Asterisk 12.8.0-rc2 + FreePBX + PJSIP based SIP.
The task is to call System on a certain number, where as one of the parameters to transfer the IP address of the calling extension, I can’t figure out which variable to transfer to it.

Answer 1

This is stored inside the ${CHANNEL(uri)} variable, you may need to cut ip out of it with a regular expression.
