Prepaid billing solution for a service provider
by Carlo Dimaggio 09 Jan '12

09 Jan '12

Hi all, I'm working in a project for a service provider in which prepaid is an essential requirement. They have about 12000 subscribers. The core infrastructure will be Kamailio+RTPProxy while I have some doubts about the prepaid feature. I'm thinking about a B2BUA (SEMS or Freeswitch) that is called if the user belong to a "prepaid group" and perform authorization and accounting; in this case the SIP flow could be: Kamailio -> B2BUA(Prepaid) -> Kamailio. Is a good choice? At the moment I cannot estimate the effort needed to develop this section (base prepaid feature) of the project... Do you have some hints? What are the prepaid solution implemented by you? Do you use your own developed solution or do you think that is better to choose a commercial solution (that provide also calling-card and other features)? I have seen some commercial products (Portabilling, Jerasoft/Bilberry, ...); what do you think about? Best Regards,

RTPproxy on Kamailio 3.2.1 difficulty.
by nunu abe 06 Jan '12

06 Jan '12

Dear Daniel, Greetings and Happy New year to you all! I would like to thank you very much for your detailed and well structured tutorials on Kamailio. I am resending this email as I sent the earlier one before I was a member of the mailing list and I thought it may have been sent to the spam folder. If not then, I apologize for double posting. I was trying to design a similar scenario like the one " Run your own SIP VoIP service on both IPv4 and IPv6 " as explained on Asipto web-page(http://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6). However I ran into difficulties with rtpproxy. The proxy is not routing media packets as it should. I followed the instruction regarding the kamailio.cfg file and edited the necessary lines according to my settings. I think my problem comes from setting up the rtpproxy. 1. I edited the /etc/default/rtpproxy file. i.e. I uncommented the line - CONTROL_SOCK="unix:/var/run/rtpproxy/rtpproxy.sock" 2. I started the rtpproxy with this command: rtpproxy -F -l ADDR_IPV4 -6 /ADDR_IPV6 . However, after this command the system returns the message : rtpproxy: setbindhost: No address associated with hostname It displays the same message even when I replace ADDR_IPV4 and ADDR_IPV6 with IP addresses. 3. I have also tried using the udp socket:- CONTROL_SOCK=udp:127.0.0.1:22222, of course I have replaced the unix socket by this udp socket in the kamilio.cfg file. So my question is, what did I do wrong with the settings that SIP messages are traversing normal from IPv4 client to IPv6 client and vice versa but media files(RTP packets) are not? The rtpproxy receives the media files from one client but fails to forward them to the other client. Thanks for your help. Maedot

Kamailio 3.2 RTP repacketization
by Arif Tuhin 06 Jan '12

06 Jan '12

Hi,I'm using the new kamailio 3.2 which has some changes in rtpproxy module. And i'm finding it hard to implement a certain configuration. Because of our network infrastructure i have to repackage rtp streams in one direction. Now in kamailio 3.1.5 i used to do this in this way:In main routeroute[RTPPROXY]{if(is_method("BYE"){ unforce_rtp_proxy();else if(is_method("INVITE")){ force_rtp_proxy();}in onreply_route force_rtp_proxy("z160"); Now in kamailio 3.2 the force_rtp_proxy() is replaced by rtpproxy_manage(). Here the script reads like:main routeroute[NATMANAGE] { #!ifdef WITH_NAT if (is_request()) { if(has_totag()) { if(check_route_param("nat=yes")) { setbflag(FLB_NATB); } } } if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB))) return; rtpproxy_manage("z150"); if (is_request()) { if (!has_totag()) { add_rr_param(";nat=yes"); } } if (is_reply()) { if(isbflagset(FLB_NATB)) { fix_nated_contact(); } } #!endif return; onreply_routethis block is called route[NATMANAGE]. Now if i put rtpproxy_manage("z150"), it tries to repackage in both direction which i do not want. So i need to write a separate block for onreply_route instead of calling route[NATMANAGE]. So please help me to write a block for onreply_route.Thanks in advance.

No memory left in send_subscribe (PUA) from update_pua while building the tm dlg_t structure
by laura testi 04 Jan '12

04 Jan '12

Hi, we are using the PUA_XMPP and PUA modules from the master branch. When the modules are started, everything are ok, the presence events from XMPP are sent to kamailio SIP servers (PUBLISH/SUBSCRIBE) and cached in the hash. But when there are several thousands records in the hash tabel, the update_pua function called in the hashT_clean gives a lot of "No memory left" error when the hashT_clean is waked up from the time: ERROR: pua [send_subscribe.c]: No memory left ERROR: pua [pua.c]: while building tm dlg_t structure The failed call is: td = (dlg_t*)pkg_malloc(size); if(td == NULL) { LM_ERR("No memory left\n"); return NULL; } in dlg_t* pua_build_dlg_t(ua_pres_t* presentity) function in send_subscribe.c. The size is about 400 and something... It's strange..... Is it the memory leak in the PUA module? I also try to increase the pkg_memory from 4MB default to 16MB, but it doesn't help. Any Idea? Thanks in advanced Laura

Authentication Feature Question
by Ali Jawad 04 Jan '12

04 Jan '12

Hi I do have 3 Kamailio servers, one for mobile phone registrations, one for softphone registrations and one for SIP device registrations. Each of those devices connects to it's perspective kamailio server sip1.domain.com sip2.domain.com sip3.domain.com All 3 Kamailio servers share the same database, and users can use their kamailio user/pwd on any of the devices, now I want to use encrypted passwords and remove clear text passwords from the database. I did test with one server and all is fine,however if a user want to register from the second kamailio server it does not work, basically because the db domain entry from which the hash is created is sip1.domain.com and stored in the db, while the user connects from to sip2.domain.com this eventually generates a different hash. Is there anyway to overcome this ? Can I exclude Domain from Hash generation ? Any other option that allows me to do the above ? Thanks
