We have a customer with an existing VPN using sonic firewalls. We put an IPO 500v2 at each location, each on their own subnet. Without any special programming, the phone systems do not see each other, and you can only ping the gateway of the opposite side from each location. I put IP routes into the IPOs and I can see both units in the manager, and on System Status, each says that the SCN is up, but when you go to make calls between systems, you get an unobtainable. The weird part is that, for a split second, you can see that the system resolved the correct extension name from the other system right before you get the UNOBTAINABLE.
Any ideas? VPN settings blocking the call?
