DIAMETER (server & avp helper)
by Steve Bucklin 07 Feb '20

07 Feb '20

Anyone familiar with: ims_diameter_server cdp cdp_avp I have set Kamailio up to connect with SMSC using Diameter. Initially just want to capture requests in JSON and examine. My trace tells me that I am sending a good message for DIRECT_DEBITING (436). I know the ocs module does not support this - only trying to "take apart" the message. When I get the message, I experience the following: Feb 7 13:07:58 ip-172-31-45-179 /sbin/kamailio[18048]: ERROR: cdp [diameter_avp.c:645]: AAAUngroupAVPS(): hss3g_ungroup_avps: source buffer to short!! Cannot read the whole AVP header! Feb 7 13:07:58 ip-172-31-45-179 /sbin/kamailio[18048]: CRITICAL: cdp [diameter_avp.c:702]: AAAUngroupAVPS(): AVP:<> I suspect this is due to vendor, but not experienced here. The docs seem to suggest the 3gpp is supported, and the diameter xml is set for 0 & 10415? Steve

Best practice to figure out one way rtp delay
by Karsten Horsmann 06 Feb '20

06 Feb '20

Hi List, I have a new setup with two Kamailios installations. One serves siptrunks from the internet and one is for internal routing. So far so good. At the end I have an 3rd party b2bua that receives and sends calls via the both Kamailios. For testing purposes I setup an freeswitch with beep and then echo application to the caller. My call flow are like this Call 1 to kam1 sbc then internal kam2 and b2bua. B2bua make then new call no 2 vice versa to PSTN freeswitch with echo. After this b2bua bridges the calls together. This generates for the caller an beep and echo. The interesting thing is now, that Call 1 gets an hearable delay of 1 second. But only in the rtp steam from me to the caller. The second calls seems equal of timing. Since is a really new complete setup of hardware and stuff, the question of its working before is answered with an no. Now my question to you guys. How can I get an measurable method to finding the delaying parts (could be network, servers, applications etc). Only capturing on one place don't did the trick for me. Thanks for your hints Cheers Karsten

Binary Websocket messages
by Andre Pires dos Santos 06 Feb '20

06 Feb '20

Hello guys, we are new to kamailio so sorry basic or wrong points. We started using kamailio 5.3.2 and rtpengine as our sip to webrtc solution and SIP.js as webrtc client. We noticed that most of the times webrtc client receives UTF-8 messages. But sometimes webrtc client receives binary messages. When we get binary messages SIP.js cannot parse the message. I couldn't find how to force kamailio to send only UTF-8 messages. Is it possible? We have other issues but I think it will be better for the list to break other points in different messages. Thanks! Santos

IMS RX AAR issues
by Pafel 06 Feb '20

06 Feb '20

Hello, I am using kamailio 5.3 + rtpengine module + sipwise rtpengine in a IMS test environment. I have and issue with ims_qos module and Rx AAR command. PCSCF is configured with #!define WITH_RX ##!define WITH_RX_REG #!define WITH_RX_CALL I have 2 test phones connected. Both of them use ipv6. PCSCF has ipv4 and ipv6 address. All other nodes - SCSCF, ICSCF use ipv4. Simple scenario UE1 calls UE2. UE2 is replying with 183 session progress and then RX AAR is sent by PCSCF to PCRF/PGW. The problem is that AVPs Media-Sub-Component Flow-Description include ipv4 address of the proxy and ipv6 address of the UE. Example: permit out 17 from 192.168.1.1 34998 to fd18::1:2dca:3303:1286:257d 50010 permit in 17 from fd18::1:2dca:3303:1286:257d 50010 to 192.168.1.1 34998 But this is not acceptable for the PGW (different ip versions). The SDP between UE and PCSCF is rewritten by rtpengine/sipwise. Looking at the ims_qos module I found that the address of the proxy is taken from the session original request SDP media ip/port. Having in mind that rtpengine/sipwise proxy is rewritting it is there any way I can set the correct ipv6 address and port of the proxy? I've tried to get the rewritten media address from SDP (in logs) but without success: if(sdp_get_line_startswith("$avp(cline)", "c=")) { xlog("L_INFO", "SDP media ip: $(avp(cline){s.select,2, })\n"); } if(sdp_get_line_startswith("$avp(mline)", "m=")) { xlog("L_INFO", "SDP media port: $(avp(mline){s.select,1, })\n"); } I am always getting the ipv4 media address and port of the proxy. Any idea how I can set and use the rewritten by the rtpengine/sipwise media ip and proxy for the RX AAR? Thanks in advance, Pavel Siderov

Pre-built Debian Package for Kemix Module?
by Yufei Tao 05 Feb '20

05 Feb '20

Hi, I am trying to use KEMI lua that needs kemix module (for KSR.kx.<...>). I wonder if there is any pre-built Debian package that include the kemix module, something like kamailio-<...>-modules, that I can install? Or do I need to build from source with kemix in included_modules? On a related question, for the kamailio-<...>-modules packages how do I find out what modules are included in each of these package? E.g. things like kamailio-lua-modules, kamailio-mysql-modules etc. are easy to guess, while kamailio-nth, kamailio-utils-modules etc. are not so easy. Thank you! Yufei

config file packaging
by Sergey Safarov 05 Feb '20

05 Feb '20

Hi At present time kamailio config file packaged with kamailio binaries. So projects that use kamailio cannot simple package "/etc/kamailio/kamailio.cfg" file. This leads to packages conflict on RPM dists. As options we can separate "kamailio default config" and "kamailio binaries" to packages. 1) kamailio-cfg-default 2) kamailio-base This allow not install "kamailio-default" config when project provide own config file. For backward compatibility we create "kamailio" empty package that have two dependencies "kamailio-cfg-default" and "kamailio-base". What you think?

How to implement simple presence in kamailio active-active cluster.
by Zhan Bazarov 05 Feb '20

05 Feb '20

Hello! We have next setup, which I've desribed in: http://sip-router.1086192.n5.nabble.com/Bad-request-when-INVITE-relayed-to-… Presence works fine in setup with single kamailio, without any loaded presence modules... So, I want to something wtih SUBSCRIBE and NOTIFY methods... But when I making a relay on second kamailio instance I receive 407 proxy auth required from this instance... So, its how I'm trying to implement this: part of code from route[LOCATION] case -2: if (is_method("SUBSCRIBE|NOTIFY")) { $ru = "sip:" + $tU + "@" + "ip_of_second_kam:5078"; t_relay("ip_of_second_kam", 5078); exit; } else { send_reply("405", "Method Not Allowed"); exit; } Any ideas how I can do that? Thanks. -- Sent from: http://sip-router.1086192.n5.nabble.com/Users-f3.html
