Refresh time of provider status

Hi, i have two problems with registration statuses(sip show registry)

1)Status registered don’t change long time even line to provider is down

2)when line is going up status is “No Authentication” and no request is sent to register

Thank you for help

qualifyfreq

and the three lines before it in the sample configuration.

Note the remote end may limit registration frequency.

Also, it would be strange for a provider to register with you.
