I would be a great addition to my obi to play music on hold. You can find this feature on any business pbx or phone system, and I don't think the obi is too far off from being capable to play Mp3, wav, or ogg files.
A MOH feature would allow business to play their advertisements, or notifications while someone is on hold. The music files could be made available through a few options:
-Over a internal network via media server.
-By uploading a song file to
obitalk.com (FTP)
-upload file to the obi itself.
This feature could then be rolled out as a firmware update to the obi 110 and 202. Music on hold is a much needed feature IMO the obi needs. Especially if it is being marketed to businesses.
