If you need to use the SIP Notify to restart or reset your cisco phones as stated in https://usecallmanager.nz/sip-notify-conf.html , you can do that in FreePBX:
1/ From the FreePBX GUI, go to Admin -> Config Edit
2/ Under the file list section, under "Asterisk Custom Configuration Files", search the file "sip_notify_custom.conf".
3/ Click on that file name and on the right side, copy the content as shown in https://usecallmanager.nz/sip-notify-conf.html .
Like this:
Remember to click Save and Apply after you doing this.
Now, you can issue the command "sip notify cisco-restart xxx"; "sip notify cisco-reset xxx"; "sip notify cisco-prt-report xxx" in Asterisk CLI where xxx is your extension number.
