Got a site running 20 local phones and 20 remote phones. Been having problems mainly with Remotes. Narrowing issues down to possible router (settings) issues (not controlled by me). I Am trying to get ESI stuff on their own network. The only drawback is they are connecting PCs through the Local phones. I am wondering if two IVCs could be on separate networks so I could isolate the remotes to their own router with its own WAN connection.
