At an office we have a Samsung PBX which about 100 numbers. It's quite small, but it's got about 20 phones connected to it.
I know that it supports SIP... So, I was thinking of getting a SIP phone for home.
We have a LAN-to-LAN VPN between some of the homes and the office.
Would it be possible to route calls from the PBX to a SIP phone over a VPN?
I dont know much about SIP
Thank you !
