One of my clients has a central office with a VoIP PBX system managed by a different company. They have one branch office now. Both locations are tied together using MPLS connections. There is really no data that needs to be transfered, they do need the ability to transfer calls from the receptionist at the mail office location to the remote office by just using the remote office extention, say 401. They now are starting up a second remote office and will have a dedicated T1 plus a cable company supplied internet connection. Will they also need an additional MPLS connection at this location also to have the ability for the PBX to transfer the calls? The remote offices do not utilize any of the computer or printer resources at the main office. The VoIP provider is wanting to install the additional MPLS, but I am wanting to try and save the client the additional monthly charge for a internet connection that may not be needed. Thanks for your help and advice.
