[asterisk-users] Unicall - How to automatically block collect calls

[Oscar Patricio]

Hi!

I am using asterisk with unicall in brasil.

Everything was working fine, but now we want to set up a way to 
automatically drop collect calls, because we have an IVR answering all 
calls automatically!

Can you tell me, what I have to configure to block collect calls in the 
asterisk?

Thank you!
Best regards,

Óscar Patrício
