Re: [SR-Users] Dispatcher does not go to 2nd server

I experience something really strange when i change the dispatcher list to have the same priority both of the servers. I am getting 401 (unauthorised) to the extensions trying to register. Even though they in asterisk they seem to be registered, the debug shows 401. Not able to call from one extension to the other. here is the console error: /*<--- Transmitting (NAT) to 192.168.0.99:5060 <http://192.168.0.99:5060> ---> SIP/2.0 401 Unauthorized Via: SIP/2.0/UDP 192.168.0.99;branch=z9hG4bKe78c.2793112e87a37f021cda7a582ba8c703.0;received=192.168.0.99;rport=5060 Via: SIP/2.0/UDP 192.168.0.117:5060;received=192.168.0.117;branch=z9hG4bK823694525;rport=5060 From: <sip:500@192.168.0.99 <mailto:sip%3A500@192.168.0.99>>;tag=580308996 To: <sip:500@192.168.0.99 <mailto:sip%3A500@192.168.0.99>>;tag=as4657cc95 Call-ID: 822746835-5060-1(a)BJC.BGI.B.BBH CSeq: 2005 REGISTER Server: Asterisk PBX 11.25.3 Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="73fd892f", stale=true Content-Length: 0*/ On the other hand if i change the priority to 0 & 1 the servers respectively, then no errors in asterisk console and they can call between each other. This is really odd.

Especially for the modparam settings that Mr Jurijs Ivolga is proposing, I already had them. it is the kamailio.cfg that I originally attached. Unfortunately I did not manage to find anything in the parameters that will solve the problem as proposed by Villasmil and Semenov. I have given a try on changes but nothing good came up.

In your configuration there are couple of things to have in mind: need to set correct flag param https://kamailio.org/docs/modules/5.5.x/modules/dispatcher.html#dispatcher.… select the algorithm used to select the destination (ds_select_dst) and have a faulure_route where the next destination will be tried in case first is down.  You can find the examples in the module doc.

All users are created in both of the asterisk servers. I am forwarding the registration to asterisk. The problem is that it is always used on only one server from the list. Even if one goes to shutdown, then there is not any registration sent to the available server. Even if _*some *_of the extensions can be seen registered in both of the asterisk's, if the secondary goes down, then there are no services for the phones. I am attaching the kamailio.cfg. My dispatch list is: 1 sip:192.168.0.100:5080 <http://192.168.0.100:5080> 0 0 maxload=20 2 sip:192.168.0.101:5080 <http://192.168.0.101:5080> 0 0 maxload=20 In both of the asterisk servers i am using sip.conf to create users and s sip trunk for the Kamailio. Nothing special about it. I am looking to find what is wrong with my config and i cannot loadbalance/failover to the asterisk servers. _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org <mailto:sr-users@lists.kamailio.org> https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users -- Arsen Semenov _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org <mailto:sr-users@lists.kamailio.org> https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org <mailto:sr-users@lists.kamailio.org> https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org <mailto:sr-users@lists.kamailio.org> https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
