if you doing
EXEC GOTO 99 in an AGI
you agree it should go at priority 99 right?


and here's my CLI's output:
    -- AGI Script Executing Application: (GOTO) Options: (99)
    -- Goto (test_sip,1001,99)
    -- AGI Script Executing Application: (SetLanguage) Options: (fr)
  == Spawn extension (test_sip, 1001, 98) exited non-zero on 'SIP/154-4cea'



asterisk*CLI> show dialplan 1001@test_sip
[ Context 'test_sip' created by 'pbx_config' ]
  '1001' =>         1. AGI(papers/papers.agi|1001)                [pbx_config]
