Unable to get avp value in response

I am trying to set a value to an avp on the request route, but when I try to read the avp on the reply route I always get nil. On the route I have this: KSR.xlog.xinfo("invite_request: ********** Setting avp test\n") KSR.pv.seti("$avp(test)", 1) KSR.xlog.xinfo("invite_request: **** " .. tostring(KSR.pv.get("$avp(test)")).."\n") On the reply route I have this: KSR.xlog.xinfo("response_invite: **** " .. tostring(KSR.pv.get("$avp(test)")).."\n") In the logs I see on the INVITE: Aug 8 13:49:15 test /usr/sbin/kamailio[1927947]: INFO: [a0748d39-3f17-4080-b5ed-0a6b7019cb95 INVITE 1]invite_request: ********** Setting avp test Aug 8 13:49:15 test /usr/sbin/kamailio[1927947]: INFO: [a0748d39-3f17-4080-b5ed-0a6b7019cb95 INVITE 1]invite_request: **** 1 ... ...

Kamailio behind TLS-TCP load balancer

by David Villasmil

Hello all, I’m having lots of problems when trying to configure Kamailio behind an AWS tls load balancer to offload tls and receive on tcp on Kamailio. Everything else inside is UDP. I found I need to manually add record-route presets every time and invite comes in. And when trying to forward an ACK to the client via tls/tcp load balancer Kamailio complaint the socket is not TLS so it fails. Is there a simpler way of doing this via some parameters I don’t know? Thanks for helping me with this! David -- Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Kamailio dns-failover / dns-loadbalancing with slow responding client.

by Mattis Lind

Hello! I am looking into a problem where we have Kamailio forwarding calls to two or more "recording-clients". I will try my best to describe the problem and would appreciate it if someone has an idea what to do. Please feel free to ask if you think I have forgotten to describe something that might be important or something is unclear in what I have written. We use use_dns_failover=yes and dns_srv_lb=yes so calls get load balancing to the "recording-clients". There is also the t_set_fr(60000,1000) parameter set so that if there is no response within 1 second it would try the next recording-client. The SRV record points to two or more recording clients. It now happens that the recording-clients sometimes have some kind of temporary problem so it will respond with a 503 after 5 seconds. What happens is that after the 1 second timeout trying to get the INVITE through to the first recording-client Kamailio will internally generate a 408. This will cause it to failover to another recording-client which happily takes care of the INVITE and responds properly with a 200 OK. Everything would have been just fine except for the fact that the first recording-client is just slow and finally responds with a 503. This 503 is not relayed backwards since a 200 has already been forwarded back to the caller. But when receiving the 503 Kamailio will initiate a new INVITE which is trying to set up a new call to a recording client. It looks like it is doing a new failover regardless if it already has done a failover for this failed transaction. I don't want Kamailio to send that last INVITE when receiving the 503. How can I configure Kamailio to disregard the last 503 (except for responding with an ACK) and not initiate a new INVITE? I have tried a lot of different changes to the configuration but failed to achieve this, unfortunately. Do I need to use the dispatcher module to achieve this? /Mattis
