Okay so my family owns a golf course. We have a few buildings that I have bridged wirelessly. We only have phone service in one of them (the club house) We would like to implement a Cisco IP phone system. Our internet will not support VOIP (they say it will but the speed and uptime is spotty) so my question is what main unit / call manager is best for us? Not going to have many phones, 6 or a couple more. For now I want to use this system on our analog line ONLY. IP PBX systems are a new one to me, I know Nortel in and out and I design and install IP camera systems. So I'm not totally retarded on the subject, just looking for what I need to start with. Any other advice you have is welcome. I'm all ears.
I really appreciate everyones feedback!
