[Freeswitch-users] how to prevent of changing the value of nonce ttl sip auth ?

[Stefan Shortner]

HI,

i find out every time we want to register on sipclient 
the sip_nonce_auth  get the value,and every time we unregister the same 
sipclient the value of sip_nonce_auth
was changed !
but is there any solutions to prevent of changing 
the value of sip_nonce_auth for same sipclient that registered and 
unregistered?
because suppose we have 25 sip client that is registered 
on our server,now i want to check the sip client that is registered be the same 
that is unregistered
so if the value of sip_nonce_auth for the sipcliet be 
the equal with the value of the same sipclient that is unregister ,the problem 
will solve,

in the internal.xml we have <param name="nonce-ttl" 
value="60"/> 

it means every 60sec the value of  sip_nonce_auth for 
each sipclient was chnaged ,
and if the value of  nonce-ttl is less than the value 
of  parametere "register every ... " softphone, so the nonce-ttl was changed 
again.

but i don't want change to check every sip client that 
is registered is the same that is unregistered
i want when the status of sipclient was changed to 
'unregistered' form 'registered' the value of 'sip_nonce_auth' be the same  to 
find out the sip client that
is registered was the same that is unregistered !

is there any solutions?

( i know we can check using fs_cli with sofia status 
profile internal reg and sofia_count_reg ..) but i want to check with sip header 
...

for example when sipclient is registered

as you see the sip_auth_method is the same when user is 
registered AND unregistered ...
but how can i findout  that ? 

is there any method to change the 'sip_auth_method ' to 
another value when sipclient status was changed to 'unregistered'?
thanks in advanced
