Hello,<br>
<br>
I'm not sure which one is it. But I think I send the digits in RFC 2833. All devicves are supporting RFC 2833.<br>
</blockquote><div><br>Actually, that's very interesting. The start_dtmf app looks for in-band DTMFs, so if you have to have that in order to hear digits from the other end then the other end most definitely isn't doing RFC2833. <br>
<br>For the sake of testing, try sending in-band and see how the other end reacts. Might want to check this out:<br><a href="http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_start_dtmf_generate">http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_start_dtmf_generate</a><br>
<br>My guess is that the equipment along the way is futzing with things. FreeSWITCH does break easily but it does find bugs in other VoIP systems that it talks to... :)<br><br>-MC<br> <br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

Hello,<br>
<br>
I have problems with sending DTMF. The freeswitch server recieves the digits from my telefon (SIP account) if I activate DTMF with:<br>
<action application="start_dtmf"/><br>
in my dialplan.<br>
<br>
The line<br>
<--param name="dtmf-type" value="rfc2833"/--><br>
in sofia.conf.xml is active, too.<br>
<br>
But than I have the problem that the other phone doesn't work. It is a VoATM device. The curious thing is that I see the digits in the logfile whiche were sent from the phone. In the first example I saw nothing.<br>
<br>
Does anybody have an idea???<br>
<br>
<br>
Are you trying to send digits inband or RFC2833? Unless there's a compelling reason not to, we recommend 2833. What is the equipment on the far end looking for?<br>
<br>
