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

             Summary: Incorrect off-hold on ReINVITE via Replaces
                 Key: ASTERISK-29273
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29273
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Bridges/bridge_holding, Bridges/bridge_softmix
    Affects Versions: 16.16.0, 13.38.0
         Environment: CentOS 7
            Reporter: Igor Olhovskiy
            Severity: Major


When the call is off-hold via ReINVITE with Replaces, media is not being established back correctly.
SIP Client A - Asterisk - SIP Client B

SIP Client A calls Asterisk and Asterisk bridges it to SIP Client B.
SIP Client B puts Client A on hold (a=sendonly), Client A listens to MoH. All ok.
Then client B makes internal transfers (it's PBX) and reINVITE's Asterisk with Out-of dialog ReINVITE with Replaces header.

Client A still hearing Music On Hold, but what Client A said, is being heard by Client B. But what Client B is said, cannot be heard by Side A.
