You can execute a dialplan subroutine on the caller channel and on each callee channel dialled. There are two ways in which, Channel is ${CHANNEL}) same => n, Dial(SIP/alice, Dial(SIP/bar, Hangup() exten => caller_handler, In caller pre-dial handler!) same => n, NoOp() same => n, Pre dial handler, Pre-dial handlers allow you to execute a dialplan subroutine on a channel before a call is placed but after the application performing a dial action is invoked.
