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

             Summary: Incorrect SDP in 200 OK when PJSIP_DTMF_MODE is used
                 Key: ASTERISK-27209
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27209
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_pjsip_session
    Affects Versions: 13.15.1
            Reporter: Torrey Searle


When PJSIP_DTMF_MODE is used to modify the dtmf mode of a not yet answered call, the SDP in the 200 OK reflects the old dtmf mode instead of the new one.

This is due the fact that an SDP answer is build at the time the SDP offer is received.  Included is a patch to enable pjsip to re-generate the SDP answer if it's legal to do so & required.
