Technically you "might" be able to do this but it would be a really bad idea.  Why would you want to span Layer 2 across like that?  Just create a new network (ie - at your remote location and route across the VPN.  But then you need to ask yourself, "do I really want VOIP traffic traveling over VPN?".  Is this a dedicated MPLS circuit that has guaranteed delivery and QOS?  Also, the answer here is probably no.  In this case you may want to look into a cloud service for managing these remote phones for the best user experience.
