I have a client that has a small call center with about 25 computers, at any given time 15-20 people are making voip calls (both in desktop and voip phones). during peak times the network slows down to a crawl and many calls are dropped. They have comcast business gateway (250/30 plan I believe) in bridge mode connected to one netgear ROUTER (R6400). 1 port of the router goes to a server (domain controller, that assigns DHCP and DNS). 1 port of router connected to a 24 port unmanaged tplink gigabit router and from the switch to the different wiring in the office. what can be the bottleneck in this scenario?!?! I was thinking maybe they need to upgrade the switch to a managed switch?
