Client Registration

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.
REGISTER sip:192.168.0.1:6060 SIP/2.0

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.
