I have connected OS7070 and OS7200S via VPN using SPNet. When I use LAN IP TYPE: PRIVATE, both systems can call each other, there is no problem. But I want to connect ITP IP phones remotely to OS7070 using Public IP, So that I have to change LAN IP TYPE:Private & Public, Once I changed it, 2 systems can not call eachother, Showing No user response.

Please HELP!

Thanks in advance n appreciate your reply.
