Hello All,

I am learning SIP protocol and I have couple of questions. Could you please
take a look at these questions?

1. How c-seq count is used by UAS to determine out of sequence request
2. How registration can be removed with a Retry-After header
3. Use of rport and received parameter used in the via header field
4. Difference between loose routing and strict routing
5. Use of q parameter in the contact header field

Thanks in advance!!

-  Alex
