Two phones same voicemail and both notifying new msgs

Hello everybody,

hope u guys are doing great.

I need to know if it’s possible and how to set up two phones with the same voicemail and both flashing when a new msg arrives. I’m using polycom (ip phones 501) and Asterisk@home. there’s a posting that explain this, but some conf files are different because of AMP. Have you guys done something like this?

Thanks a lot
