uuid_kill is an API command, not a dialplan application. It might be cleaner for you to use the execute_extension dialplan app to execute a simple dialplan extension that uses the set app to execute the API per this wiki entry: https://confluence.freeswit.ch/display/FREESWITCH/API+Commands (see "from the dialplan" section) Another advantage to using the execute_extension app in your bind_meta_app call is that you can have other things occur like spitting out log info. <action application="bind_meta_app" data="# a b execute_extension::${uuid_of_b_leg} XML foo"/> <context name="foo"> <extension name="hangup b leg"> <condition field="destination_number" expression="^(.*)$"> <action application="log" data="INFO Hanging up B leg uuid of $1"/> <action application="set" data="res=${uuid_kill($1)}"/> </condition> </extension> </context> Please note that the standard disclaimer <https://wiki.freeswitch.org/wiki/Reporting_Bugs#Standard_Disclaimer> applies to the information I've presented here. -MC
