asterisk users - Mar 2008 - Calling users to the external domain using Asterisk

Hi All,
 
I am a newbie to Asterisk. Presently I am working with Asterisk 1.4.17
and using it to make SIP calls.
I have a configuration of Asterisk which serves the users in a
particular domain, say internal.com
I would like to make a SIP call from bob at internal.com to
charles at external.com 
I have added the following lines in extensions.conf
exten =>  charles,1,Dial(SIP/${EXTEN}@external.com)
exten =>  charles,2,Hangup
 
Asterisk does a DNS SRV lookup and resolves the external.com to its
proper IP and calls are established.
But the problem with the above configuration is that I have manually
added users that are in the external domain.
 
Is there any way wherein I can call the users in external.com without
adding them in the extensions.conf?
 
Any help would be appreciated.
 
Thanks,
Aadil

I could be wrong about this, but isn't that what a switch statement is 
for? So you might check to see if the dialed number is local to 
internal.com, then you might do a switch statement to external.com's 
dialplan if it wasn't local?

What you are looking for is something like this piece of code. Adapt it for
your scenario:

[default]
exten => _.,1,NoOp(incomming call from ${CALLERID} to ${EXTEN}@${SIPDOMAIN})
exten => _.,2,GotoIf($[${LEN(${SIPDOMAIN})} = 0]?10)
exten => _.,3,GotoIf($[${SIPDOMAIN} = ${MYDOMAIN}]?10)
exten => _.,4,GotoIf($[${SIPDOMAIN} = ${MYFQDN}]?10)
exten => _.,5,GotoIf($[${SIPDOMAIN} = ${MYFQDN}:5060]?10)
exten => _.,6,GotoIf($[${SIPDOMAIN} = 192.168.1.1]?10)
exten => _.,7,NoOp(@${SIPDOMAIN} is from an external domain, sending to
it...)
exten => _.,8,Dial(SIP/${EXTEN}@${SIPDOMAIN})
exten => _.,9,HangUp()
exten => _.,10,Goto(noturi-default,${EXTEN},1)
exten => h,1,HangUp()

[noturi-default]
;(your dialplan)

Ricardo Carvalho.
