Client Registration

A

All client stations served by the SPA9000 must register to the SPA9000, which does not allow a station to make calls unless it is registered. If the client station is configured with Station Name, it should include a P-STATION-NAME header in the REGISTER request. Following is an example where User-A has been assigned a primary extension of 5031.

In this example, User-A shares a line appearance with User-B, whose primary extension is 5041. Extension 2 on the User-A station must then be set up the same way as Extension 1 (User-A primary extension), but with the <Shared User ID> parameter set to 5041. The User-A station then performs a third-party registration for Extension 2, as shown below. Note that the TO header <user-id> parameter is the User-B primary extension.
