<div>Hi Carlos,</div>
<div> </div>
<div>The method commonly used is "flash" E1 to block this calls. </div>
<div>A Better way could be detect the category of call.</div>
<div>I donīt know if there is a way to get the call category in extensions as we can get the CALLERID. </div>
<div> </div>
<div>Collect calls have B-8 category in Brazil.</div>
<div> </div>
<div>Thanks. </div>

<br>it in case someone has a solution for this.<br>I'd like to know if there's some way to "detect" (not block) a collect<br>call in a ISDN E1? I need this cause I have my own billing system and<br>I need to charge my customers for collect calls they receive.
<br>Currently I have to get the PSTN billing and locate all collect calls<br>and then enter it manually. I want to detect these calls in asterisk<br>so I can automatically charge my customers.<br><br>For Brazilians in the list, I have a Embratel E1 - ISDN.
