[Freeswitch-users] ptime transcoding does not pass rfc2833

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
