I have a customer who needs an 8X16 system and voip for two off site locations, one phone each location. Seems right for an SBX-IP except she wants the voice mail to answer for two companies. The 4-port doesn't sound like the right choice. Anyone tried the pathfinder on these SBX systems yet? If so, I am assuming it has to be analog. I don't see any DTMF modules as option. Any help would be appreciated.
