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

             Summary: r-uri not being set based on the contact from 200ok
                 Key: ASTERISK-24110
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-24110
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
    Affects Versions: 12.4.0
            Reporter: Zane Conkle


In later versions since 12.0.0 something got changed to where the r-uri is no longer being set to the contact field. I have provided examples from 12.0.0 as well as 12.4.0

Below is the relevant part of 200ok then the ack from asterisk. See contact URI in 200ok -- it should be then as r-uri in ACK. However, the ack comes with the IP of kamailio instead of ip of the callee. Now, with parallel forking is no longer possible because the ACK cannot be forked.
 
So asterisk should preserve the URI from contact and use it in ACK (and the other requests within dialog that will follow -- e.g., re-INVITEs, BYE).
