[cisco-voip] Antw: RE: Clear Channel Codec between Cisco GW andPattonSmartnode - Solution -

[Brian Turnbow]

Thanks for the update
We use Patton 4634 4638 models and T.38 gives us trouble sending from patton to cisco.
T.38 gets negotiated, we see the bidirectional t38 packets and everything looks ok (we see spedd negotiation ced tones ecc.)
but the fax fails with a transmission error.
Faxes from cisco to patton work without problems. 
 
The analog model Pattons give us no troubles.
Maybe we need to give the 1200 a try  

Brian

I got it working now. The problem with the clear-channel codec was, that the RTP Payload-Type was different
on the Cisco-Side than on the SmartNode Side. The default RTP Payload-Type is 125 on the Cisco-GW, but the 
SmartNode needed 116. So i changed it on the Dial-Peers with the command "rtp payload-type cisco-clear-channel 116", also
you need the actual Firmware on the Smartnode.

Regarding T.38 and FAX Passthrough, i had no problems at all. It worked from the beginning.
