__Redirection__: basically a way for a user on a dynamic [IP] address to be assigned a well-known name. You can register an account with a remote SIP server and when you are online, this server will tell incoming calls your real IP address. It also means you can take your hardware VoIP phone with you and plug it in anywhere (assuming you get assigned a routable IP address). |

If you are having troubles configuring your SIP phone. Try using IP addresses for everything, instead of domain names. SIP phones sometimes try to use [SRV] records to configure itself, however if it's an IP address it'll just do it all itself. |
