KX-T: Call In to hear audio program

Hi Jeff,

I've contemplated and work a few related ideas.
We put audio on the system for in-house extensions to be able to
monitor services.
Connecting from the outside first appeared troublesome because of the
limitation of the number of lines.

Now there are free conference call services that can help with that.
If you interface the audio to one slt extension, that extension can be
used to call into the conference circuit, then callers just need to
know how to access the conference line.

www.freeconferencecall.com is one I have used  before. Be sure to
learn how to use the moderator features. Calls can be set up as a
"broadcast" so that callers do not interupt the audio.

we used a simple Symetrix audio interface (that has been since
discontinued) but you can use a variety of types, many available on
ebay for cheap. I liked the Symetrix unit as it has simple front
controls- power, audio level, and one button to switch the call from
your slt, to the audio input.

There are devices that allow callers to call in and be connected as
well. I will have to check names/numbers later. One location we got a
rackmount unit that allowed multiple lines to connect, again this was
more for internal calls than outside. One issue was that calls were
not disconnecting properly if the caller hung up (the internal calls
did not provide the cpc signal).

Again, the big issue with this is how many callers can be supported.
If only four people call in, you are investing in 4 co lines to be
used. Now either they will tie up the existing lines during the
service, or you would have to pay for more co lines that will only be
used once or twice a week.

Internet web-cast is another option, but many times the elderly would
not be able to access this easily.
