Are you running the latest version? It appears the dtmf is failing a sanity check and getting ignored as a result, possibly as a result of the device sending the wrong rtp timestamps. Can you get a tcpdump of the rtp stream? Steve on iPhone On 3 Mar 2011, at 22:50, Johannes Jakob <jjj@3js.de> wrote:
Hi,
what do I have to do to get RFC2833 DTMF passed to the client in an inbound scenario like this:
Upstream >rfc2833> FreeSWITCH >rfc2833> Asterisk
?
The Upstream is sending the DTMF tones correctly:
--- 329 2.114845 UPSTREAMIP FS_IP RTP EVENT 62 Payload type=RTP Event, DTMF Eight 8 ---
FreeSWITCH isn't logging much of the dtmf stuff, even with loglevel debug:
http://pastebin.freeswitch.org/15541
... Set 2833 dtmf receive payload to 101 ... 2011-03-03 23:29:59.498466 [ERR] switch_rtp.c:282 Failed DTMF sanity check. ...
User's directory entry includes:
<param name="dtmf-type" value="rfc2833"/> <param name="pass-rfc2833" value="true"/>
I tried adding those in the gateway profile as well, no change.
On the asterisk box I don't see those rtpevents in the pcap trace anymore, they just vanish on the FS box.
Can somebody help me out here? Or point me to the right wiki page? http://wiki.freeswitch.org/wiki/Sofia_Configuration_Files#DTMF doesn't really tell me, what the options do and http://wiki.freeswitch.org/wiki/DTMF is something different.
Thanks and bye,
