need to check on this. This means that normal calls to the main office all work correctly. It is only when the call is transferred to a remote location that the issue arises. I also believe that the issue can be reproduced simple by making a call to a remote extension from the main office which would just use obviously the SIP trunk (no ISDN/PSTN involved).
