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

             Summary: chan_sip returns forbidden 403, if the incoming number was determined as the present.
                 Key: ASTERISK-25648
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25648
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_sip/General
    Affects Versions: 13.6.0, 13.5.0
            Reporter: Alexey A. Astashov


I detected a problem with the call processing protocol SIP.
For example:
"Some Station" (num's 1100-1299) --> call came to my GW Asterisk with internal CID "Some Station" --> then call routed to my station Asterisk (num's 1100-1500), but last determine existing number and return Forbidden 403. 
In configuration on My station I have insecure=port,invite

The error is that if the final PBX will see that an incoming call comes CID number that it has, it sends to the gateway error 403. The error was discovered with 13 versions of Asterisk, Asterisk on 11 - everything worked well. At the same time the IAX2 protocol, this is not a problem. Unfortunately, I can not test the functionality of the protocol PJSIP.
