[Freeswitch-users] How to propagate destination number from A-leg to the (B-)leg created by mod_fifo ?

I’m looking for a way to propagate the A-leg called number to the B-leg setup by mod_fifo to the member. (on-hook agents via loopback ) Legs involved: A-leg -> loopback-A > loopback-B —> B-leg I’d like to control the caller_id for the B-leg. Sometimes showing the A-leg caller number (A-number) and sometimes the A-leg called number (the B number) Any wizards out there with a quick answer ? Thorleif
