On the very latest GIT and previous , Freeswitch doesn't seem to set the first Marker Bit to true on an rfc2833 event on the bleg of a call out to a gateway<br><br>on the A-leg the first event from my UA to Freeswitch is correct with duration as 0 and Marker bit set to True. Then the second event increments the duration and Market bit is set to false.<br>
but on the B-leg from freeswitch to the cisco gateway the first event has duration 80 (may or may not be a problem) but the Marker bit is set to False which must be wrong ? Duration then increments and Marker bit remains false.<br>
<br>I also tried <param name="manual-rtp-bugs" value="START_SEQ_AT_ZERO"/> to make the duration start at zero but it seemed to have no effect.<br><br><br><u><b>ALEG from SIP UA to FREESWITCH</b></u><br>
