I always used an 8 ohm to 1000 ohm audio transformer from Radio Shack, hopefully they still carry them or you can get one from another electronics shop.
Anything close to 600 ohms will work fine, 8 to 600, 8 to 1000, probably 8 to 2000. On the Radio shack one, there are (I believe) two leads on the 8 ohm side and that goes to the to the MP3 player with a 3.5 mm plug and there are (I believe) three wires on the 1000 ohm side and you use the outside wires to connect to the Toshiba.
You want an AUDIO TRANSFORMER, it will be the size of your thumb.
Why are you whining about the Caller ID? Again, the CID information comes AFTER the first ring. That is the national standard for the WHOLE WORLD. That has nothing to do with the Toshiba CTX not being perfect. It is doing exactly what is required.
Maybe for a few million dollars you can buy your own 5e switch and have your technicians send the caller ID before the first ring, then hire Toshiba to write new software so your home phone system can get caller id before the first ring. You will get national coverage in all the telecom magazines. You will be famous, so long as you are rich enough to buy the switch.
Remember, you want to play nice soft music on hold, not HARD HARD ROCK AT FULL VOLUME.
