[VoIP] Dial Pulse converter specifications

[john jones]

Since so many VoIP ATA's don't support DP dialing,
there has been a suggestion to construct a TT to DP
converter.

I'd like to start collecting specifications of what
this device needs to do.

I expect that on the FXS side, it ought to perform in
ways similar to the teltone converters often installed
between Linefinders and the 1st selector although I
imagine that more loop supervision is required.

Let's get a dialog going on this.

Thanks!

John
