So, we are going to be using a new company for our voip services and I was wondering how good is VyOS/Vyatta with voip, and what do I need to do to make sure the quality is as good as it can be?
I believe the company that is being discussed is five9 – not sure – and I need to make sure everything works smooth, because the current voip provider (telonium) seems to have issues with quality, even when running on dedicated fiber 20/20. Yet they swear it is bandwidth or configuration issues. The customer service people complain that they keep getting calls coming through, while they are on other calls – some issue with the queue. But when they call Telonium, they are told that this is due to bandwidth issues. Another issue they complain about is the fact that sometimes they can hear the customer, but the customer cannot hear them. I know this is usually a quality issue, and is likely related to bandwidth. However, we have since moved these lines to a dedicated 20/20 fiber and separated them from the rest of the network, so these problems should not exist.
I have never ran these lines through the VyOS router, because I only installed the VyOS router a week ago. Presently, I am running the fiber through an Apple Time Machine (or AirPort?), but the phones are the only thing connected to it, yet the issue with the queue persists. I don’t see any reason why configuration would affect the phones in this case, since there is no other traffic going through it but the phones. I don’t think I need to prioritize voip when voip is the only traffic, right?
Anyway, my main concern now is the configuration of my VyOS router, because I will have to run everything through VyOS now that they plan on using five9, a cloud based service. Is there anything in particular I need to look at? Like a reference guide? Is there an option to simply optimize all voip traffic (as a service type), rather than having to prioritize specific ports?
