Kamailio 5.0.8 | authentification issue only with TCP/TLS
by Laurent Schweizer 29 Aug '19

29 Aug '19

Dear all, I have a kamailio running in version 5.0.8 and since fee weeks we have an issue with different users connected in TCP or TLS, sometimes authorization like for REGISTER are rejected and after a moment (can be few minute or hours) it work again and of course no change was done in the password .... We see this issue with different device, snom swyx, ... and on UDP we have no issue. I can see that when the Register is rejected it's with the error -2, so wrong password... # Authentication route route[AUTH] { if (is_method("REGISTER")) { # authenticate requests if (!auth_check("$fd", "subscriber", "1")) { switch($retcode) { case -1: sl_send_reply("503","Service not available"); exit; case -2: xlog("L_WARN", "auth error -2 username $au - src ip: $si \n"); auth_challenge("$fd", "0"); exit; I have attached an example of a trace where we can see a first REGISTER accepted and less than 2 minutes after a new one is rejected. ( in between they is a REGISTER without any Authorization header) Any idea ? BR Laurent

Connect Kamailio to ITSPs?
by Aingaran Thirunadarajah 29 Aug '19

29 Aug '19

Hello, Newbie here! Have Kamailio set up on a 512MB VPS. Created a couple of users, registered with Zoiper and can call between them. I am looking for documentation to connect the server to other VoIP providers (Signalwire, Anveo, VOIP.ms etc.) to make & receive calls from the external network (DIDs) / PSTN Can someone point me in the right direction? Thanks in advance.

Define properly IP in record-route header
by przeqpiciel 29 Aug '19

29 Aug '19

Hi, I have some issue and dont have enought knowledge to fix it. I have simple infrastructure. Internet -> router (NAT) -> kamailio -> asterisk Kamailio and Asterisk are inside the network and Kamailio places his own private address in the "record-route" headers instead of who's public. There is configuration to said to him what IP is proper ?

Disable GW's on runtime
by Duarte Rocha 28 Aug '19

28 Aug '19

Greetings, I have two Kamailio's working on a HA scenario. Both Kamailio's have DB replication and each machine has one HA IP. In order to set this up, i have every GW on the DB duplicated, one with Socket IPA and another with socket IPB. I have both GWs in a active state configurated in the replicated DB. They also both have the same URI and the same group id Example : GW1 : Socket = IPA ; GroupID = 1 ; Uri = sip:1.1.1.1:5060 GW2 : Socket = IPB ; GroupID = 1 ; Uri = sip:1.1.1.1:5060 In order to avoid errors, i want to disable on runtime the GWs that have a socket that doesn't belong, at the moment, to that machine (GW with Socket IPB on machine with IPA). To do that i would use the dispatcher.set_state, however it works with group id and address, which in this case it is the same. Is there other method to disable the GWs on runtime using other arguments like duid or socket ? I thought about using probing for this, since it will disable automatically the GWs with non-existent socket, but not all my clients support probing, so it isn't feasible. Thanks in advance

UAC ha1 password
by Alexandru Covalschi 28 Aug '19

28 Aug '19

Hello, I'm trying to make Kamailio to SIP register on a remote server. However storing plaintext password looks very unsecure. Is there a possibility to store password for uac module using ha1 hash instead of the plaintext password? I see there's a row for it in the database, but in the source code it's not used and it seems i can't neither use it in db neither set up in-memory as avp. Maybe there's a workaround to directly access the in-memory uac registration htable? ________________________________ Regards, Alexandru Covalschi VoIP Engineer and System Administrator tel: +37367367850

controlling presence with new module `pua_json`
by bill＠novatrope.us 28 Aug '19

28 Aug '19

Hi all: I am trying to use the procedure for setting BLF lights described in https://blog.voipxswitch.com/2018/02/22/kamailio-controlling-presence-with-… WIthout success. My configuration is 1 Grandstream GXP2130 phone behind a NAT on a public IP. (IPP in example below) Kamailio is running on public IP (IPK in example) listening on port 50060 The command I am sending: curl -d '{"Call-ID":"1020101@<IPP>","Event-Category":"presence","Event-Name":"update","Event-Package":"dialog","Expires":"3600","To":"sip:1020108@<IPK>:50060","To-User":"1020108","To-Realm":"<IPK>:50060","From":"sip:1020101@<IPP>","From-User":"1020101","From-Realm":"<IPP>","State":"Confirmed"}' http://localhost:8080/presence/ {"Call-ID":"1020101@<IPP>","Event-Category":"presence","Event-Name":"update","Event-Package":"dialog","Expires":"3600","To":"sip:1020108@<IPK>:50060","To-User":"1020108","To-Realm":"<IPK>:50060","From":"sip:1020101@<IPP>","From-User":"1020101","From-Realm":"<IPP>","State":"Confirmed"} Kamailio appears to be processing the command OK, so I think I am just not setting it up properly> Anybody having any luck with this procedure, let me know how you are getting it to work.

[tm-local-request] usage
by Duarte Rocha 28 Aug '19

28 Aug '19

Greetings, Does "event_route[tm:local-request]" works like onsend route ? I'm having some problems and i'm using local-request to debug and i found this on the documentation : "Executed after the tm module has sent a local generated, transaction stateful request." I'm logging all the requests that go through this route. Is this really the last place before kamailio send the request? If the request is logged here, is there anything more in kamailio that can stop the request (pipelimit, etc) ? If a packet gets logged on this route does that mean that it was already sent? Best Regards, Duarte Rocha
