Hi

We have a site using a 3300v with an Avaya IP Office PBX. We have another site with a 2910 with a Avaya IP Phone and have no issues with the connection.

Another site runs a Site to Site VPN between the 3300v and the VigorPro 5510, on this site we have one Avaya IP Phone which will regularly just 'cut-off' requiring a reboot. We have switched out the phone but it appears to be a problem with the connection. We have setup QOS with no luck.

Any advice would be much appreciated.

Thanks
B
