Cisco phone ringing external bell

[teltonman]

I have a relatively small Premier external bell. Since we recently cutover to VOIP, I have to figure out a way for the Cisco phone extension to also ring the external bell which ran off our Norstar system.

You will need to hook up an analog port (FXS) to the bell and configure it to ring the same time as the phone.

Do i still need an ata to do this or can i use the fxo card that we have the 911 lines running through in the router? There are two available ports

FXS or ATA, recommend an FXS.
