Kamailio static comilation
by Pratik V Patel 01 Aug '16

01 Aug '16

Hello all, I want to compile kamailio open source statically. I want to remove dependency for dynamic shared libraries. can anyone help me to get out of it? I have tried by chang in Makefiles but it does not work. What the meaning of "static_modules" during compilation. It is still generating dynamic shared libraries. Please do needful. -- Thanks And Regards, Pratik V. Patel Ext: 558

I did not find in textops or utils modules a function to check if a string is an ipv4 address. Does it exist somewhere else? -- Juha

I'm getting below every 2-3 weeks someone tried to connect through the CLi of RTPengine and crashed Rtpengine. Anyone knows what to make out of this ?

Kamailio LB: how to get Asterisk to do the RTP
by Tickling Contest 28 Jul '16

28 Jul '16

With the help of members from this mailing list (many thanks!), I finally got Asterisk fronted by Kamailio for LB and REGISTERs and I am able to make a call using the setup that looks like this: [Kamailio 4.4.2]<->[Asterisk 13.7.2] Kamailio manages REGISTERs, but also forwarding them to Asterisk. I am able to make a call, but I get only one way audio or no audio depending on which client made the call (SipDroid->Zoiper I hear one way audio on Zoiper, but no audio if the call is made the other way). I noticed that Kamailio forced direct media between the endpoints in this situation, but my application really needs Asterisk to handle it. How do I do this? Should I start by forwarding INVITEs to Asterisk? How do I do that? Any help is appreciated. Thanks!

undefined symbol: EVP_sha1 when using outbound module
by Francisco Burgos 28 Jul '16

28 Jul '16

Hi, I am trying to use kamailio as an edge proxy to forward requests and media to an sbc. when compiling the cfg file included on the examples. i get: undefined symbol: EVP_sha1 I believe this problem is being caused by the outbound module and after some research i managed to read that it is caused by the linking between the gcc libcrypto. I would like some help since this project requires urgency. Thanks in advance.

TM: t_relay([host, port]) DNS Queries
by Louis-Olivier Roof 27 Jul '16

27 Jul '16

Dear Kamailio users, Ref: http://kamailio.org/docs/modules/4.2.x/modules/tm.html#tm.f.t_relay Using t_relay([host, port]) to relay messages to a specific host does not seem to generate DNS queries to the said host after Kamailio has initially processed the configuration file. It resolves the host once at startup then continues using the same IP after. Is that expected behavior? Anyone has had this issue before and found a way to work around it? Note that for this specific application, messages need to be relayed to a specified host (different from current R-URI) and this host needs to be resolved by DNS during normal operation, not only at startup. Thanks! Louis-Olivier

Checking for 200ok Response to a REGISTER request kamailio-Asterisk
by Jonathan Hunter 27 Jul '16

27 Jul '16

Hi Guys, So currently on our network we have a kamailio server which users register against, we then replicate the register messages to 2 Asterisk boxes sat behind it so that all entities are aware of the registration state of the users. REGISTER--->KAMAILIO---->ASTERISK A ---->ASTERISK B With a REGISTER---200OK exchange between Kamailio and Asterisk. We have an issue where at some points the Asterisk servers when under load dont respond with a 200 ok(something being investigated) to the register messages sent to kamailio, so I am just working on some logic for the register message to be resent using the t_replicate and t_set_fr functions. This works well should both Asterisk servers not respond, however, as I am using replicate and it is parallel forking, if say Asterisk A answers first and is available with a 200ok then that in turn cancels the register message branch being sent to Asterisk B(which I know is fine), however there could be a scenario where Asterisk B doesnt respond, and we wont know about it to try and resend the Register message, as the branch is cancelled. Hope that makes sense? I am looking at checking that both the Asterisk servers have responded and sent a 200ok, which I can grab in an onreply route but Im just wondering if someone has done something similar or has any suggestions as it is tricky to achieve currently. I have also thought about stateless working but I really need kamailio to keep retransmitting the register until it gets a response. Many thanks Jon

CANCEL message within transaction not being relayed
by Ali Soltani 26 Jul '16

26 Jul '16

Hi, We tested the following on Kamailio 3.x and 4.x and observed the same behavior. INVITE and CANCEL are sent to Kamailo from the same source within the same transaction. (branch value in the first via header are the same in both INVITE and CANCEL message. Also FROM and TO header are same as well). However, Kamailio does not relay CANCEL message. UAC keep sending CANCEL till timeout. Apparently, t_check_trans() returns false. Can anyone help me on this issue on why Kamailio does not relay CANCEL message?
