Client stations download spa$PSN.cfg and init_$MA.xml only once for initial configuration.
However, they download generic.xml on every reboot. Therefore, parameters manually
configured on the client station that overlap with the contents of generic.xml are overwritten
with the SPA9000-supplied values. The list of parameters included in generic.xml are thus
purposely kept to a very small set.

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
Via: SIP/2.0/UDP 192.168.0.4:5060;branch=z9hG4bK-8865c41e

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.
