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.

Thanks,
Kevin L.
