[asterisk-users] Error Dialplan ?

[Phibee Network Operation Center]

Hi

I have a problems with a new Asterisk Server,

when i want call, i have:

    [Nov 14 09:12:38] NOTICE[31992]: chan_sip.c:18160 
handle_request_invite: Call from 'PHISIP000001' to extension 
'00420225352184' rejected because extension not found.

but into my extensions.conf:

        exten => _00420X.,1,Set(CDR(CodeTier)=CZE)
        exten => _00420X.,2,Dial(SIP/${EXTEN}@AS5350,180,rt)
        exten => _00420X.,3,Hangup

and a dialplan show:

        exten => _00420X.,1,Set(CDR(CodeTier)=CZE)
        exten => _00420X.,2,Dial(SIP/${EXTEN}@AS5300,180,rt)
        exten => _00420X.,3,Hangup


I have a error, it's sure because i am new user, but ?


context of the user are good

thanks
