Now you really confused me. The way I have it setup now is that I have a VPN Router at my office and a VPN Router at home, this way I can have my IP phone connect to the main system at my office.

Do I not need a VPN Router at each remote location?

The original question I want to know is say I am traveling and want to take the IP Phone with me, what is the easiest way to have it hooked up to my office system? And if VPN is required can I hook it up to my laptop somehow?

Thank you for your response.
