Hello Experts, I have a new client who purchased and implemented an IP phone system. We have about 15 phones and 8 lines.
We are have strange issues such as not being able to transfer calls, calls on hold get lost, people calling in can't hear us, we can't hear people calling in, we get a fast busy when we call out, and cannot.
Our internet speeds are 27 down, 7 up. The provider has performed tracert and ping test and they tend to believe the system communications is ok.
Can anyone suggest what tool I could put in place to determine if it is a network issue (WAN or LAN) to help debug. I can load wireshark to a system and have it listen on the network, etc.. but not sure if this would actually help me isolate if it is a network issue.
