Hey guys, thanks for all the replies and suggestions. I just compared /etc/asterisk/asterisk.conf between the two FreePBX boxes and they are both identical.
After thinking about that code, I am not so sure that is the snippet where it decides to print SIP registrations to the log file. Because I get them all the time on “Box 1” where the IP address does not change. Any other ideas possibly? I would be most appreciative to get this fixed. I was thinking of asking ChatGPT in a little while to see just how smart it is or not, haha
It looks like I may have got a forked chan_sip. The problem with chan_sip is that is no longer present in the master branch of the Asterisk source code, so Google can’t be relied on to return the right project from github. I’ll track down the end of life version.
