Hi buddies,<br>I encountered DTMF issue when I tried to place call from x-lite to a<br>sip conference serice,here is the diagram.<br>X-lite---->Asterisk--->Cisco SIP proxy---->SIP Conference service<br><br>The Call can be established,and I can hear from x-lite the prompt of
<br>the conference,but when I input any digits,nothing happened,the<br>conference service did not recognize my input.At the same time,in the<br>log of asterisk,I can find that asterisk recognized all the<br>digits....I tried "rfc2833","inband","info" in the "dtmfmode"
<br>parameter,but did not work ,I'm not sure whether asterisk send the<br>right dtmf to cisco proxy,how can I track that?<br><br>I made another test,dialing from x-lite registered with Cisco proxy to<br>voicemail service of Asterisk.
<br>x-lite---->Cisco SIP proxy---->Asterisk--->Voicemail service<br><br>Both the call and dtmf worked fine,I can input my mailbox number and<br>password and listen my voicemail.both "rfc2933" and "inband" worked
<br>in this situation,but not "info".<br><br>My Asterisk is 1.4.4 with asterisk now,I did not configure dtmfmode in<br>the section of xlite and the trunk to cisco proxy,just configure the<br>dtmfmode in sip.conf
.<br><br>When I used "rfc2833",I can see the log in asterisk as :<br><br>[2007-06-19 16:01:40] DTMF[8925] channel.c: DTMF begin '2' received on<br>SIP/9999-08269470<br>[2007-06-19 16:01:41] DTMF[8925] channel.c
: DTMF end '2' received on<br>SIP/9999-08269470, duration 160 ms<br>[2007-06-19 16:01:42] DTMF[8925] channel.c: DTMF begin '1' received on<br>SIP/9999-08269470<br>[2007-06-19 16:01:42] DTMF[8925] channel.c
: DTMF end '1' received on<br>SIP/9999-08269470, duration 140 ms<br><br>and when I used "inband",I can see :<br><br>[2007-06-19 15:55:21] DTMF[8852] channel.c: DTMF end '2' received on<br>SIP/9999-09d916c0, duration 0 ms
<br>[2007-06-19 15:55:22] DTMF[8852] channel.c: DTMF end '1' received on<br>SIP/9999-09d916c0, duration 0 ms<br><br>Is that right?Can I check what digits that asterisk sent out ?<br><br>How can I track where is wrong with the dtmf?Did asterisk send dtmf to
<br>Cisco proxy correctly?<br>I really have no idea about that.Please advise.Thank you very much!!!!<br><br>_______________________________________________<br>--Bandwidth and Colocation provided by <a href="http://Easynews.com">
