[asterisk-users] Dialplan flow on device state change

[Andrea Spadaccini]

Hello everybody,
is it possible to execute some dialplan code when an extension changes its
state?

Say that SIP/204 becomes busy. I know that using the hint priority some phones
can show its state. Am I able to call custom code in the same way?

Thanks in advance,
