Does anyone know the specifics of getting the Shoretel softphone working through a firewall VPN?
We have Sonicwall 3600 Pro Enhanced firewall with standard VPN (not SSL). We have Shoretel SG-50V and SG-90 switches. ShoreWare Director running build 15.21.3903.0
At home users have their own firewalls (Linksys or others) and they can do all other things on our network using the VPN software. The shoretel switch and other items are all on the same subnet (small office). But it cannot connect. If you bring the same laptop inside the network, it can work just fine. In both cases it is trying to access the switch by IP address (internal LAN one).
Are there certain settings in Shoretel's switches, our corporate firewall, or the home user's firewall that need to be set? I've tried looking at the admin guides but found them unhelpful in resolving this issue.
