<div>We have a need to implement Toll Free call blocking in our Brazil gateways, and can’t seem to find a configuration that works. We have a 2811 running IOS version 12.4.13b, with the following configuration on the E1 controller:</div>
<div> </div>
<div>#sh run | beg controller</div>
<div>controller E1 0/0/0</div>
<div> framing NO-CRC4</div>
<div> ds0-group 0 timeslots 1-15,17-31 type r2-digital r2-compelled ani</div>
<div> cas-custom 0</div>
<div> country brazil</div>
<div> double-answer</div>
<div> category 2</div>
<div> answer-signal group-b 1</div>
<div> description E1 TELEFONICA</div>
<div>!</div>
<div> </div>
<div>With this configuration, collect calls don’t get blocked – they are completed end-to-end. Has anyone ever successfully configured the Cisco router to block collect calls in Brazil? Any help with this would be greatly appreciated.</div>
<div> </div>
<div>Thanks,</div>
