kamailio passthrough user auth
by Kai Arif 05 Feb '15

05 Feb '15

Hi, I have to implement a rather uncommon SIP setup and wanted to ask, if it is even possible with Kamailio. We are among other things a VoIP-provider for a couple of hundred customers. Right now we use a rather old piece of software as a SIP-server, that was written in-house and is deeply integrated in our user interfaces and the billing system and can't be replaced easily. But now we need to make some modifications because our PSTN-gateway-provider is changing things. The idea is to use Kamailio as proxy in front of our old SIP-server. But to do this we need to pass through the REGISTER requests of our users to the old SIP-server. So the question is if Kamailio supports this kind of passthrough and I would also be rely grateful for a piece of example config, if somebody already has a similar setup running. So far neither the documentation nor google have been very helpful.

Does the event_route[tm:local-request] support stateless forwarding configured in the script?
by Klaus Feichtinger 05 Feb '15

05 Feb '15

Hello, I´m searching for a way to keep track about success or failure of locally generated SUBSCRIBE transactions, which are typically triggered by the RLS module. In case that a subscription is rejected by the subscribee with any negative response code or the transaction is timing out, I have to trigger a specific action (e.g. sending a PUBLISH message to another user agent). This seems to be not so easy.... As Kamailio does not support referencing a failure_route to locally generated requests, I had the idea to "forward()" locally generated requests in the event_route "tm:local-request" to itself and handle the forwarded requests in the standard request_route, which would offer all usual options. But that seems not to be supported / allowed by Kamailio, as I have in practical tests (1) an outgoing request that is sent to the original Destination-URI (with a malformed "Content-Length" SIP hdr) and (2) the second request that is sent to the manual target (loop). I´ve found in the mailing list that elder Kamailio versions did not support any common way for this feature. However, can anybody give m a hint if / how this could eventually be solved with the event_route or in any alternative route? It seems that the Kamailio internally generated requests are still below the radar of TM or any other route blocks except tm:local-request..... regards, Klaus

Out of Memory Error in Kamailio
by Neeraj Swarnkar 05 Feb '15

Hi Guys, I am using Kamailio-4.2.1. Earlier I was using shared memory of 16GB, which started popping out of memory error, within few seconds of generating load from sipp. I used sipp following command: sipp -s 999999999999 MY_KAM_IP -l 2500 -r 50 *Error coming is :* *Feb 4 14:12:23 kamailio_us_ha1 /usr/local/sbin/kamailio[27389]: ERROR: tm [t_reply.c:1946]: relay_reply(): ERROR: relay_reply: cannot alloc reply shmem* After changing the shared memory to 1 GB, this error came quite late when generate load at 200 CPS. sipp -s 999999999999MY_KAM_IP -l 2500 -r 200 Why this is happening?

Issue is that i can not route calls to the PSTN. I am using the default configuration version: kamailio 4.2.2 (i386/linux) OS: Debian wheezy -- Kind regards, Brian Linux registered user: . #565878 www.brianechesa.com

RTPEngine - No support for kernel packet forwarding available
by Muhammad Shahzad 05 Feb '15

05 Feb '15

Hi, I have latest stable release of RTPEngine deployed in a virtual machine (KVM) along with Kamailio v4.2. All is working fine except i see this message in RTPEngine logs, -- rtpengine[16455]: [82qrjq0hdtt45afbqo98 port 40960] Kernelizing media stream rtpengine[16455]: [82qrjq0hdtt45afbqo98 port 40960] No support for kernel packet forwarding available -- using lsmod command i see that module xt_RTPENGINE is load. -- Module Size Used by iptable_mangle 12488 0 xt_RTPENGINE 22068 3 iptable_nat 12800 0 nf_nat 17924 1 iptable_nat ... -- Also the iptables rule for RTPEngine exists, i.e. -- Chain INPUT (policy ACCEPT 224K packets, 37M bytes) pkts bytes target prot opt in out source destination 224K 37M rtpengine all -- any any anywhere anywhere Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 224K packets, 37M bytes) pkts bytes target prot opt in out source destination Chain rtpengine (1 references) pkts bytes target prot opt in out source destination 2022 414K RTPENGINE udp -- any any anywhere anywhere RTPENGINE id:0 -- Yet still RTPEngine is not able to kernelize the RTP stream and does user-space packet forwarding? Can you guys suggest what could be wrong here? Thank you.

[OT] ssl certificates updated for kamailio.org
by Daniel-Constantin Mierla 03 Feb '15

03 Feb '15

Hello, short note to say that I updated the ssl certificates for kamailio.org web site. They are issued by cacert.org, which is probably not trusted by most of the browsers, but they are well known in the open source environment. If you get a warning about certificate change and the issuer is cacert.org, then you should be safe to login over https (e.g., to edit the wiki pages). Cheers, Daniel -- Daniel-Constantin Mierla http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda
