[Freeswitch-users] Getting FreeSWITCH to use RTP port + 1 for RTCP

[James Mortensen]

Hello,

I've searched the list and documentation, and it's not yet clear if
FreeSWITCH is able to send candidates in the same manner as we were doing
with Asterisk 1.5 where it sends the RTCP to the RTP port +1.  In other
words, I'd see candidates that looked like this:

a=candidate:3441596188 1 udp 659136 10.3.1.1 20622 typ host generation 0
a=candidate:3441596188 1 udp 659136 50.18.X.X 20622 typ srflx generation 0
a=candidate:3441596188 2 udp 659136 10.3.1.1 20623 typ host generation 0
a=candidate:3441596188 2 udp 659136 50.18.X.X 20623 typ srflx generation 0

For instance, if the RTP port was 20622, the RTCP port would be 20623.
 We're getting no audio when trying to make Chrome to Android and Android
to Android WebRTC calls, and we thought we'd try a different RTCP method as
we did have it working with Asterisk but want to use FreeSWITCH instead.

I've checked out the latest FreeSWITCH code from the master branch.

Not sure if FreeSWITCH can do this yet, but if anyone knows that would be
helpful.

Thank you!
James
