Registers before any calls are made.

Probably your extension name and registration data don't match.  Here is 
my SIP config and a list of the GS phone settings:

[exten106]
type=friend
context=administrator
callerid=<829-3289 106>
username=sbesch
host=dynamic
dtmfmode=info		;or inband if you prefer
secret=yourpassword
qualify=5000
mailbox=106
canreinvite=no		;As long as the phones are NAT'ed

The caller ID only means something to our internal extensions, since the 
phone company will not let me set callerid data. I don't think that the 
username is needed. I use it because it shows up in the CLI response to 
SIP SHOW PEERS and helps me identify the phone. The important bits are 
that the extension name (the part in "[]") and the secret match the data 
in the phone setup:

Sip User ID: exten106
Authenticate ID: exten106
Aithentication Password: yourpassword
Sip Registration: Yes
Send DTMF: via SIP Info


Don't make the mistake of thinking that the username entry in SIP.conf 
has anything to do with the Authenticate ID. IT doesn't. The only thing 
that works is to set the User ID and the Authenticate ID to the same thing.

You may find that the GS phones will dissappear after a while if you use 
dynamic registration. Alas, this is a bug in the GS firmware(1.0.3.81). 
I don't know if it has been fixed in later releases. I am not willing to 
update my phones until the firmware gets much more stable - they are all 
working and my philosophy is that if it ain't broke, don't fix it - so I 
haven't been able to test this. If your phones have fixed addresses, you 
might as well specify the IP addresses in SIP.conf and preemptively 
avoid the problem of the GS registrations dissappearing.
