Bridge ID Variable?

Asterisk Asterisk Dialplan

Hi folks,
Is it possible to get BridgeID just like a ${CHANNEL} variable?

I don’t believe we expose that in the dialplan. For what reason do you want it?

Actually i initiate a call which later on bridged to another party so i do not have a record of channels for my call. i need all channels for my call.
