You really be asking what these ITSP want/support.

But the answer will either be:
- REGISTER to receive calls, see:
  http://blog.miconda.eu/2010/10/best-of-new-in-kamailio-310-10.html
- accept some certain IPs to send INVITEs
  TIMTOWTDI, one of them is the dispatcher module with seperate ids per
  ITSP and ds_is_from_list to accept from them.
