[Freeswitch-users] accessing channel variables of outbound call leg

In dialplan, how can I access the channel variables of an outbound call leg? e.g. <extension name="Local_Extension"> <condition field="destination_number" expression="^(10[0-9][0-9])$"> <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="continue_on_fail=false"/> <action application="log" data="INFO: read_codec=${read_codec}"/> <action application="bridge" data="user/$1@${domain}"/> </condition> </extension> In the example above, read_codec of call leg A will be logged Now I want to print the read_codec/write_codec of outbound call leg in this dialplan. How can I achieve it? -- regards, akhil
