<p>Hello,</p>
<p>I think there is an issue when DTMF are handled with SIP INFO and
direct media is enabled.</p>
<p>When I receive a SIP INFO, the logs tell me that a "DTMF begin"
is generated, but no related "DTMF end" is generated, unless the
call is ended. Here is an excerpt of the logs :</p>
<p><b><tt>--- SIP INFO received </tt></b><b><tt>on</tt> </b><b><tt>SIP/xxx-00000004:</tt></b></p>
<p><tt>[Dec 13 11:56:16] DTMF[18193][C-00000005] channel.c: DTMF end
'#' received on SIP/xxx-00000004, duration 257 ms</tt><tt><br>
</tt><tt>[Dec 13 11:56:16] DTMF[18193][C-00000005] channel.c: DTMF
begin emulation of '#' with duration 257 queued on
SIP/xxx-00000004</tt></p>
<p><b><tt>--- </tt></b><tt><tt><b>SIP/xxx-00000004 </b><b>is
hanged up:</b><br>
</tt></tt></p>
<p><tt></tt><tt>[Dec 13 11:56:19] VERBOSE[18193][C-00000005]
bridge_channel.c: Channel SIP/xxx-00000004 left 'native_rtp'
basic-bridge <4a5905ac-29f8-41c5-9981-<wbr>e9d0f4966c56></tt><tt><br>
</tt><tt>[Dec 13 11:56:19] DTMF[18193][C-00000005]
bridge_channel.c: DTMF end '#' simulated to bridge
4a5905ac-29f8-41c5-9981-<wbr>e9d0f4966c56 because SIP/xxx-00000004
left. Duration 3012 ms.</tt></p>
<p>Do you think it is a bug ? I would tend to say yes, but I'm not
so sure.</p>
<p>Regards</p><span class="HOEnZb"><font color="#888888">
