I think I have fixed the authentication issue yet the SIP dialog has completely changed. Now the dialog involves Asterisk sending SIP NOTIFY to Kamailio, which is then forwarded to the client. Kamailio.cfg has no routes to handle NOTIFY and there are no SUBSCRIBE messages preceding the NOTIFY. Only REGISTER and 200 OK. Is this expected behavior? The sipregs database is now correctly updated when a peer registers so that's good.

Thank you for the qualify solution, that worked.

However, on the KB by asipto, they only create a `sipreg` and `sipusers` table and then in extconfig.conf for asterisk, sipusers and sippeers are both using the `sipusers` table in MySQL. 

I included a sip trace in the original email but I will include a more detailed sip debug here. It looks like Asterisk and Kamailio can exchange messages but for some reason, the SIP dialog stops after Asterisk sends back a SIP 401 Unauthorized to Kamailio. Any ideas?

Maybe you got to get some traces with sip set debug on on asterisk or ngrep in kamailio to check whereis the problem.

I think you are not authenticating correctly

Check if you insert on sipusers and sipppers table what is commented on KB by asipto.

Maybe your Kamailio is not responding to OPTIONS (qualify=yes)

add at the beginning of your kamailio.cfg file
request_route {

    if(is_method("OPTIONS") ) {

                sl_send_reply("200","Keepalive");

                exit;   

        }

Thanks for your response.

I did read the section about the secret in the kb url. I followed the example and inserted the test users on tFe url (101, 102, 103) and they have secret set to NULL. I have tried both secret=NULL and secret="" and Asterisk still asks for authentication. Also when I do "sip show peers" I get:

Name/username             Host                                    Dyn Forcerport ACL Port     Status      Description                      Realtime
kamailio-inbound          kamailioIP                               a             5060     Unmonitored

I added qualify=yes and now:

Name/username             Host                                    Dyn Forcerport ACL Port     Status      Description                      Realtime
kamailio-inbound         kamailioIP                               a             5060     UNREACHABLE

Could this be the issue? I have verified that Kamailio receives the responses by doing ngrep and I can see the SIP 401 from Asterisk.

Maybe I am missing something else? I'm not sure I understand how Asterisk's peer selection affects this. When I received the registration request from Kamailio, the From: address and domain are the same as the To: address and domain, which are the values I have set in the sipusers table. 

Another thing, even though the client handset says registered, the table 'sipregs' is not updated with fullcontact, regseconds, or any data at all. Yet I can still make a call. So maybe Asterisk is not authenticating INVITES (whether or not it's registered) and that's why I can call.

Any further help or things I should try?

You could remove secret= on extensiones to check if its related to authentication or not

You must not request authentication to kamailio in order to work properly in front of Asterisk

As Daniel mention check if Kamailio peer is created and extensiones have no secret.. you would need to add alternate sippasswd table for kamailio authentication

Hi, I've been following this integration tutorial http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb and have a successful registration and I can even make calls through my asterisk box.

However what is unusual to me is that every time a phone registers with Kamailio, that is forwarded to Asterisk (as expected), yet Asterisk replies with 401 Unauthorized. Oddly enough the phone registers and can still make calls. What worries me is that as we scale to 100's of cps, this seemingly erroneous message may slow down Asterisk because it's trying to handle authentication for users which have already been authenticated by Kamailio. If this behavior is expected, then that would be good to know as well.

This is the sip debug from ASTERISK (I have replaced IP's with the names of the servers):
