Hello,

I have a problem with sending dtmf events (rfc2833) with uuid_send_dtmf api command.

FreeSWITCH Version 1.5.15b+git~20141118T231404Z~df423b88d6~64bit (git df423b8 2014-11-18 23:14:04Z 64bit)

First i originate the call and park it with the command:

originate {origination_caller_id_name=test}sofia/gateway/test/xxxxxxxx@yyy.zzz.com &park()

The other side answers the call. I can see that rfc 2833 is negotiated in SDPs.

   SIP/2.0 200 Ok

   Via: SIP/2.0/UDP 46.174.232.238:5070;rport;branch=z9hG4bKFmQvapcNNp44m

   From: "..." <sip:...@...>;tag=35FN6HXZ3ry2F

   To: <sip:12122777254@sip.12voip.com>;tag=f0313ac544a16a82aee0b

   Contact: sip:...@...:5060

   Call-ID: f7b0d42d-ed32-1232-06a5-c03fd5651f3e

   CSeq: 68010140 INVITE

   Server: (Very nice Sip Registrar/Proxy Server)

   Allow: ACK,BYE,CANCEL,INVITE,REGISTER,OPTIONS,INFO,MESSAGE

   Content-Type: application/sdp

   Content-Length: 211

   v=0

   o=xxx 1416695524 1416695524 IN IP4 yyyy

   s=SIP Call

   c=IN IP4 yyyy

   t=0 0

   m=audio 27792 RTP/AVP 8 101

   a=rtpmap:8 PCMA/8000

   a=rtpmap:101 telephone-event/8000

   a=ptime:20

Then I try to send DTMF

freeswitch@internal> uuid_send_dtmf 6022b884-7297-11e4-8682-fd8246740d0e 12345

digit=5 ms=250 samples=2000

Unfortunatelly it doesn't work and I can't see any rtpevents in wireshark.

If I change dtmf-type in profile to info, i can see  sip info packets.

Please help
