.....play a recorded message/music until the phone is answered.

Could someone please point me in the direction of a bare bones product that could do this. I have been searching all day and I cant find something like this.

The closest I came was this https://www.ebay.com/itm/NEW-CYGNIO..._DefaultDomain_0&hash=item20ad2df5aa

but it is in America and they dont ship to europe and I dont know if it will work in europe.

I know phone systems do this but I dont need all the features just the auto answer with a greeting.

I have an ISDN line but the NT works with ISDN and analog phones

If someone could help me it would be appreciated
