hello dears, i'm using kamailio 5.1 as IMS , and i have the following servers: * p-cscf * i-cscf-1 ,icscf-2 * s-cscf-1,scscf-2 i need to do high availability and load balancing between my servers , but i have some questions like do i have to use keepalived or dispatcher module and what the benefits of each one of them ,and on load balancing method should i do it for the register requests or only for invite requests or just for every thing ?? if any one has an idea or any thing to guide me i will be thankful thanks in advance and regards

Client Registration and Call over Kamailio
by serkan celik 09 Nov '18

09 Nov '18

Hi all, I am using Kamailio as a proxy in front of a 3rd part Open IMS (Not IMS modules in kamailio). I have defined Kamailio as an outbound proxy in Soft clients(I have configured IMS users info in Soft Clients). When I send register from client to IMS, Register message is sent to IMS over Kamailio. Kamailio forwards this received Register to the 3rd party IMS. Finally the client is registered into IMS over Kamailio. However when I try to make a call from registered users (both registered over Kamailio), IMS sends 403 Forbidden - "Not Registered! You must register first with a S-CSCF" to Kamailio. When I debugged the issue I found the reason why IMS sends 403. When IMS receives an Invite message from Kamailio it checks whether source IP which Invite is sent registered or not. As I make registration over Kamailio without changing contact header, IMS registers the user with the contact IP (which is the client IP). So to make a call from Soft client (IMS users) over Kamailio I also need to register Kamailio source IP as well.To deal with the issue I have changed the contact address of Register message coming from Soft client with Kamailio IP on Kamailio. Then IMS registered Kamailio IP as a contact when registering IMS user. But this time when I make a call from Soft client over Kamailio, IMS sends Termination Invite to Kamailio. So to finalize the call Kamailio has to route this termination Invite to the terminating IMS user . Is there any better approach to overcome this issue. Which is the better approach to use Kamailio in front of IMS. I want to both register and make a call from Soft clients over Kamailio to the IMS. Regards, Serkan CELIK

systemd kamailio.service - RFC Wants=network-online.target
by Kevin Olbrich 08 Nov '18

08 Nov '18

Hi! The systemd kamailio.service file for debian (in my case, it's stretch) has the following unit options set: [Unit] > Description=Kamailio (OpenSER) - the Open Source SIP Server > After=network.target It would be better to change this to: [Unit] > Description=Kamailio (OpenSER) - the Open Source SIP Server > Wants=network-online.target > After=network-online.target Why? With network.target the service starts as soon as the network setup is started, not explicitly after configuring (=IP) it [1]. This creates a race condition on very fast hardware like mine (booting incl. all services takes 10s). Even with static IPs, kamailio often fails directly at boot because eth1 (connection to DB cluster) is not up. [I have never met this problem on systems which ran on HDDs.] Setting "network-online.target" as Wants + After makes sure, Kamailio is started after all interfaces are ready to serve. Units that strictly require a configured network connection should pull in > network-online.target (via a Wants= type dependency) and order themselves > after it. This target unit is intended to pull in a service that delays > further execution until the network is sufficiently set up. What precisely > this requires is left to the implementation of the network managing service. > Perfect example for this is the Shorewall package (firewall solution): [Unit] > Description=Shorewall IPv4 firewall > Wants=network-online.target > After=network-online.target > Conflicts=iptables.service firewalld.service RFC Kind regards Kevin [1] https://www.freedesktop.org/software/systemd/man/systemd.special.html

Phone does not set "Expire-header" but "Contact expire", immediately expires
by Kevin Olbrich 07 Nov '18

07 Nov '18

Hi! I have a phone (Mitel 6930) that does not send an Expire-header but "expire" in Contact during REGISTER: Session Initiation Protocol (REGISTER) > Request-Line: REGISTER sip:pbx.example.com SIP/2.0 > Message Header > Via: SIP/2.0/TLS 192.168.6.16:5061;branch=xxxxxxxxxxxxxxxx;rport > Route: <sip:pbx.example.com;lr=lr;transport=tls> > Max-Forwards: 70 > From: "Example" <sip:121212_6666@pbx.example.com>;tag=b0cec92c3e > To: "Example" <sip:121212_6666@pbx.example.com> > Call-ID: aaaaaaaaaaaaaaaaa > CSeq: 1190442896 REGISTER > Accept-Language: de > Allow: INVITE, ACK, CANCEL, BYE, NOTIFY, REFER, OPTIONS, UPDATE, > PRACK, SUBSCRIBE, INFO, PUBLISH > Allow-Events: talk, hold, conference, LocalModeStatus > Contact: "Example" <sip:121212_6666@192.0.2.1:62336 > >;+sip.instance="<urn:uuid:00000000-0000-1000-8000-08000FB888F5>";expires=300 > Supported: path, gruu > User-Agent: Mitel 6930/5.0.0.2041 > Aastra-Line: 1 > Aastra-Mac: AAAAAAAAAAAA > Content-Length: 0 This results in successful register, kamailio forwards REGISTER to asterisk (endpoint registered) and immediatly kamailio sends a new REGISTER with Expire set to 0 to asterisk: Session Initiation Protocol (REGISTER) > Request-Line: REGISTER sip:192.168.99.112:5060 SIP/2.0 > Message Header > Via: SIP/2.0/UDP 192.168.99.111:5060 > ;branch=z9hG4bK9f9e.599cf243000000000000000000000000.0 > To: <sip:121212_6666@192.168.99.112> > From: <sip:121212_6666@192.168.99.112 > >;tag=7e4f6993bfbf831f6b016fea6683cdca-b98a > CSeq: 10 REGISTER > Call-ID: 2bc5fd1061b31723-1350(a)192.168.99.111 > Max-Forwards: 70 > Content-Length: 0 > User-Agent: kamailio (5.1.6 (x86_64/linux)) > Contact: <sip:121212_6666@192.168.99.111:5060> > Expires: 0 The phone is then unregistered - the phone also shows "no service". It looks like Kamailio generates this message on it's own (and I don't know why). I am still learning to implement kamailio as proxy. Reading the docs, I would expect Kamailio to automatically eval the correct parameter: > If the processed message contains neither Expires HFs nor expires contact > parameters, this value will be used for newly created usrloc records. [1] What did I miss? Phones which use the Expire-header are working fine. Kind regards Kevin [1] default_expires - http://www.kamailio.org/docs/modules/5.2.x/modules/registrar.html

busy lamp field
by Kevin Olbrich 06 Nov '18

06 Nov '18

Hi! Can someone share his kamailio.cfg with working busy lamp field in a kamailio-as-proxy scenario? My config is based on the example shipped with 5.1.x and asterisk as the backend. Calling works fine but PUBLISH / SUBSCRIBE is handled by kamailio itself. I am not sure but this might be the part where I should relay the request to asterisk(?): #!ifdef WITH_PRESENCE > if (!t_newtran()) { > sl_reply_error(); > exit; > } > if(is_method("PUBLISH")) { > handle_publish(); > t_release(); > } else if(is_method("SUBSCRIBE")) { > handle_subscribe(); > t_release(); > } > exit; > #!endif Currently the lights are "broken", some phones show them on, some off. Kind regards Kevin

Development is open for future release v5.3.x series
by Daniel-Constantin Mierla 06 Nov '18

06 Nov '18

Hello, with the creation of branch 5.2 done this morning, the master branch is from now on open for adding new features, to be part of future release series v5.3.x. Any bug fix committed to master that applies to 5.2.x or older stable branches should be backported as usual with git cherry-pick to appropriate branches like 5.2 or 5.1. Expect that v5.2.0 will be released in about 2-3 weeks from now. Based on the workflow used during the past years, the next future release v5.3.0 should be out after another 8-10 months of development, plus 1-2 months of testing, so sometime in the summer or autumn of 2019. Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio World Conference -- www.kamailioworld.com Kamailio Advanced Training, Nov 12-14, 2018, in Berlin -- www.asipto.com
