I haven't used this device for an extended period, but since there are no mechanical parts, I expect that it will last. We have been using a professional on hold service for many years at about $60/month. The box that the professional company gave us sounded great when customers would call from a Lan Line. But, when calling from cell phone the voice messages were lower volume and the music would sound horrible. Music keeps cutting in and out and sounds very staticky. So we decided to save some $ and cancel our subscription and buy this unit. We are using the default music and voice messages that came preloaded instead of doing our own music and messages.

Besides that, its a music player that goes full screen on landscape mode and has a funny sound board. I made a toggle button that hangs so you can use it for hold music during a call. Thus, whenever someone puts you on hold just hit the hovering musical note and start playing music. Or play music while someones on the phone with you. On most phones you cant share the audio. After installing the application you will notice a rainbow decorated musical note hovering in the right hand corner of your Android device. By clicking the musical note you will always be delivered to the phone music media player. Here you may choose any of your already loaded music, video or ringtones. Thus, if you want to play music/video while on a phone call, simply press on the musical note. When inside the media player the symbol will change to a telephone, this hovering telephone when pressed will return you to the call screen and mute the audio. If you do not like the button hovering above, simply hold it down for a few seconds and it will disappear until a call begins again. In addition to audio and video, the program comes loaded with a humorous soundboard with 30 effects. https://play.google.com/store/apps/details?id=org.jefferyemanuel.phonemusic&hl=en.
