I have a client with a SPA8000 latest firmware version having the following issues.
This is a first time implementacion, and he is registering to his own PBX IWATSU.
He also has a VPN tunnel from a remote location to where the PBX is at. When the remote
site makes a call the remote location can hear the client but he cannot hear them.
The registracion problem happens on ports 3-4 and port 5-8 register but they loose registration
consistently at random intervals. Ports 1 and 2 work just fine as far as registration goes.
On the interface port one and two have a Map Natting Enable setting that the client has set to
no, but on the other ports that option is grayed out and they are all set on yes.
Any hits as to what could be the issue? I welcome any pointing in the right direction, or advice
Thanks in advance.
