Hello! I'm trying to make such scheme: ---> FS_A --> FS_B --> record Incoming calls to FS_A are redirected to FS_B with the help of this context: <extension name="redirect"> <condition field="destination_number" expression="^(2000\d)$" > <action application="answer" /> <action application="set" data="continue_on_true=false" /> <action application="bridge" data="sofia/outbound/$1@1.2.3.4:5080" /> <action application="hangup" /> </condition> </extension> FS_B records them to the file: <extension name="30xxx-wr-wav"> <condition field="destination_number" expression="^20001"> <action application="answer" /> <action application="set" data="hangup_after_bridge=true" /> <action application="record" data="$${base_dir}/recordings/test/testrec.wav" /> </condition> </extension> This works good. But I have a question - in what manner I can send back (from FS_B to FS_A) some channel variables? Thanks, Evgeniy.
