Some ham friends of mine have these devices and they work great for just the thing you want to do.

An interesting exercise is to "sweep" your audio path by doing various
tones and see if your repeater's audio path has a "slope" to it.

Certain to-remain-un-named controllers are rumored to have an
inappropriate value published in their RC circuit for de-emphasizing
audio if they're being fed by a discriminator.

1 KHz is the "usual" test point, but there's nothing stopping someone
from setting 1 KHz to whatever deviation their controller/repeater
manufacturer recommends and then measuring and plotting 440 Hz, 800 Hz,
1200 Hz, 1800 Hz, 2200 Hz, etc.

Sometimes you find out why your repeater sounds "funny", doing
experiments like that. :-) Link radios -- you can do the same thing.

If your CAT-1000 controller has a regular autopatch on it, something
like this might be useful:

http://www.phonelabs.com/prd05.asp

There are a few companies making these, and they're popular in Europe
where many people don't bother having a land-line phone anymore -- they
just drop the cell in one of these when they get home.

Never tried it myself, but looks like it would work fine, if the cell
coverage is good at your repeater site.

There is no reason that you can't link a phone line into your repeater.
Besides it saves paying an additional cellphone bill:


Or if you do want a commercial product, you
will have to dedicate a cellphone to it:


A friend of mine has one with the bluetooth adapter.
When he arrives at home he simply plugs the cellphone
into the charger and lays it next to the unit. The cellphone
appears as line #3 on every phone in the house. He is
forced into using this device since the cellphone coverage
sucks in his neighborhood - the front bedroom on the
second floor is the only place he can receive or make
a call.
