Next online devel meeting - Wed, Nov 25, 2020, 15:00UTC

by Daniel-Constantin Mierla

Hello, in order to plan the roadmap to next major release, it is time to organize another online devel meeting, so the developers and community members can syncronize and plan what should be done till Kamailio v5.5 will be out. Because freenode.net service is requiring user registration to join IRC channels on their servers, the meeting will be done on a matrix chat room. More details are in the wiki page of the event, available at: * https://www.kamailio.org/wiki/devel/irc-meetings/2020b Feel free to add there topics that you want to be discussed. The proposed date is next Wednesday, November 25, 2020, at 15:00UTC (15:00 London/Dublin, 16:00 most of West Europe, 10:00 New York), but other dates can be proposed if they suit for more participants. Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda

How to route to calls to asterisk

by Mihai Cezar

Hi all, I need some help on getting to work my scenario: I have 3 asterisk servers, and every agents (soft phones like zoiper) is connecting to which server they need by contacting the PublicIP of each server. (the problem is that I need to reuse the IP address on others servers) . I want if is possible to use a proxy like "haproxy" but for sip to redirect the agents (softphones), to their coresponding server. For example: - james(a)ast.example.com -> must register to asterisk server 1, - sarah(a)ast2.exampe.com -> must register to asterisk server 2 - andy(a)ast3.example.com-> must register to asterisk server 3 ast.example.com, ast2.example.com, ast3.example.com = will share all the same ip, when the request arrives in the proxy it should check the vhost and redirect to the coresponding server for registering. Any hints and how to do this scenario?

textops.subst_uri does not change all branches

by Anthony Alba

Hello kamailioers, Version 5.4.2. I have a R-URI that I need to change TLS -> TCP in all branches. I do this in request route before t_relay: // AoR has multiple contacts, all with transport=TLS route[REQUEST] { textops.subst_uri("/transport=TLS/transport=TCP/i") //parallel forking //why doesn't this change all branches? t_relay() } If I print out the R-URI in the branch route, I see that only the first R-URI is changed, in the other branches the R-URI transport=TLS is not changed to transport=TCP. Any suggestions on how to get this to work across all Contact addresses? Thanks Anthony Alba

Issue with ca-list

by George Goglidze

Hi Folks, I was wondering if somebody could help me with an issue. I’m a newbie here, just installing Kamailio sip server. I’ve enabled TLS, and am trying create a SIP Trunk to external SIP Service which is TLS enabled port 5061. I’ve configured the following in tls.cfg: [server:default] method = TLSv1.2+ verify_certificate = yes require_certificate = yes private_key = /etc/kamailio/certs/sbc-private.pem certificate = /etc/kamailio/certs/godaddy.pem ca_list = /etc/kamailio/certs/calist.pem In the section above – ca_list = calist.pem contains all the CA’s and Subordinates of the destination server. Private_key and certificate are of my own server (public godaddy signed) [client:default] method = TLSv1.2+ verify_certificate = yes require_certificate = yes private_key = /etc/kamailio/certs/sbc-private.pem certificate = /etc/kamailio/certs/godaddy.pem ca_list = /etc/kamailio/certs/godaddyca.pem In the section above the ca_list is godaddy’s ca and subordinate. In the wireshark I can see that I’m sending out SIP OPTIONS PING (I’m using dispatcher module). Then the server replies with tls SERVER HELLO which includes it’s certificate But for some reason we are rejecting it: Alert (level: fatal, Description: Unknown CA) How should I set this up to make sure the remote server CA’s are verified? Thank you,

t_uac_send function with From tag

by João Vitor Arruda

Hello, I'm trying to use the function t_uac_send inside a failure_route as described in https://kamailio.org/docs/modules/5.3.x/modules/tm.html#tm.f.t_uac_send to send a CANCEL out. Although the documentation says "it can include From/To tags" i was not able to get the from tag provided to be used. Another random generated one is used. I've tried the following format without success: t_uac_send("CANCEL", "$ru", "", "", "From: <$fu>;tag=$ft\r\nTo: $tu\r\nCall-ID: $ci\r\n", "") t_uac_send("CANCEL", "$ru", "", "", "From: $fu;tag=$ft\r\nTo: $tu\r\nCall-ID: $ci\r\n", "") t_uac_send("CANCEL", "$ru", "", "", "From: bob(a)kamailio.org;tag=2w3e\r\nTo: $tu\r\nCall-ID: $ci\r\n", "") In the last one which is copied from the documentation that is how the >From header going out looks like: From: <bob(a)kamailio.org;tag=2w3e>;tag=3393f0703fb0ccaca74109ff37de39f5-36d71ef0 Any tips on how to get the From tag passed to the function to be used? Thanks, Joao Arruda

Kamailio suddenly stopes responding to sip messages

by Uttam Giri

Hi, We are using Kamailio with Jitsi client where we observed sometimes Kamailio stops responding to sip messages. As a result, my Jitsi client goes offline and never back online. Also in the Kamailio syslog there are no error logs(debug enabled) related to this issue. As a temporary workaround, we had to restart the Kamailio server all the time. Does anyone observed a similar issue and can suggest any resolution.
