I am looking to implement a voip setup for myself and possibly 2 others. I am looking to use the voip on my android phone (wifi and 4g) as well as 2-3 ip phones and suggestions on software hardware setup. Would you recomend a 100% dedicated PBX box or could it be implemented on a shared server. I currently own 2 HP server with dual Quad core processors and 32gb ram etc..
Also is there a specific type of hard phone you would recomend or would you go strictly with soft phone or a combination there of.
