Hi,

Does anyone know if this is a bug or a setting?

If I use an incoming call ptime of say 40 on gsm to save client bandwidth and output to a carrier at 20 the rtp is transcoded to the smaller ptime fine but any rfc2833 dtmf signalling is not passed through.

I have tried the pass_rfc2833 setting both on and off but it has no effect.

I have done some web searches but can find nothing refering to this issue.

Any help you could offer would be greatly appreciated.

FreeSWITCH version: 1.0.head (git-58c3c3a 2011-11-22 18-22-57 -0600)

Regards

Chris
