You need to check the SIPDOMAIN early in the outgoing sip context for the
callee. I don't know your context here.
Also, please make sure you have an new CVS checkout, I don't know which version
you're running. Run 'grep SIPDOMAIN' in chan_sip.c to make sure it's there.

Here's what I do early in thte outgoing SIP context for clients:

;------------------------OUTGOING CALLS FROM SIP-------------------------
[sip-callers]

;----Match everything
exten =>_.,1,SetGlobalVar(sipto=${EXTEN})
exten =>_.,2,SetGlobalVar(sipdom=${SIPDOMAIN})
;Every extension will go here, including h, t, s
;Filter out hangups
exten =>_.,3,gotoif,$[${sipto} = h]?30|1:5|1

;---Test if external dial - on domain name
exten =>5,1,gotoif($[${SIPDOMAIN} = ${MYCURRENTDOMAIN}]?20,1:10,1)
;--------------------------------------------------------------------------

MYCURRENTDOMAIN is set early in extensions.conf to the servers SIP realm.
