Our office uses and RV082 and recently installed an IPECS PBX system with VoIP support. We have a one-to-one NAT set up to allow access from outside to the IPECS shelf that works fine. When we hook an IP phone at a remote location the IPECS system sees the phone and assigns it an IP but the phone itself will not come up. We tested the same phone against another office and different router and the phone came up fine, so it's not the phone. We went as far as dropping the firewall to check against the settings but the phone still didn't come up. The RV082 doesn't have any settings directly related to H323, so we're at a loss as what needs to be tweaked to get the phone up and working. We've looked in forums but haven't found a solution. Anyone run across/resolve this before?
