SIP URI
From VoIP.ms Wiki
A SIP URI is the SIP addressing schema to call another person via SIP. In other words, a SIP URI is a user's SIP phone number. The SIP URI resembles an e-mail address and is written in the following format: x@y:port (x=Username, y=host|domain|IP)
Example: johnsmith@my-uri.com
We have 2 instances of use for SIP URI's, one is to send calls to an external SIP URI, via your DID number, the other is to receive calls via SIP URI, we can achieve this using our DID number or an internal extension from a sub account.

Send calls to a en external SIP URI address
You can route incoming calls to your DID numbers using a SIP URI address from other companies. You will need to create a string like youraccount@yourip to which you can route the DID(s).
Make sure the other company or provider supports the use of SIP URI
To make a SIP URI that can be used with multiple DIDs, use the {DID} tag. The {DID} expression will be replaced automatically by the DID number as it is listed in the "Manage DID section".
Example: 1{DID}@Your_IP_address = 12143221234@128.144.122.12
Receiving incoming calls from a SIP URI
Using your DID number
You can receive SIP URI calls using the following format {Number}@sip.voip.ms, this can be used with your local US and Canada numbers, so they can be reached from outside.
Using your sub account internal extension
When you assign an internal extension for a sub account, it can also be used as an external SIP URI. For example, if your extension is 2, you could be reached directly via SIP from another network with a URI like this: 1000002@houston.voip.ms
(Replace houston.voip.ms by the server you are registered to, 100000 by your account ID and the 2 by your internal extension).
