What signalling protocol will you use to connect to the legacy PBX and how much work are you prepard to do yourself? It's critical that you get exact information on your legacy PBX signalling


- R1

- R2


- AT&T


- SS7



In general - FreeSWITCH can do it with a medium PC and a 4 x T1 card from Sangoma etc. The cost for a 4xT1 solution will be significantly cheaper than anything than a so-called plug & play box.
