Weird issue, only with registers. Sometimes when I

same issue with both)
my test phone (behind nat) will not register allways getting 401

and it will register (without resetting ser or the phone).
Is this a built in feature or a bug (it only happens when I reset
ser/openser after 60 seconds the
server and phone behave normally).
SER generates a random string to "seed" nonce value in digest
challenge. The random string is generated each time you restart SER.
That means if a user agent sends credentials generated by SER before
restart they will be not valid for restarted SER because the random
string will be different.
You can use secret parameter of auth module to change this behavior.
If you specify the random string manually then random generator will
not be used and digest credentials will be valid after restarts.
The messages below are not related to the problem, because REGISTER
message does not contain digest credentials.

Got me stumped as the configs on the phone and ser don't change.
