[asterisk-bugs] [JIRA] (ASTERISK-23082) Including g722 in pjsip codec configuration results in unexpected SDP offers

[Joshua Colp (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-23082?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=213578#comment-213578 ] 

Joshua Colp commented on ASTERISK-23082:
----------------------------------------

So, the reason this occurs:

When setting up an outgoing leg the code internally can request formats. There is some code which, under some circumstances, determines that a single audio codec is "preferred" and passes this on to the outgoing channel driver. In the case of chan_sip this is effectively a suggestion that it be put into the list. In the case of chan_pjsip it seems that the code *only* uses the requested audio format, therefore dropping all the rest.

This is a valid issue and spending any time further isolating the behavior of chan_pjsip is unwarranted. We should confirm the behavior of chan_sip and duplicate it in chan_pjsip. IMO.
