8841 3PCC SIP Reregistering nextnonce

Hi, what am I doing wrong or what am I misunderstanding?

Why is my phone not honoring the nextnonce key?

 

If you look to the log (partial) below, you can see, that the SIP server comes back with a nextnonce value in the Authentication-Info line.

But the phone is still reregistering with the old key and going on for like 8 times until it gets back a 401 (Unauthorized) incl. a new nonce key which it uses then....

I would suggest you raise a case with TAC. I don't think there is a config which controls this.

No contract > no TAC, thats the problem here.

But what could be the reason Cisco did not implement this feature?

 

IETF says: If nextnonce is present, it must be used...

https://tools.ietf.org/html/rfc4590#section-3.5

nextnonce probably is not being used. I would suggest raising a case with TAC to get this looked into.

From the RFC 2617:

3.2.3 The Authentication-Info Header
   The value of the nextnonce directive is the nonce the server wishes
   the client to use for a future authentication response.  The server
   may send the Authentication-Info header with a nextnonce field as a
   means of implementing one-time or otherwise changing  nonces. If the
   nextnonce field is present the client SHOULD use it when constructing
   the Authorization header for its next request. Failure of the client
   to do so may result in a request to re-authenticate from the server
   with the "stale=TRUE".

 

So it's not mandatory to use it according to the RFC.  

Does it mean, that there is no intention from Cisco to fix it?

You will have to contact TAC to get this added to the list of features which need to be added. Once they get a request in it should get scheduled for an upcoming release.

Thanks.

Sorry, no service-contract at our side. > No TAC.

I need to find somebody with a contract to bring the issue up for me.
