      Allowing inbound calls from multiple/many IPs/Domains on a single SIP Voice Trunk.


      It is easy enough to allow/restrict SIP traffic via ACLs, however....  I have a carrier that has about 100 IPs (all in the same class C) that their SIP traffic may originate from, and their INVITEs reflect their source IP (not a domain.)  I believe that the body of the INVITES for traffic inbound toward a TA900 typically should contain the "sip-server," but in this case that could be one of 100+ IPs.  How can we get the TA900 to allow inbound traffic from any of their 100+ trusted IPs?
