Subject: Re: [asterisk-users] fallback to default extension

Hi

I've pretty much have it setup properly with the following:
exten => _24XX,1,Dial(SIP/${EXTEN},30)
exten => _24XX,n,GotoIf($${DIALSTATUS}"="CHANUNAVAIL?noconn:conn)
exten => _24XX,n(noconn),GotoIf($["${EXTEN}"="2400"?conn:force)
exten => _24XX,n(force),Dial(SIP/2400)
exten => _24XX,n(conn),hangup()

The only problem is that if 2400 rejects the call asterisk tries to
call extension 2400 again...
What am I doing wrong and how do I fix it?

TIA
Paolo
