[Asterisk-Users] regexp issue

[Joao Pereira]

Hello to all
I had Asterisk dialing the PSTN through a defined trunk.

But when I enabled the SIP URI calls....  Asterisk stopped contacting 
the PSTN trunk....

The SIP URI dial code (who created the problem) is this:

exten => _.,1,NoOp(Incoming Call from from-internal-custom extension 
${CALLERID} for ${EXTEN}@${SIPDOMAIN})
exten => _.,2,GotoIf($[${LEN(${SIPDOMAIN})} = 0]?10)
exten => _.,3,GotoIf($[${SIPDOMAIN} = ${MYDOMAIN}]?10)
exten => _.,4,GotoIf($[${SIPDOMAIN} = ${MYFQDN}]?10)
exten => _.,5,GotoIf($[${SIPDOMAIN} = ${MYFQDN}:5060]?10)
exten => _.,6,NoOp(@${SIPDOMAIN} is remote, forwarding...)
exten => _.,7,Macro(uridial,${EXTEN}@${SIPDOMAIN})
exten => _.,8,HangUp()
exten => _.,10,Goto(custom-noturi,${EXTEN},1)
exten => h,1,HangUp()

How can I say that this code is just for calls to foreign domains?

Something like:    if (SIPDOMAIN != fccn.pt)
