Server locatin decider policy

Okay, so I'm sure I'm using the wrong terms, but can someone tell me how Vonage decides which server to serve me from?

I use Charter Communications and I just switched to OpenDNS as my DNS Server. This is because Charter's DNS Servers seem to have somewhat regular issues and have always seemed a bit slow to me.

However, if Vonage selects my Voip server based on my DNS location, I'm going to get poorer service on my phone.

Thus, I'm wondering if anyone knows on what basis Vonage assigns me to a server?

I used OpenDNS with Vonage on Charter and never had a problem except when Charter had a problem. It doesn't really matter which server they serve you from as long as you have a good connection.

There are 2 types of servers. SIP which handles the actual registration and call initiation / termination signaling and RTP server which streams the audio to you.

RTP server is chosen based upon the location of the Vonage terminating GW your call goes through and on an outbound call, depending upon what number is dialed will determine it's routing. So each and every outbound you make depending upon number dialed could stream audio to you from 1 of 4 different geographical locations. On inbound calls, depending upon what market your number comes from, will determine which Inbound location streams your Inbound audio.

SIP servers are based upon a group of 4 and that is just determined randomly. You will register to 1 of the 4 which are all in 4 different locations for redundancy and over a time period could be registered to any one of them.

Doesn't OpenDNS just affect http requests? What is the Vonage adapter using to send its requests?

DNS servers will look up any hostnames for any service you need to resolve to. The term Open DNS servers just mean they are DNS servers that are not assigned to you by your ISP but still process DNS requests from clients outside of their own domain or network. Some DNS servers will only process requests from clients that are within their network and therefore are not considered Open DNS servers.

But the DNS servers you put in a router or on your PC do not change that way a Vonage adapter resolves Vonage based server hostnames for SIP and TFTP requests due to it uses the Vonage DNS servers which are provisioned into it's profile
