Re: [Kamailio-Users] Load Based Load Balancing

Please keep the list in your replies. Check the dialog documentation carefully. It is all explained there: how to add dialogs into a profile and retrieve the them. The dialog profiles are stored into memory for fast access.

[Serusers] SER fail authentication using RADIUS
by Leon Li 22 May '09

22 May '09

Hi, I got the following error when using FreeRADIUS to authenticate SER registration. May 21 04:46:57 ser[3352]: REGISTER May 21 04:46:57 ser[3352]: REGISTER: challenging user May 21 04:46:57 ser[3354]: REGISTER May 21 04:46:57 ser[3354]: pre_auth(): Credentials received are not filled properly What does this mean? Also, I don't see any RADIUS traffic generated by SER. Please assist. Thanks Leon

[Kamailio-Users] Dialog profile size not resetting in 1.4.4.
by Alex Balashov 21 May '09

21 May '09

Greetings, I've run into an issue with 1.4.4 in which the following appears to be happening, and I'm yet to determine the cause: The total amount of open inbound calls (dialogs) is tracked with the dialog module by putting them in a global profile. Because of a segfault bug with profiles with "no values," a workaround is used wherein a profile "with" values is created and the hash key is always the same value (i.e. "1"). The dialog tracking flag is 2: modparam("dialog", "dlg_flag", 2) And profile looks like this: modparam("dialog", "profiles_with_value", "globalinbound;specificinbound") Anyway, inbound INVITEs get handed off to a route (route[1]) that performs some logic like this: route[1] { # Check if DID is assigned to an account with database # and store value in AVP, along with other values. if($avp(S:did_assigned) == "0") { sl_send_reply("404", "Not Found"); exit; } get_profile_size("specificinbound", "$avp(S:account_id)", "$var(a_concurrent_calls)"); if($var(a_concurrent_calls) >= $avp(S:port_limit)) { sl_send_reply("486", "Busy"); exit; } setflag(2); # Track dialog. set_dlg_profile("globalinbound", "1"); set_dlg_profile("specificinbound", "$avp(S:account_id)"); } What appears to be happening is that calls coming into unassigned numbers ($avp(S:did_assigned) == "0") increase the size of the "globalinbound" profile, which is something of a mystery to me since I am neither setting flag 2 nor calling set_dlg_profile() until further down in the logic! And after the 404 Not Found reply is sent, the profile size is not decremented. Is the use of statefully tracked replies (t_reply()) required in order to propagate dialog state through to the dialog module? My impression is this was not the case. More pressing concern is that profile size is increased and not decreased; in my interpretation, such calls should not be added to the 'globalinbound' profile at all. I have not had the opportunity to try to reproduce this with 1.5.x.

[Kamailio-Users] "Detached" timer messages.
by Alex Balashov 21 May '09

21 May '09

Greetings, I was wondering if someone fluent in the anatomy of the TM module can tell me what this condition actually implies in a commonsensical sort of way, from a user perspective -- it is on line 861 in modules/tm/timer.c: /* check first if we are on the "detached" timer_routine list, * if so do nothing, the timer is not valid anymore * (sideffect: reset_timer ; set_timer is not safe, a reseted timer * might be lost, depending on this race condition ) */ if (new_tl->timer_list==DETACHED_LIST){ LM_CRIT("set_timer for %d list called on a \"detached\" " "timer -- ignoring: %p\n", list_id, new_tl); goto end; } Reason I am wondering is that I got a few of these error messages in my logs: May 20 18:23:50 ser1 /usr/local/sbin/kamailio[25232]: CRITICAL:tm:set_timer: set_timer for 1 list called on a "detached" timer -- ignoring: 0x2a96cc0d50 And was not sure what to make of them.

[Kamailio-Users] Mailing list questions

Is there an easier way to search through the mailing list other than going to http://lists.kamailio.org/pipermail/users/, and searching in my Firefox based on the subject name? Thanks

[Kamailio-Users] RLS - is rls-services supported ?
by Pascal Maugeri 21 May '09

21 May '09

Hi I'm doing an integration of the RLS module for Kamailio 1.5 and a third-party XCAP server. I see that when my client sends a SIP SUBSCRIBE to a list that is defined into the document rls-services, I only see the traffic from Kamailio/RLS to the XCAP server to retrieve a resource-lists document, nothing about the rls-services document ?! Does RLS support rls-services ? If not what lists should contain the resource-lists document ? Cheers Pascal

[Kamailio-Users] DTMF and Kamailio
by Simon Muyal 20 May '09

20 May '09

Hello, I have the following topology: IPphones <-> IPBX-1 <-> <-> IPBX-A <-> IPphones IPphones <-> IPBX-2 <-> KAMAILIO <-> IPBX-B <-> IPphones ... IPphones <-> IPBX-N <-> IPBX-X <-> IPphones version: kamailio 1.4.1-notls (i386/linux) I experienced problems regarding DTMF digits transport. DTMF is transported through RTP data and it is not recognized at the end. Does anyone could recommend me how to force the negotiation between Kamailio and IPBXs to be sure that IPphones and IPBXs will use another method to transport DTMF (like OOB SIP INFO or RFC2833) Many thanks, Simon -- -------------------------------------------------------------- Simon Muyal Suivi des Services aux Usagers (SSU) Services operations & support Réseau National de Télécommunications pour la Technologie, l'Enseignement et la Recherche Tel: +33 (0) 1 53 94 20 40 | GIP RENATER Fax: +33 (0) 1 53 94 20 41 | c/o ENSAM E-mail: muyal(a)renater.fr | 151 Boulevard de l'Hôpital http://www.renater.fr | 75013 PARIS --------------------------------------------------------------

[Kamailio-Users] Load Based Load Balancing
by Kareem Hamdy 20 May '09

20 May '09

Hello: I've been going through your lists and your documentation, and I'm unable to find how you set up load based load balancing. To further illustrate: For example, let's say we have the following live calls:1,2,3,4,5,6,7 Round Robin Works Well ---------------------- +-----+ | SER | +-----+ | | +--------------+ |-------| FreeSWITCH 1 | [Calls 1,3,5,7] | +--------------+ | | +--------------+ |-------| FreeSWITCH 2 | [Calls 2,4,6] +--------------+ But let's say some of the calls end significantly quicker than the others, how can I send calls by their load (current calls, cpu, etc) For example, let's say we have the following live calls:1,2,3,4,5,6,7 - Let's say calls 4 and 5 lasted about 30 seconds, while the others lasted about 5 minutes. How would I be able to route calls to the box that's least used - in this example, "FreeSWITCH 2" at any given time had the least number of calls, so calls 4,5, and 6 were dispatched to it. Load Based Load Balancing ------------------------- +-----+ | SER | +-----+ | | +--------------+ |-------| FreeSWITCH 1 | [Calls 1,3,7] | +--------------+ | | +--------------+ |-------| FreeSWITCH 2 | [Calls 2,6] +--------------+ Thanks, Kareem
