You are correct. I confirmed today that Verizon's analog PBX trunk with
20 DID's would be receive only.
What exactly would I be asking my Telco for, as far as service, if I
were to go the DTMF route? Are there any pro's or con's for DID vs DTMF
other than the cost of hardware? IE, some functionality, etc.
