Can some one help me wire a tascam DR-10x to a landline to create a voicemail message recorder. Complete newbie.

Basically what I'm wanting to do is make a "Audio guestbook" in the form of a modern rotary telephone.

It's to record messages at events instead of the traditional signed guest book. People pickup the hand piece and leave a message after the beep.

I am wanting to retrofit a phone into a voice message device.

If anyone would be whiling to help me. I would be so grateful. And obviously pay for your time.
