Music on Hold Phone System




About: Music, chemistry, electronics, etc.

I was inspired by the Automated Answering System Instructable ( to create my own call on hold system. This is a very simple hack, and allows me to make people listen to music before I talk to them.

To make my hold system, I opened the phone, removed the jack that connected the base to the handset, and replaced the input and output lines with two mono jacks. I also rewired the ringer switch to turn the set on and off so I wouldn't have to continue to use the handset for this purpose. To use the system I just answer my regular phone, tell the person they will be put on hold, and turn the hacked phone on. Then I turn on the hold music from my iPod, hang up the phone I used to answer the call, and go about my business until I'm ready to talk to people.

I originally meant this to be an Instructable, but I didn't document it because of camera troubles. If you are going to attempt to build this yourself, feel free to ask me any questions.

    It is not advisable to connect an ipod to the direct telco line(the one that plugs into the wall) because that line can cary high voltage, the base of the phone contains circuitry that converts the telco line in to (audio) line voltage, your most likely senario is that the iPod was connected to the telco line, and when the phone rang, your iPod got hit with 90 Volts AC, (which is not good) WARNING: Phones that have the keypad and hook button on the handset CANNOT BE used for this intractable in this method. one method to confirm that your phone can be used for this project is to dissasemble the handset and confirm that the only thing that the wires connect to are the speaker and mic. NOTE: the phone used in the photos above did have a keypad on the handset, but the phone's internals were still in the base. ANOTHER WARNING: Do NOT Do this if you are not sure where your phone's internals are.
