             Summary: RTP not modified when UAS responds with an OK(200) with other ptime then 20ms
                 Key: ASTERISK-20835
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-20835
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
    Affects Versions: 10.11.0
            Reporter: Paolo Compagnini
            Severity: Minor


my Asterisk 10 svn recievs an INVITE from A with ptime:20 and invites B also with ptime:20.
now B sends an OK with ptime:30. The OK from Asterisk to A contains ptime:20.
But now the RTP stream from asterisk to A is the same as from B to asterisk. That means asterisk doesn't change the stream ( 20 40 20 40 20 40 )and is transmitting with a ptime of 30ms (30 30 30 30 30 ).
regarding the RFC this shouldn't be an issiue since the ptime may change during the session.
but this can lead to strange behaviour of A like synchronisations problems.
