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

[Robert Schuknecht]

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.
