Scott, I have changed the configuration as said it and will test it. I’m
curious.
Can you briefly explain what insecure=invite,port does?
;insecure=port ; Allow matching of peer by IP address without
; matching port number
;insecure=invite ; Do not require authentication of incoming INVITEs
;insecure=port,invite ; (both)
Do I understand correctly that in this mode the IP address is not checked and
no authentication is required?
