[asterisk-users] Help: How to configure SIP domain on SPA942

[Philip Prindeville]

I'm using a bunch of SPA942's, and I'm trying to provision them mostly 
by DHCP (and what I can't set that way, I try to provision via HTTP 
interface into the phone).

I changed the domain in my AstLinux config from "astlinux" to redfish-solutions.com, and set
that in my sip.conf file as well:


context=incoming                                                         
canreinvite=no                                                           
realm=redfish-solutions.com                                              
domain=redfish-solutions.com,incoming-redfish                            
tos=184                                                                         
disallow=all                                                                    
allow=ulaw                                                                      
allow=gsm                                                                       
localnet=192.168.10.0/255.255.255.0                                             
externip=X.X.X.X


(Footnote:  do I need a default context?  I'd rather not having one... I'd rather specify where
my calls go explicitly...)


However, my phones don't seem to be registering with any (symbolic) domain...  just the IP address
of their DHCP or TFTP server (can't tell which, since it's the same box).

The config seems to take:

Our local SIP domains:                   Context              Set by          
redfish-solutions.com                    incoming-redfish     [Configured]    


So, what's the DHCP option (or the HTTP knob) to tweak to get the phones to
think they are in the redfish-solutions.com domain?

Thanks,
