Hi,
We are running an Avaya IP office system. We have VoIP working on LAN, WAN and via VPN connections.
However -- how do we get this working (from an Avaya IP handset) over simply the Internet?
The Avaya sits on the LAN obviously.
1) - Would we configure a default gateway to be the firewall? - Have a 1-2-1 NAT rule of one of our external IPs to the Avaya? - Configure the handset to talk with the externa lP? Q - Would this work? Q - Is the Avaya secure if all ports are accessible from web?
Any idea welcome on this -- as we are getting a bit of heat over this!
Cheers.
