Hello, Is valid for an UAC to accept a 200OK coming from the UAS with a To- tag different than received in the previous 180?. This is the scenario:
An INVITE is sent from an UAC to a proxy. The proxy proxies the INVITE to the UAS. The UAS sends a 100 and 180 to the proxy, which are resent to the UAC. The UAS does not "answer" the INVITE and the proxy times out the transaction. After that, the proxy (via CPL) sends the INVITE to another UAS which replies immediately with a 200OK that is proxied to the UAC. The UAC does not accept the 200OK because the To-tag it received in the 180 from the first UAS is different of the To-Tag received in the 200OK from the second UAS. Is this a valid behaviour or should the UAC accept the 200OK and update the internal "early dialog" state to a confirmed dialog using the To-tag of the 200OK sent by the second UAS?. Thanks.
