I need to design VOIP system on our office and I need some advice from the experts.
Basic idea is that we are going to use 10 PSTN line coming through the office, and by using the hardware we are splitting 50 lines for the VOIP phones and PCs. My question is that to setup the system like that, what kind of hardware I need to purchase and how much it will cost? Please take a look at the attachment to get better idea. It's the basic design for the system.
Thanks in advance
