[asterisk-users] Blocking collect calls in Brazil

[Luis Antonio Prata Barbosa]

Hi Carlos,

The method commonly used is "flash" E1 to block this calls.
A Better way could be detect the category of call.
I don´t know if there is a way to get the call category in extensions as we
can get the CALLERID.

Collect calls have B-8 category in Brazil.

Thanks.
