I am using an Asterisk server installed in an Ubuntu server in an Amazon cloud. Sometimes I am having problems with the quality of calls, is cuttings, I think that this problem happen because the network of the client or the server is busy. How I can check it?
I want to know about routers of specific networks that uses voip, do you recomend to use it? What models recomend to me use in a wireless and cable(4 ports, can use switch to more) network until 12 devices.
