at the office we have a VOIP system and a VOIP server.
One of the users needs to work from home and wants to have their phone.
The phone vendor tells me that if I setup the IPphone with the IP of the office wan, it will , from behind the remote location router, connect to the office voip system and work (need to forward some ports).
I do not see how this could possibly work as the phone will be behind a router and not even on the local network. And even if it did somehow work, there would be an IP conflict. Plus that wan IP is owned by a totally different ISP than what the home user has.
Anyone have any insights on this??
Best I can think is that it would likely work if had a VPN setup. Think a simple PPTP VPN would be good for this?
This is an Altigen system and Altigen phones.
