Hi all, I would like to asking you
Hi, it's just better to keep the thread in the maillist.
about the Time-stamp header in SIP messages, and why this header does not supported in most open SIP servers, Is it recommended or not?
Is this fact true ?? I think The problem is that both UAS and UAC must have the same system time to generate a useful result. So therefore both or all SIP devices (think about an intermediate proxy) must have NTP activated.
That's not true. 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.
