Is there anything obvious I can check in the rtpevent packets to suggest why FreeSWITCH would: - For UAC A - report receiving DTMF and successfully forward it to the bridged UAC - For UAC B - report receiving DTMF and *not* forward it. Both UAC's A and B show freeswitch reporting it has received the DTMF but only DTMF from UAC A gets forwarded to the bridge. Same dialplan/sip_profile/dialled extension. I feel sure it must be something within the DTMF packet itself that FreeSWITCH is not liking and therefore not forwarding On 4 June 2015 at 17:12, Pete Kelly <pkelly@gmail.com> wrote:
Hi
I am trying to send rfc2833 DTMF with SIPP into FreeSWITCH and have the DTMF be passed along to the bridged leg.
If I set up the following scenario:
Bria > FreeSWITCH > SIPP
and press a DTMF tone on Bria, I see the DTMF received in FS and then it being sent out to the bridged leg.
However if I replace Bria with SIPP and play one of the SIPP supplied rfc_2833 pcaps, I only see the DTMF being received by FreeSWITCH but it is not sent to the bridged leg.
Does anyone have any suggestions?
