Hello every one, I give you a picture of the my client network.



I have two building with a wireless link between.

I have VoIP in the right side of the picture, but the VoIP does not go over internet, is only for internal and for the phone system.

The network 192.168.1.0 talk with 192.168.3.0 and 192.168.3.0 talk with 192.168.1.0.

My wireless link is 100 Mbps

The VoIP phone work for two month with no problem.

Now, the phone cut approximately two a tree time per day. All phone cut in the same time and to pickup the phone call after the cut, the client put the call on hold.

I'm sure that I have no problem with phone system.
With wireshark I see a lot of NetBIOS, ARP and broadcast.

Do you know what could cause this is cut or what I could test.

In addition, I am unable to cause cuts.

Thank you
