You can network two MICS together as noted above or by using E&M cards to an E&M port on a network VoIP mux. Micom is one source. Unfortunately the CICS will not give you much for networking; no T1 card, no E&M card. but by being creative you could set up one or two analog VOIP channels (when either end closes the loop it would send a ring to the other end) as CO lines into a CICS; set up DISA answering on both ends and then when one end initiated a call the voip circuitry on the other end would answer with dial tone, then the originator would just dial the extension. Note: you would need Combo cartridges in both ends to provide dial tone out. JerryReeve
