so, maybe the pcscf_is_registered() function could:
* retrieve the pcontact record in O(1) using the Contact URI hash
[should pcscf_is_registered() fail if no there is no Contact
header? Could the Contact URI somehow change between REGISTER and
other requests?]
* compare the request's source ip & port with those stored in the
pcontact record
* if both steps succeed, return true
This should prevent performances issues if a lot of contacts are
registered. Besides, this would allow to differentiate several UACs
using the same network connection (as they very likely would provide
different contact URIs).
What do you think of this?
Cheers,
