I am having issues on my freepbx asterisk box Version 2.0.1
I make internal calls on extensions configured ie extension 367 can
call extension 368 etc
But each time i try to make calls outside the extension ie calling a
GSM or an external line ,i always hear this response “all trunk calls
are busy please try your call again later”
Please how can i resolve this problem .
I will appreciate your response.
