Kamailio ds_ping_interval Performance
by Atul Thosar 10 Apr '18

10 Apr '18

Hi All, I am using Kamailio ** *v4.4.x* to load balanced traffic to FreeSWITCH servers. I have query regarding ds_ping_interval and ds_probing_threshold. We have very high traffic (around 200-400 (CPS) calls per sec) hitting on Kamailio which then distribute it to 2-3 FreeSWITCH servers. What is the optimal value should I set to ds_ping_interval and ds_probing_threshold? If I set ds_ping_interval=2 and ds_probing_threshold=1 then in every 2 sec, I would come to know if my FreeSWITCH server is down/up. But by setting such low values, I afraid there would be lot of SIP traffic on network. If I set high (say ds_probing_threshold=5) then I may loose high number of calls (200 CPS, I will loose 1000 calls) in case FreeSWITCH server is down. As I said earlier we have very high traffic hitting on Kamailio, can't kamailio use INVITE itself to probe FreeSWITCH server is down/up? In case of low traffic can't it switch over to OPTION mechanism? -- Thanks in Advance , Atul

Calling a mobile SIP client, which needs to update the registration
by Ulrich Henning 09 Apr '18

09 Apr '18

Hi everybody, I am trying to call a sip client on a mobile cellphone, which is registered fine at my Kamailio instance. Everything is working fine if the phone is awake and the mobile app is not sleeping (e.g. energy saving by OS). If the device is sleeping, the cellphone gets a wakeup request call via apple push kit and wakes the app. Currently my app is doing a Register after each wakeup, because the device does not know if the cellular network changed (external IPv4 address with Carrier Grade NAT). At this point an incoming call already got routed to any existing user registrations in userloc db. In this case, if the cellular provided network address changed, the sip client on the device won't receive any invite of this last call. Instead all last known Contact-URIs are tried to be called until this sip invite times out because no response message is received back in time. I tried to delay the incoming invite message, but this doesn't seem the right way to go, since I can't know if the mobile device is actually reachable and this method would potentially delay every call. What is the best approach to solve this issue? I am looking forward for any comment or suggestion. BR, Henning

MSILO: SIP stored offline MESSAGE repetitive delivery
by Abdul Basit 09 Apr '18

09 Apr '18

Hi team, I am facing an issue while setting up IM server based on kamailio. SIP-SIP online messaging is fine. For offline messaging i am using msilo module which is storing offline messages in 'silo' table. As B-party come online ... it receive offline messages stored in database. But *Problem is*.. these messages will deliver to B-party as many time it REGISTER online. How can I configure msilo module to mark messages delivery status? or how can i delete the delivered messages so that there will be no chance of delivering them again on next REGISTER? Message parts of kamailio.cfg are .... /* add local domain aliases */ alias="192.168.10.18" port=9060 # ----- msilo params ----- modparam("msilo", "db_url", DBURL) modparam("msilo", "db_table", "silo") modparam("msilo", "sc_mid", "id") modparam("msilo","from_address","sip:registrar@192.168.10.18:9060") modparam("msilo","contact_hdr","Contact: registrar@192.168.10.18:9060; msilo=yes\r\n") modparam("msilo","content_type_hdr","Content-Type: text/plain\r\n") ........ route[MSILO_MESSAGE] { if (!is_method("MESSAGE")) return; xlogl("L_NOTICE", "[$rm] r-uri: $ru d-uri: $du \n"); if (lookup("location")) { xlogl("L_NOTICE", "[$rm] -> loaction found.

Problem capturing packets from kamailio to homer sip-capture
by Arik Halperin 07 Apr '18

07 Apr '18

Hello, My kamailio is listening to TCP, so when I try to duplicate packets to homer, It tries to send them as TCP. From the log I see: Apr 5 08:21:45 kamprod /usr/local/sbin/kamailio[16309]: ERROR: <core> [core/forward.c:181]: get_out_socket(): no socket found Apr 5 08:21:45 kamprod /usr/local/sbin/kamailio[16309]: ERROR: <core> [core/forward.c:183]: get_out_socket(): no corresponding socket found for(udp:10.168.10.229:5090) Apr 5 08:21:45 kamprod /usr/local/sbin/kamailio[16309]: ERROR: siptrace [siptrace.c:1940]: trace_send_hep2_duplicate(): can't forward to af 2, proto 1 no correspondi Which is rather strange to me, because the protocol is defined to be UDP for HEP: corresponding socket found for(udp:10.168.10.229:5090) How can I fix this? Thanks, Arik

Dialog Profile Value Name Limit
by Duarte Rocha 06 Apr '18

06 Apr '18

Greetings, I'm using the Dialog module and the profile functions in order to limit the number of channels that a Calling Number can use. I'm using profile with values and the number in E164. However it doesn't work correctly and the value are not correctly updated. I've tried to give a a value with only 5 digits and everything seems to work fine. Does the set_dlg_profile and unset_dlg_profile have a size limit for it's value ? Thanks

Hello Sir, I need your expertise for kamailio cdr generation in seconds format. I have a requirement to generate cdr duration in second format.Now I am getting second.milliseconds format.Below is the log where duration is 18.676 but I want this to be 19.(suppose where duration =18.234, I need it to be 18).

Install IMS Modules over KAMAILIO 5.1
by Roi Arias Salve 06 Apr '18

06 Apr '18

Hi all. I would like to thank you all the documents you have to install a Kamailio server. It's quite easy and fast. Currently I'm working on Azure, witha Debian 9 OS, and I'd followed the instructions to install the Kamailio OPENSER, and everything Works perfect. But now I'm stuck on my next step. I would like to install all the IMS components, P-cscf/I-cscf/S-cscf/Fhoss following this document https://www.kamailio.org/wiki/tutorials/ims/installation-howto But, I have no success. Maybe I've a mistake on the selection for the Debian OS installed on the server. I say this because of this sentence: " Note: This document is work in progress and yet unfinished! This is a short installation howto for Debian Wheezy (stable). " So, I asume that maybe here I have a problem with the OS version, I'll try to summarize where I have problems: 1.- I've installed the , P-cscf/I-cscf/S-cscf not a problem. 2.- I am not able to follow this steps related to the repository: First, install the Key for our repository: wget -O - http://repository.ng-voice.com/PublicKey | apt-key add - Then add the repository to your "/etc/apt/sources.list": echo "deb http://repository.ng-voice.com jessie ims rtpproxy" >> /etc/apt/sources.list and also I have problems with this action over the repository Note: You will need to add the "non-free" packages to your repository: deb http://ftp.de.debian.org/debian lenny main non-free deb http://security.debian.org/ lenny/updates main non-free 3.- I decided to install directly the modules from an apt-get install action, because I followed the instructions on the Log created on the Kamailio starting box, where you can find all the steps related to IMS modules, and the suggestion there it is to compile your own modules. On this step I detected a problem related with the dialog_ng module, according to the .log document on the Starting box, you have to include all the modules before you execute the make all instruction: modify modules.lst for included modules and excluded modules (use saved file) - include: ims_auth ims_charging ims_icscf ims_isc ims_qos ims_registrar_pcscf ims_registrar_scscf ims_usrloc_pcscf ims_usrloc_scscf dialog_ng cdp cdp_avp 4.- After this issue, I tried to install FHOSS, but here I can't go further, I am not able to compile it, neither doing my own compilation following this step ant compile deploy | tee ant_compile_deploy.txt nor following apt-get install openimscore-fhoss I was no table to get connected to the repository, so I can't go further. I'm sorry for all this information, can anyone help? Any suggestion?

SIPT append_body_part \x00 how to?..
by Sergey Basov 06 Apr '18

06 Apr '18

Hi All! I have some troubles with encoding hex string to use as ISUP part. I have next line: append_body_part("\x01\x10\x48*\x00*\x0a*\x00* \x02\x09\x07\x03\x90\x90\x13\x71\x32\x20\x0a\x04\x02\x13\x73\x12*\x00* ","application/isup;version=itu-t92+","signal;handling=optional"); Problem is in the *\x00 *kamailio reads this string till first \x00 May be there is some workaround? Currently I have added some C code into SIPT module to change values in this pisitions first to 00 then make other changes. My current input string is append_body_part("\x01\x10\x48*\x01*\x0a*\x01* \x02\x09\x07\x03\x90\x90\x13\x71\x32\x20\x0a\x04\x02\x13\x73\x12*\x01* ","application/isup;version=itu-t92+","signal;handling=optional"); I first make replacement \x01 to \x00 while executing sipt_destination May be there is better solution? Thank you. -- Best regards, Sergey Basov e-mail: sergey.v.basov(a)gmail.com
