Question : Configure all phones to ring for main line on Cisco UC520 system

We've just configured a Cisco UC520 system with 12 7940 phones at our new office, and are trying to get them all to ring on incoming calls to the main number.  Does anyone know how to do this?  Thanks!

Answer : Configure all phones to ring for main line on Cisco UC520 system

You should be able to set them all up in a hunt group and set the hunt group to ring all group phones at once.
Use the main number as the pilot number for the hunt group
Else set all phones with a "share" extension of the main number. All phones that share the same number should all ring at same time.
