[OpenSIPS-Users] Why is OpenSipS sending a 407

Bogdan,
I had a look at:
http://www.opensips.org/html/docs/modules/1.9.x/auth.html#id250176
and I read what it said. Does this mean that anyone that knows my nonce can
make a call and get through to my OpenSipS or is it only an issue if we have
multiple boxes?
Regards,
Dovid

Hi Dovid,
Because by default, the nonce re-usage is turn on in auth module - which
means a nonce can be used for only a single auth processing! and in your
case, same nonce is used in 2 auth cases.
What you can do:
1) make processing in script stateful, so that the second SUBSCRIBE will
be seen as a retransmission and will not hit the auth - use t_newtran()
before the auth part.
2) disable the check for nonce reusage - see
http://www.opensips.org/html/docs/modules/1.9.x/auth.html#id250176
