You should be able to check half of it fairly easily. Connect it to your
PC, bring up your favorite comms program, and tell it to dial a number.
You should be able to hear it in the telephone microphone end of the
coupler. If you cannot, either you have some wires crossed or that part
of it is dead. If OK, you may be able to devise some similar test in
reverse to test the other channel.
