[asterisk-users] dial, answered and then hangup

[Rilawich Ango]

Hi all,

  I will a TDM card with FXO modules on it.  Below is the dial plan.
When someone can 9123456, CLI will show dialing to 123456 and
answered.  After answered, the call hangup.  I would like to know what
will cause the case to happen.  Anyone can give me some advice to
solve it?

exten => _9X.,n,Dial(Zap/g0/${EXTEN:1}|${RINGTIMEOUT})
exten => _9X.,n,Hangup
