We have 2 locations in US and 2 offices in 2 other countries. We are currently on an MPLS network between our 2 US locations, which handles data/VoIP. I'm wondering if we should stay with MPLS or go with basic internet access(BIA) and build VPN's between to handle our data/VoIP traffic.
Hub office has the most phones 55 and the remote range from 3 to 15 phones per locations, so not a lot of bandwidth eaten up by voice. Data between the offices will not be overwhelming, just some source code transferred in the evening from the other country locations.
Trying to way out the pros/cons of each, basically.
