[asterisk-users] getting real sip status after dial

[Khalil Khamlichi]

This does not work either.
getting returned sip code out of asterisk turns out to be very time
consuming, even though it is something that is already available to
PJSIP, I can see the information in sip logger, and asterisk forwards
the sip status code to the soft-phone. but does not give access it on
the dial-plan.
