I have a system, using 2 IPKII cpu software is 1.60 with PVA card service pack 3 and software 1.58. I am working on CCIS over a wirless network. The Network people are using Firebox Routers. The problem I am having is when the VPN renews the connection or the VPN is rebooted, The PVA cards do not work right away. It takes it about 7 or 8 call before you can make a call between the PVA cards. But you will see the VPN running and can ping across. If I reboot the PVA card it will work until the VPN goes down agiain. Any idea. :bang:
