Private Name commented on ASTERISK-22580:
-----------------------------------------

I no longer have access to a box with this version. I was scolded for putting Asterisk 12 in production, and decided to follow the advice given. Also, the channel PJSIP is useless until it updates the channel variables, like the regular SIP channel does, i.e., CHANNEL(recvip), etc. It does not. By the way, the CHANNEL() needs a variable with the inbound peer name, if any, and a flag that says if it is registered or not, since a peer does not need to register.
