That signaling stack is sangoma proprietary, they will need to provide the support for it.

Hi John,
Thanks for the reply, we have been following up with sangoma but we didn't get any solution or workaround from them. We hoped to find resolution from people who may have faced the same issue. Any insight much appreciated
Thanks Abhishek

I would imagine you would get better answers by speaking to Sangoma.

We are facing issues with sangoma card in the new hardware dell server
(Dell T30) with Xeon processor.
Also we have observed same issue in i7 based servers.
With same configuration, same pri and same sangoma card, it is working
fine in an old machine with intel core i3 and i5 processor.
We are using freeswitch v1.6.6 but on upgrading to freeswitch v1.6.19
issue still persists.
In this signalling layer does not come up on the new hardware Xeon, intel
core i7.
This is a new installation on a brand new dell server (Dell T30).

We had also upgraded the bios of the server but that had no effect
Also we were suggested to upgrade the bios to latest version. Which was

It seems we are receiving SABME but sending nothing in return. Their are
no RX and TX counter increment.
Do let me know if you need more information.
Any idea what could we do to mitigate this?
