I've been tasked with designing a VoIP solution in order to support a small (3 phone) hotline setup with ability to ring all phones at once and the choice to be able to ring each phone individually if desired.
IE: Office 1 picks up their handset and it auto rings to office 2 and office 3 (I believe PLAR is the term used) with the option of hitting a button to ring office 2 without ringing office 3.
From what I've read/researched this would be possible with the following combination:
3x SPA504G connected to a ESW-520-8P with a UC560 attached, all managed by a Win7 workstation running CCA.
I have experience with router and switch configs but none in regards to VoIP, but I do understand the basic concepts.
My question is, is this possible with the equipment listed? If not, what would be needed instead. Also, any suggestions on alternative equipment as I am pretty sure I am going a little overboard with the design.
