My freeswitch device profile has "rfc2833-pt" set to 101 and "inbound-late-negotiation” set to true.<br class="">
<br class="">
The FS then bridges this call to a gateway, sending an INVITE offering pt 101 for 2833.<br class="">
The 200 OK on the B leg comes back (with pt 101), and FS then sends a 200 OK to the original INVITE with pt 101.<br class="">
So, to summarize, the client has offered 101 for 2833 and the FS responds with an SDP with 96.<br class="">
At that point, DTMF does not work (DTMF generated by the client not recognized by the far end gateway).<br class="">
<br class="">
Is there a configuration setting that would tell FS to use the RDC 2833 payload type from the A leg when bridging a call?<br class="">
<br class="">
Interestingly, I am only seeing this problem on servers I have upgraded (to 1.6.8) — older servers do bridge the B leg offering pt 96 if that came in on the A leg.<br class="">
(Note, though, that the older servers are also not configured to do inbound-late-negotiation).<br class="">
