You could blame on your VRS provider all you want, and it will be moot point after all. Once your ISP connects your VP to outside of their network, it goes though series of network segments and if these segments gets messed up before reaching to other end of your VP call, ISP do not have control over them which is sucks! Hence never reached at Sorenson DNS, which never reached the 10 digit local nbr server in order to be able to get connect outside of Sorenson network.Īll VP acts as an endpoint that is it, ISP is the one that makes first connection outside of your network. When you make a call, first your VP looks for DNS, when DNS redirect, usually at the first router to the modem, Modem search DNS again, it goes to ISP, if their ARPnet table is not formatted correctly, for instance duplicate entries, they would think it is within ISP network and try to redirect within ISP network instead of outside of their (local ISP) network where actually the person you are calling is actually outside of your ISP, it gets lost. Hence on why router, modem, VP rebooting is necessary.

Sorenson, or any VRS providers do NOT control the Internet, often it is local ISP that controls the gateway, if they upgrade their DNS server, ARPnet server usually that is what causing problems.
