Asterisk does not accept registration

Hello everyone!

There was a problem asterisk does not return " OK " after user authorization, and of course the phone does not receive this message and tries to register for it and so on.

If you change the IP address on the phone, the problem disappears for a while

Asterisk CLI log:

chan_sip.c:17476 check_auth: Correct auth, but based on stale nonce received from ‘Velikiy sip:300@jabber.comnet.uz;tag=2108556060’

The registrant should immediately respond with the updated nonce from the 401, not wait a second and then respond with the stale one, again. Maybe the 401’s are not reaching it, and it is retransmitting because of an apparent missed response.
