Hi All,

I am new to voip, and trying to wrap my head around it. I have 2 x SPA2012 cisco phone adapters that i'm trying to connect through a VPN.
I have 2 analog PABX systems that im trying to connect through the VPN. Site A and B have a stable VPN between them.

Site A. spa2102 is set to bridge mode with static IP: 192.168.0.20

Site B. spa2102 is set to bridge mode with static IP: 192.168.1.20

I can ping both routers from either site.
I have plugged in a trunk line from the pabx to the spa2102 router on line 1 on both sites.

My question is: Can this work without sip accounts through the vpn. If yes, what steps do I need to follow?
