I am looking for information on how I can design either a policy/search rule or a configuration to provide a limited amount of our external customers the ability to dial into our network via SIP. We have a VCS-E(Cluster of 2) sitting in the DMZ with traversal links to our internal VCS_C (Cluster of 2). Currently we have configured the VCSE to always 'check credentials' for any incoming jabber/MOVI/SIP call. However we would like to offer just a few of our customers the ability to call into specific conferences or SIP clients/endpoints. Our plan is to block everybody else from dialing into our network via the expressway. How do I accomplish this ?
