Can anyone recommend a MOH Device I can propose for a customer (Pizza Shop) who wants to create there own advertisement's or possibly a third party


let me know

Thanks

Which NEC system? The SL1100 doesn't require an external MOH player, you can install it directly to the system. Otherwise, there are several devices you can propose - I use a USB MP3 player that reads the MP3 file from a flash drive you plug into the unit - very easy to update ads.

OHP 8000 will do it
