Hello. I am sending outbound dtmf over g729 using rfc2833. Generally it works perfectly. The only issue is that, when 2 subsequent digits are the same, the receiver detects them as a single digit. For instance, if I send 1234, it is detected as expected as 1234. However, if I change that to 2234, it is detected as 234. I have played with rtp-digit-delay and dtmf-duration extensively to no avail. I've also tried both queue_dtmf and execute_on_answer=send_dtmf. Anyone have any ideas? Any help much appreciated. Here is the extension that I'm using in my dialplan: <extension name="test_conference"> <condition field="destination_number" expression="^test_conference$"> <action application="playback" data="wait.wav" /> <action application="set" data="effective_caller_id_number=5555555555"/> <action application="export" data="nolocal:absolute_codec_string=G729"/> <action application="flush_dtmf"/> <action application="queue_dtmf" data="2234"/> <!-- <action application="export" data="nolocal:execute_on_answer=send_dtmf 2234" />--> <action application="bridge" data="sofia/internal/${bridge_number}@${trunk_ip}" /> <action application="hangup" /> </condition> </extension> Thanks, Mark
