We have a PIX 515E running version 7.2.1. I have (2) PIX 501s that are going to be on dynamic DSL lines. So I setup those to connect to the PIX 515 as EasyVPN clients. I then enabled traffic between two or more hosts connected to the same interface. I have used the ASDM for the configs of the VPNs as it seems quicker to do it that way. Both PIXs can connect to the 515E and make calls outside and to other non-VOIP phones. When a VOIP call is placed between the (2) phones on the DSL lines, the call rings, but as soon as you pickup the call there is no communication between the devices. The phone system tells the devices to talk directly to one another. What am I missing here? Is there something simple I need to enable? I even have both clients using a different IP pool, I have tried both ways. Please let me know if anyone has a good thought.
