We have a Mitel SX 200 Digital.

Last week we had a new property management system installed. We now have problems with the call accounting.

What we have now is a Prophet H-3 call accounting.

To best describe how it is.
Comming out of the Phophet H there are 2 ports, "System" and "SMDR"

SMDR has a Y cable, one to the Mitel and one to the Printer.

System has a Y cable, One to the "digi port" on the pms, the other is left open.


Now the installers tell us they can get the data when we make a phone call. But they say they need 2 way communication here. We are told we need a Data Set.

Our phone vendors told us they can order one, and will try to install it. The guy that would be doing this hasn't installed one it 10 years he said. But the cost of the Data Set seems real high. So I wanted to know what I should be looking for so we can supply the Data set.
