[Asterisk-Users] SIP registrations

[John Todd]

Why would you use anything other than what's in the sip.conf file? 
You can now configure (though I have not tried it myself) usernames 
with "@" symbols in them.   I am having a lot of difficulty parsing 
your question.  Just give people usernames of 
"username at domain-name.com" then and map them to some meta-extension, 
and set it up that way in sip.conf, like this:

[1234]
type=friend
username=jtodd at somewhere.com
secret=jtoddspassword
host=dynamic

This is for registering to remote servers for calls inbound to Asterisk.

To explain: I have an account on my company's SIP proxy/gateway 
system at work.  They gave me a username of "jtodd at bigcompany.com" 
and password of "deadrabbit".  I want to use Asterisk to route my 
calls from Bigcompany's SIP server into one of my SIP phones.   I 
have created an extension in context "from-sip" called 2203 which 
takes inbound calls and routes them to my SIP phone.

So, in sip.conf I put the following config in the [general] context:

[general]
port = 5060                     ; Port to bind to
bindaddr = 0.0.0.0              ; Address to bind to
context = from-sip              ; Default for incoming calls
register=jtodd at bigcompany.com:deadrabbit at sipserver.bigcompany.com/2203


; here is the definition for my ATA-186 SIP phone
; (note: this config is abbreviated; does not include outbound config 
for ATA-186)
[2203]
type=friend
username=2203
secret=passwordforata186
host=dynamic
canreinvite=no


Now, in extensions.conf I put something like this:

[from-sip]
exten => 2203,1,Dial(SIP/2203)


That's it!  When I fire up Asterisk, it sends a REGISTER to 
sipserver.bigcompany.com and notifies that server that my Asterisk 
server is accepting calls for my account.  Then, when calls come in 
from that account.  Then, when calls come in from that account, 
Asterisk points them at extension 2203, which in turn dials my 
ATA-186.
