Re: [Serusers] rfc 3262 support

Hi Darilion Please check the following snippet from rfc-3262 "An element that can act as a proxy can also send reliable provisional responses. In this case, it acts as a UAS for purposes of that transaction. However, it MUST NOT attempt to do so for any request that contains a tag in the To field. That is, a proxy cannot generate reliable provisional responses to requests sent within the context of a dialog. Of course, unlike a UAS, when the proxy element receives a PRACK that does not match any outstanding reliable provisional response, the PRACK MUST be proxied."

Thus, ser supports PRACK as any other generic SIP request. Maybe you could fake PRACK requests or responses between a PRACK capable client and the proxy, but this will cause end-to-end CSeq mismatch and would require a dialog stateful proxy to adapt the CSeqs. regards klaus Greger V.
