Very strange problem with Messagenet Provider:
after boot the PBX work fine, but after some hours i get this message:

05-23 18:10:49: Register failed (Authentication error) - sip:53*****@sip.messagenet.it:5061

re-register don't help
enable / disable ARS don't help

the only way is to "Restart ALL"

do u have any idea?

let me know
thanks

will the same thing happen when use latest version of pbx?

you can try set shorter "Register Update Period (%)" in ARS rule like 50 and check if the same thing happen

if capture packets, is there re-register request sent from brekeke to provider when previous register is almost expired?
and what response sent from provider?
