> This is similar to ASTERISK-23721; but on asterisk 13.1.0.
> Attached pjsip.conf
> To reproduce the bug:
>    - Run watch -n1 "netstat -lp | grep aster"
>    - Make a call using sip client (which don't support g729)
>    - You will get messasge "No joint capabilities for 'audio' media stream between our configuration((g729)) and incoming SDP((ulaw|gsm|alaw))"
>    - Check netstat result; you will find 2 RTP ports opened and not closed.
>    - Allow ulaw; make same call from same sip client
>   - ports will be opened for the call duration and then removed after hangup.
