Hi
I was trying to implement a Registration server for SIP.. I had the
following doubts about the the ttl (expire time)
* When we need to delete some registration from the server, do we check if
we have to delete just the per-contact information (after it crosses its
ttl) or the entire user information . If the second case applies, what
happens if the Expire ttl is lesser that some contact ttl, we still
delete all information about the user??
* Is it an error to get a REGISTER request with no contact headers?
* What if for a particulat contact the expire time is not specefied. Do we
use the time from the Expire header (or if the Expire header is not there,
the DEFAUKT ttl)
Thanx
