How to test the Internet channel for the possibility of VOIP/Skype?

Question

Skype

Skype and other VOIP operators work with big lags, the provider makes an innocent face - “there are pings, the declared speed is there - I don’t want to know anything else ...”. The provider has its own IP telephony product. I suspect that either specific shaping or packet delay is being done, which are not critical for downloading, but critical for Skype. How to bring Provo to clean water? Is there any specialized software that checks the channel for compatibility with VOIP?

Answer 1

I haven’t seen specialized software, but in order to minimally check it cuts / doesn’t - you can throw a VPN to a host outside your provider’s network (buy an inexpensive VDS or take a free trial VPN somewhere), connect VPN - log in via Skype, if it works more stable through VPN - obviously the provider cuts VOIP/Skype-packets.
Most likely, it is unlikely that it will be possible to “convict” and punish Provo in ru-realities or it will take a lot of time, so IMHO it will be easier to find another provider.

Answer 2

What is the difference between VOIP and regular IP?
If only specifically limits on some parameters.

Answer 3

I strongly recommend punishing such a provider with a ruble ... one in the field is not a warrior, but doing nothing is also not an option.
After you check the work of Skype through vpn, when you terminate the contract with them, you will be asked the reason (preferably answer in writing) that you are leaving due to forced disruption of voip applications such as skype by the provider.
The operator will make big eyes and call you a lamer, do not believe it, he may simply not be aware of it. But the fact that a client leaves for this reason can give a lot, the main thing is that it be documented.

Answer 4

Your contract with the provider should specify the minimum connection parameters (delays, jitter). You just need to try iperf from you to some other computer, generating traffic similar to Skype or telephone ones. Here you will find out whether the service satisfies the terms of the contract or not.

Answer 5

Traffic is traffic. Take four, see what packets are being transmitted (size, protocol, traffic width, other options) and generate the same one. And then the experiment: the second point can be connected to your provider, then to the one that has peering (tracert will help you determine)
