string Command or api to be executed on the B leg before bridging the two channels. Useful when originating a call from the event socket, CLI or XML-RPC.

It could for instance be used to do a HTTP GET with a script or mod_http to the IP address of a Snom phone to increase the ringer volume if you need to do a wakeup call.

Can also be used to bind a dtmf to an app on the b leg of a call so that it can survive a transfer.

Arguments can be passed to the app with bridge_pre_execute_bleg_data.

(warning) this is executed AFTER the call is setup but BEFORE the media (audio) is bridged.
