[SR-Users] Kamailio and Nonce Count

[patrice.bodeven at orange.com]

Hello,

I try to understand the nonce count handling.

By parameter "modparam("auth", "nonce_expire", 21600)" I can define the validity of the Nonce in the time.

But I want also to define the validity of the Nonce in the number of use. For exemple, I want to limit the reuse of the nonce at 64 times (including register, Invite)
But I can see the definition of the nonce_count for all the SIP users on Kamailio and not user per user.

If I understand when I use
modparam("auth", "nonce_count", 1) # enable nonce_count support
modparam("auth", "nc_array_order", 20)   #  1M in-flight nonces, using 1Mb memory
modparam("auth", "nid_pool_no", 4)
I define a memory to store the nonce values for all the SIP users.
So when User A use nonce x for REGISTER and nonce y for INVITE, nonce x is still valid !

My understanding is it correct ?

Is anyway to define a nonce validity in number of times per user ?
