For my gateway, I had to set ignore_early_media=true.

Mathieu Rene Avant-Garde Solutions Inc Office: + 1 (514) 664-1044 x100 Cell: +1 (514) 664-1044 x200 mrene@avgs.ca On 20-Aug-09, at 3:29 AM, Matthew Fong wrote: I'm trying to get FreeSWITCH to bridge two channels together through the same external gateway, but I'm having issues hearing audio. Both legs if setup independently and forwarded to 5000 (test ivr) work fine for both inbound and outbound media, but when I try to bridge them together, everything seems fine in FreeSWITCH, but neither party can hear the other speak. I'm thinking the external gateway might be having some issues because I've been able to bridge 2 channels together through the same gateway on different providers, but thought I'd also try to seek some help here. FreeSWITCH should be handling the media for both channels, so I can't figure out why if Leg A and Leg B work independently, but not if they are bridged together. Is there a setting somewhere in FS that I'm missing? Below is a ngrep of the SIP interactions if it's useful.
