Sonicwall firewall is used for the VPN, and of course, the Sonicwall people are blaming the phone system... I can't for the life of me think of a way this could be the IPO causing the issue. I do know the IPO can NOT ping the phone when it is VPN'ed but the Sonicwall can ping the phone. It is weird the phone is getting traffic from the phone without being able to ping it. I see in monitor the IPO is using port 1719 but the phone is using ports in the 49000 range... so my best guess is port 1719 is being blocked or misrouted.
If anyone has anything I can try via the IPO I will be happy to try. If anyone has run into this issue and has figured it out I would love some help here.
The truth is just an excuse for lack of imagination.
