[VoIP] Another WE question

>I don't know how I'd use [a 3568], with it being four-wire

It had a normal network, so it's a simple matter of connecting the
two wires from the receiver to their normal place on the network.

With all this talk of sixteen button keypads, I wanted to make sure
that my DTMF test (which is on CNET at 1-263-6602) would handle
them correctly.  I had always assumed that SayDigits, which knows
how to do 0-9 and * and #, could also do ABCD.  Turns out that's
not the case, but even if it had been, I had recently changed
the test to use Background so that the test could accept the
next digit a bit faster, before going back to the tone.

Here's the necessary magic statement:

exten =>
 _[ABCD],n,Background(letters/${EVAL(abcd):${MATH(0x${EXTEN}-10,int)}:1})
