Heads-up: testing needed for major OpenSSL refactoring
by Richard Chan 28 Jan '24

28 Jan '24

Hello Kamailio community, After the January refactoring of OpenSSL integration, configurations that initialise libssl in rank 0 (thread #1) are likely to trigger errors more aggressively. This type of configuration has all along been broken due to OpenSSL use of thread-local variables. The first "victim" is https://github.com/kamailio/kamailio/issues/3727 — the configuration has dispatcher + db_unixodbc (+ some driver) — this configuration initialises libssl in rank 0(thread #1). I have a couple of PRs in the queue for db_unixodbc, db_mysql (PostgreSQL may need similar attention). master and 5.7 branches are affected Regards Richard

LCR logic
by Social Boh 27 Jan '24

27 Jan '24

Hello, LCR module logic is : When the function /load_gws()/ is called, matching gateways (that are not currently designated as defunct) are ordered for forwarding purposes as follows: 1. according to longest Request-URI user part match 2. according to tuple's priority 3. according to tuple's randomized weight or, if priority_ordering parameter is set to value 1, as follows: 1. according to tuple's priority 2. according to tuple's randomized weight and Smaller priority value means higher priority (highest priority value being 0 and lowest being 255). so I have 3 lcr_rule_target use the same lcr_rule entry but 3 different Gateways and priority. So the order of rules would be longest Request-URI (same) and the priority but the result is: added matched_gws[0]=[3, 5, 200, 2193562] added matched_gws[1]=[1, 5, 2, 6888519] added matched_gws[2]=[2, 5, 50, 2159388] same prefix but first rule target with priority 200 and then 2 and then 50. I think the result would be priority 2,50 and 100. ¿Or not? --- I'm SoCIaL, MayBe

DMQ dialog sync question
by Stefan-Cristian Mititelu 26 Jan '24

26 Jan '24

Hi, I'm trying a DMQ dialog sync up setup with 2 x Kamailios. I have this scenario: 1. Kamailio1 receives INVITE and sends KDQM to Kamailio2 to sync up dialog => OK 2. Kamailio2 receives 200OK 3. Kamailio2 does not send anything back to Kamailio1 to update dialog state => not OK, i expected a KDMQ to be send back to Kamailio1 to update dialog state I was wondering if DMQ module supports the above? I am using 5.6 version of kamailio, and I am curios if this might be implemented in later branches? Thank you, Stefan

How to correctly drop a branch?
by Benoît Panizzon 26 Jan '24

26 Jan '24

Hi https://www.kamailio.org/wiki/cookbooks/devel/pseudovariables#branch_name_-… "Assigning $null to uri attribute will drop the branch, for the rest of attributes will just set the value to null." Where do I need to assing $null to the brach URI to get it dropped? And what happens to the index, is there a gap, or do the subsequent branches get re-indexed so they don't match with the ulc indexes anymore? Actual example, I have multiple contacts I would like to add to branches. Two of the contacts are from the location database + an additional contact. # Basic Branch: $ru = $(ulc(aor=>addr)[0]); $du = $(ulc(aor=>received)[0]); $fs = $(ulc(aor=>socket)[0]); # Additional Branch: append_branch($(ulc(aor=>addr)[1])); $(branch(dst_uri)[-1]) = $(ulc(aor=>received)[1]); $(branch(send_socket)[-1]) = $(ulc(aor=>socket)[1]); and so on, actually a loop over all ulc contacts. # Lasst Additional Branch, point to other registrar, not to a usrloc location. append_branch($ru); $(branch(dst_uri)[-1]) = "sip:other-registrar:5060;transport=udp"; $fsn = "LocalUDPv4"; $(branch(send_socket)[-1]) = $fs; t_on_branch("BR_T"); branch_route[BR_T] { $var(socket) = $(ulc(aor=>socket)[$T_branch_idx]); if ($var(socket) == 0) { xlog("L_INFO", "$cfg(route): DROPPING BRANCH: $T_branch_idx No local socket on this registrar\n"); $(branch(uri)[$T_branch_idx]) = $null; } } I don't get this right! Call is still sent to that contact. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

Change in LCR Debug
by Social Boh 26 Jan '24

26 Jan '24

Hello, using DEBUG with LCR module to see how the module apply the rules, I see he use Gateway Index in the list. The Gateway Index could be different to Gateway ID and maybe can confuse the correct interpretation about the use of the rules. Is it possible change the code: matched_gws[gw_index].gw_index = t->gw_index; matched_gws[gw_index].rule_id = rule->rule_id; matched_gws[gw_index].prefix_len = pl->prefix_len; matched_gws[gw_index].priority = t->priority; matched_gws[gw_index].weight = t->weight * (kam_rand() >> 8); matched_gws[gw_index].duplicate = 0; LM_DBG("added matched_gws[%d]=[%u %u, %u, %u, %u]\n", gw_index, t->gw_index, pl->prefix_len, t->priority, matched_gws[gw_index].weight); to use gateway ID and not gateway Index? Thank you Regards -- --- I'm SoCIaL, MayBe

412 Conditional request failed
by satyaprakash ch 26 Jan '24

26 Jan '24

Hi There were two PUBLISH requests were sent by the Kamailio Proxy server to the Kamailio Presence server. Processing of the first PUBLISH request resulted in the presentity table being updated - the "etag" changed from "a.1705053846.16611.21.1" to "a.1705053846.16613.23.2" Processing of the second PUBLISH failed because it also attempted to update the etag in the presentity table but at this point in time there was no match to the original etag value in the database Logs in kamailio.log: ------ ps_db_update_presentity(): No E-Tag match a.1705053846.16611.21.1 DEBUG: tm [t_reply.c:637]: _reply_light(): reply sent out - buf=0x7f81e5ca5fc0: SIP/2.0 412 Conditio... shmem=0x7f81de6da068: SIP/2.0 412 Conditional request failed. Will any one suggest how to resolve the issue of 412 conditional request failed.

How to assign xavp array to htable?
by Benoit Panizzon 26 Jan '24

26 Jan '24

Hi List Via sql_xquery I get a stacked xavp aka array. I would like to store that stacked xavp into a hash table for later usage in other transactions. Is this possible? Via xarp_parameters explode or implode does not work as that would stringy the same key multiple times.

How to set a branch specific variable?
by Benoit Panizzon 25 Jan '24

25 Jan '24

Hi Gang I would like to set a variable specific to the branch. Is there a way? append_branch($var(aor1)); $(branch(dst_uri)[-1]) = $var($dst1) $(branch(want_plus)[-1]) = 1; append_branch($var(aor2)); $(branch(dst_uri)[-1]) = $var($dst2) $(branch(want_plus)[-1]) = 0; t_on_branch("BR_T"); branch_route[BR_T] { if ($branch(want_plus)) { $rU = "+" + $rU; } } Or would there be a way to query the index of the added branch so I could stack an avp with that index to access in the branch route?
