[asterisk-bugs] [JIRA] (ASTERISK-23251) chan_sip - RTP Packetization set in general section not applied when Dialing direct to a SIP URI

[Jarrod Sears (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-23251?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=215430#comment-215430 ] 

Jarrod Sears commented on ASTERISK-23251:
-----------------------------------------

Retesting with the Dial command properly using the SIP peer resulted in g729:60 being used.

It is only when dialing directly to an IP address that the codec is not set correctly the the "allow=g729:60" that is in the general section.

> [Edit by Rusty]
> Issue is easily reproduced by Dialing or originating calls to any SIP URI, where RTP packetization is specified for a codec allowed in the general section of sip.conf. The codec specified will be used, but the packetization will not be applied. It may happen with peers as well, but I was unable to reproduce it there.
> [End edit]
> Incoming calls to the server correctly negotiate to g729:60.
> The sip.conf is set to:
> disallow=all
> allow=g729:60
> The outbound leg of the server then sends a SIP invite out specifying g729:20.
> I've tried setting up specific SIP peers and also using the general codec settings, both experience the same issue.
> I have also tried using the SET(SIP_CODEC=G729:60) command, which does not work.
> I have tried using the a server with Digium's g729 codec. I've also tried on a server without a g729 codec. Both experience the same issue.
> I originally experienced the issue on the 1.8.11.1 (Asterisk 1.8.11-cert1) version that we are using generally for production. I recently installed a new copy of Asterisk 11.7.0 and have the same problem.
