Currently I do everything LAN side using an analog phone. Which means I am tied to a desk. I want to break away from this constraint and have the ability to be mobile. First, I'll have to figure out how to configure a PBX for call forwarding, and I need to keep the reliability and quality of the analog phone. Most VoIP or cellular providers are out of the question for this. Next I'll have to find a portable system running Windows in order to connect to hyper-v clients. I'll also need a reliable data connection for this these issues are where I need some expert advice.
What device would best suit these needs? Most everything will be via cloud computing through a VPN.
What cellular data provider would work best for this if it even possible? I may just suck down bandwidth in this scenario, I don't know.
Thoughts, opinions, etc?
