Hi Jeff,

I typically do this with streaming audio via internet.  A decent quality feed
that will work over dialup connections is not too difficult.  Contact me
off-list for more details (as I have multiple servers that handle this kind of

The way I would do it in telephone land would be to rig up a circuit that
would connect an isolation transformer to the line with the contacts of a
slow-to-release relay.  The coil of this relay would get fed by two things: a
ring detector relay, and a current sense relay.  So as long as you have
current flowing, it holds the circuit up.   This of course depends on the PBX
dropping the battery momentarily when the call ends.  If you can provide for a
battery reversal for answer supervision, you can insert a diode in there to
help with that.

Not sure if the KX-TD will do that though... I did accomplish the above with a
VOIP box (Sipura SPA2000) that fed INTO a KX-TD.
