What do you mean you can access the interface on both phones? Over the VPN you mean?

I think you need to take a step back and break this up into two situations:
a) Forget SIP accounts/etc for a moment. Can you get both phones to connect to VPN server and be active on the VPN at the same time? i.e. on your server you see both, you can ping both, and you can log in to both web interfaces over the VPN addresses?

b) If the above is true, then there is something else beyond the VPN that is causing the problems? Without using VPN, can you have both extensions register to your PBX at the same time (i.e. from local network does it work)?
