I have had success putting something like either of the following in front of all incoming calls. The first sample extension blocks caller ids that are 1-4 digits long or unavailable. The second blocks anything that isn't 1nxxnxxxxxx. You could take the first and add in a couple more terms to catch your blocked caller id calls. <extension name="spamkill"> <condition field="caller_id_number" expression="(^\d{1,4}$)|(^Unavailable$)" break="on-true"> <action application="answer"/> <action application="sleep" data="1000" /> <action application="hangup" data="UNAVAILABLE_CALLER_ID_A" /> <action application="log" data="INFO Another unavailable caller terminated." /> </condition> </extension> <extension name="spamkill_max" continue="true"> <condition field="caller_id_number" expression="^\+?1[2-9]\d{2}[2-9]\d{6}$" > <anti-action application="answer"/> <anti-action application="sleep" data="1000" /> <anti-action application="hangup" data="UNAVAILABLE_MAX" /> <anti-action application="log" data="INFO Another caller killed by terminated." /> </condition> </extension> Nick On Mar 2, 2013, at 1:04 PM, Tamer Higazi <th982a@googlemail.com> wrote:
