I have the Avaya 412 with the voip card. I have only the phone manager, configured for voip and it works with in my LAN. My problem is it will not work over the vpn, the vpn is fine I can ping everything on my network but the Avaya 412 pbx.

Is there setting in the 412 that I need change in order for it to respond to my VPN traffic?

Thanks for the help

I haven't tried an Avaya 412 over a VPN but it sounds like your issue is one of NAT traversal. If you have two sites, site A and site B, lets say you have a subnet at site A such as 10.10.1.X and at site B you have 10.10.2.X for voice,
can you ping IP phones at both sites from site A? from site B?

I can ping it with in site a but when remote i cant even pint the ip office 412 pbx. Strange because every other node is pingable on the vpn. Thanks for the responce.

This usually happens if you do not have an IP Route in the IP Office to direct traffic to your remote LAN
e.g if your office LAN is 192.168.0.x/24 and you remote LAN is 192.168.1.x/24, you will need an IP route in the IP Office to direct traffic for the remote LAN to the VPN gateway mask gateway 192.168.0.GATEWAY
DESTINATION lan1 (or maybe LAN 2 on the 412

see attached screenshot.
Sorry if this is teaching you suck eggs, but this is the usual cause.
