[asterisk-users] All trunk are busy please try your call again later

[Lolu Gbenga]

Good Day all

Please I am having some issues on my voip asterisk server

I make internal calls on extensions configured ie extension 192 can
call extension 195 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.

Best Regards

Success
