Unable to get avp value in response
by peter＠alienzombie.co.uk 17 Aug '23

17 Aug '23

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 17 Aug '23

17 Aug '23

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 14 Aug '23

14 Aug '23

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

Modify To URI in Multiple Choices
by Ali Taher 11 Aug '23

11 Aug '23

Hello, I'm using Kamailio as SIP redirect where SBC sends INVITE packet to kamailio and "302","Multiple Choices" is sent back to SBC. What I want is to modify the URI part in the To header of the Multiple Choices packet sent from kamailio. I tried to use uac_replace_to("","sip:$var(cdpn)@$td") where $var(cdpn) is already defined in the routing logic, but it's not reflected and the original TO URI is sent instead. Any help to handle this issue is much appreciated. Regards,

how to get value of next hop
by Sergey Safarov 10 Aug '23

10 Aug '23

I receiving INVITE with two Route header (no to tag). First Route header is my Kamailio host. Second Route header is next hop after Kamailio. I need to get value of next hop. I tried to use "$route_uri" after "loose_route" but his deos works. "$route_uri" always use top Route header. But in the INVITE first Route header is Kamailio host. Is any change to get top Route header after "loose_route"?

Kamailio-asterisk BYE
by Dr. Barabás Péter 09 Aug '23

09 Aug '23

Hello, we work on a mobile softphone which connects to asterisk through kamailio. Almost everything is fine except one thing. Asterisk allows only one registration to an AOR. In mobile environment network can change, register/unregister can be called frequently in foreground/background cases. Kamailio forwards every request to asterisk. Until I have only one connection between kamailio – asterisk, everything is fine. The next situation is problematic: 1. Client A and client B register to asterisk through kamailio. –> there will be one connection between kamailio and asterisk 2. Client A calls client B. • one connection exist still 3. If client A terminates the call -> one connection remains. It is okay. 4. If client B terminates the call -> a new connection appears (kamailio IP with new port) After case 4 If I try to register again, I got 403 from asterisk, since the setting of asterisk does not allowed to register from different IP:port for the same AOR. (this behaviour cannot be changed now). The question: is there any setting/config exist in kamailio not to create new connection for a BYE in above case. Thanks in advance for your reply. Peter
