------------------------------------

             Summary: Asterisk 18 does not progress calls due to codec negotiation after upgrading from Asterisk 16
                 Key: ASTERISK-29109
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29109
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_pjsip
    Affects Versions: 18.0.0
         Environment: CentOS 7
            Reporter: Ross Beer
            Severity: Minor


If you have a phone using an endpoint only allowing 'g722' and attempt a call to a second endpoint (trunk) that has 'alaw, g722' but the far end answering the call only supports 'alaw' the call ends with '488 Unsupported Media Type'.

This is due to the outgoing SIP packet only contains one codec, 'g722', which is the common codec between the phones endpoint configuration and the trunk endpoint configuration.

{noformat}
[phone]
disallow=all
allow=g722

[trunk]
disallow=all
allow=alaw,g722
