I think The problem is that both UAS and UAC must have > the same system time to generate a useful result.

The request can contain a header like: TimeStamp: 25 and the proxy/server replies in the 100 Trying: TimeStamp: 25 0.001 This means that it has token 0.001 seconds to the server in order to process the request and generate the 100 response. -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
