    [ https://issues.asterisk.org/jira/browse/ASTERISK-17219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=225412#comment-225412 ] 

Matt Jordan commented on ASTERISK-17219:
----------------------------------------

Reading back through the issue and then through the RFCs, this is indeed an issue with {{res_rtp_asterisk}} - that is, we don't support RTP/RTCP multiplexing.

Which, of course, we don't. Supporting that, however, is a feature request/improvement, and not a bug.

Since this issue was with {{chan_gtalk}} (which is dead), and the rest of this appears to be an improvement request, I'm going to close this out as "Won't Fix." If, of course, we end up making some major improvements to {{res_rtp_asterisk}}, we should attempt to support multiplexing of RTP/RTCP.
