in a dialplan extension, i have <action application="set" data="call_timeout=30" /> then <action application="lua" data="bridge.lua ${effective_caller_id_number} $1"> in which call bridging is to be processed, after this, is <action application="bridge" data="loopback/app=voicemail:default ${domain_name} ${dialed_extension}" /> to transfer the call to voicemail. the purpose is to test no-answer till timeout and see if the call is transferred as planned. but nothing happened untill 60 secs after the dial, which is the default value of call_timeout. in my understanding, when lua takes over, the channel variable call_timeout is no longer effective and will not affect what happens in lua script, so i tried session:execute("set", "call_timeout=30"); in bridge.lua, but the problem is still there. how to make call_timeout work with lua, could anyone figure this out?
