>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Core/Channels, Resources/res_pjsip
>    Affects Versions: 12.6.0, 13.0.0-beta2
>            Reporter: Matt Jordan
>         Attachments: codecs_log.txt
>
>
> Given the following codec configuration in {{res_pjsip}}:
> {noformat}
> allow=!all,g722,ulaw,h263,h264
> {noformat}
> And two endpoints that support the following codecs:
> * 1010 - ulaw,h264
> * 2001 - g722,h264
> Asterisk incorrectly sets the native format on the channel to h264. This causes WARNING statements as the channel core scrambles to set the native formats to valid audio codecs (g722 on one leg, ulaw on the other):

> Generally, we should be setting up the formats correctly on the channel before getting RTP that corrects our issues.
