Don't know about that specific model, but I haven't ever seen a VoIP phone with a VPN tunnel support. You likely need a dedicated VPN gateways both side.

For a quick, temporary solution you can: 1. use a software VoIP client on remote computers; 2. open SIP ports from WAN, only allowing access from the remote site's public IP (if it's static).
