Please please HELP me
You told us nothing that would help us.
You need to slow down.
What version Asterisk/FreePBX/DAHDI and how was it installed (distro or by hand). If by hand need the OS and versions.
What model digium card.
Output of ‘dahdi show channels’
Log for failed call.
to be honest with you sir i am really familiar with this technology,
the version is freepbx 2.7.0.3, i used elastix 2.0 to install this box, and digium TDM2400P.
this is the message show by dahdi show channel

Sorry really…
Elastix uses “patched” versions of Asterisk, Dahdi and FreePBX, and a whole bunch of “helpful” scripts. I really suggest you get help there. Nobody here knows what they do (or why 
)
Not sure what you are sorry for. All your channels are in service so you need to show the ‘dahdi show channels’ when the blocking is occurring. We also need the log as I requested (at the moment of failed call).
Then start going through the channels 1 at a time with ‘dahdi show channel 1’ and so on and see what state the channels are in at the time of the blocking.
