[Freeswitch-users] Inband DTMF Problem

[Klaus Teller]

HI,

I'm attaching the console log and event-socket traffic. In the latter case, i gathered only the last few Digits (including the spurious one).

I also have the wireshark trace that i can send you off the list if you wish. 

We ran the same IVR (VoiceXML App) with a platform that supports RFC2833 i didn't have this problem. With this platform we unfortunately don't have this feature available.


Klaus.
