             Summary: Pjsip rewrite port in from/to headers on reply
                 Key: ASTERISK-28287
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28287
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_pjsip
    Affects Versions: 16.0.0
         Environment: CentOS Linux release 7.5.1804 (Core)
Asterisk 16.0.0
PJPROJECT version currently running against: 2.7.2
            Reporter: Aleksandr Khomutov
            Severity: Minor


Hello! I have problems configuring chan_pjsip. In response to requests from my softswitch, the asterisk rewrites the headers from and to the port, removes the port from there. Tell me how to make it so that the asterisk does not do this? This problem is not observed for the chan_sip driver.
