I recently got my Cisco 7965 registered with my other 2 and they work perfect running SIP, I want to setup BLF presence but no luck if needed I can upload my SEPMAC thanks in advance!! And I am not using endpoint manager

BLF does not work on these old Ciscos with standard Asterisk. You have to patch Asterisk. Documentation Overview

Does it work either way the latest asterisk?

The patches have been working great for many years, but it takes a lot of time…if you are a newbie. The current patch for Asterisk 22 is ready for testing :wink: It is not easy to patch Asterisk on a freePBX system without destroying something…

Thankfully I made a recovery point so I can try and fail, I found guides but it keeps using the “yum” and mine is APT so it’s kinda hard.

Sounds promising I’ll have to take a look thanks!! Should I just use Ubuntu? Without a GUI

also does the BLF work on pjsip or just sip

You need to use the chan_sip patch. No one is making this work for chan_pjsip.

for some reason after patching asterisk 20 for sip its not showing in the extension menu or a channel driver in advanced

@kgupta mentioned in this thread that one could install asterisk first, patch it…and install freePBX17 with the –noasterisk option afterwards. I never tried this approach, but it might work.
