DAHDI no dial out

Hello Asterisk friends,

Two weeks ago I’ve make my first PBX with Asterisk (1.4.26.2) and FreePBX. Incoming and outgoing calls with the SIP protocol works perfect and incoming calls with the DAHDI protocal works perfect too. Only outgoing calls with the DAHDI (2.2.0.2) protocol does not work, you heard only tuut, tuut, tuut when you call somebody.

With “Asterisk -r” get I the follow error:

-- Starting simple switch on 'DAHDI/3-1' -- Hungup 'DAHDI/3-1'

Ofcourse I’ve search on Google but no results… Below you can found my DAHDI config and I’ve activated the DAHDI compatibility mode.

/etc/dahdi/system.conf

loadzone = us defaultzone=us fxoks=1,2,3,4

Thanks for helping me!

Regards,
NeverMindS

P.S. Sorry for my poor English
