NAT Problem! Not relay ACK,CANCEL and BYE to other UA
by Nguyen Anh Tuan 10 Jan '13

10 Jan '13

Hi All, I have 2 interfaces - External A (behind NAT) and Internal B (LAN) in Kamailio Load Balance, and enable Multi-Homing function "mhomed=1". Load Balance dispatches to Kamailio SIP Servers via the Internal B (LAN) (each Kamailio SIP server has both proxy and registrar in one box). For RTP relay, I use RTPproxy in other server, has 2 interfaces A&B like Load Balance. If using 2 interfaces in Load Balance, Registration and calling NORMAL with 2 users behind NAT, but the call will be interrupted after 30 seconds due to the ACK message (after Ringing, 200 OK) STOP in Load Balance in return and not relayed to other UA . CANCEL and BYE have same error like ACK. I tried using only one interface for load balancing (External = Internal IP), and SIP Server binds to Load Balance in the same network, EVERYTHING IS OK. ACK, CANCEL and BYE are not missing behind NAT. For NAT Traversal I use PATH Module in Load Balance, and add "Received" like this: ... modparam("path", "use_received", 1) .. .. record_route(); add_path_received(); force_rport(); t_relay; .. .. And in SIP Server enable Path Parameter for Registrar: modparam("registrar", "use_path", 1) modparam("registrar", "path_mode", 1) modparam("registrar", "path_use_received", 1) Enable "#!define WITH_NAT" in default kamailio.cfg for RTP Controlling, but I removed all fix_nated_register and fix_nated_contact in SIP Server, because using PATH module.I try enable both fix_nat_register and fix_nated_contact, or only fix_nat_register but NOT SOLVE Problem "missing ACK,CANCEL, and BYE in Load Balance" behind NAT. Best Regard, Tuan.

Testing SIP Outbound / RFC5626 (Was: Freezing for next major release)
by Richard Brady 10 Jan '13

10 Jan '13

Hi Peter Great work on this! We'd like to help you test. The test I have in mind, which we could create using SIPp, would be to register multiple contacts with the same instance-id (i.e. "sip.instance" param) but different reg-id params. Then send an INVITE to that AoR and make sure the forking is only per instance-id and not per reg-id. This could be repeated in multiple permutations of instance-ids and reg-ids. This would be a test of save() and lookup() more than anything else. Is that what you had in mind?

LCR with Siremis
by Douglas Ugalde 09 Jan '13

09 Jan '13

Hi, I was configuring the modparams for LCR and Dialplan, I taken from kamailio web site, but I think the params are outdated, because we need to erase some lines to match with the tables in the DB, Im using Kamailio 3.3.3 and Siremis 3.3 Please can you give 1 example about how to make outbounds calls with siremis 3.3 (send calls to gateway)? I already have the lcr and dialplan module loaded with params. Where can I get update documentation about Siremis 3.3 and Kamailio 3.3.3. Thanks for your help.

Freezing development for v4.0.0
by Daniel-Constantin Mierla 09 Jan '13

09 Jan '13

Hello, a (26-hours before) reminder that development for next major release v4.0.0 will be frozen tomorrow, Thursday, January 10, 2013, at 23.59 GMT. If any developer has new features to push in the git master branch, please do it before. After that, for a while, the master should get only bug fixes and improvements to documentation and addition tools (e.g., bringing kamctl up to date). New features have to be kept in personal branches until the master branch is open again. The focus should be on testing from the day after tomorrow on, I hope the users community will help us here as well. Cheers, Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda

Re: [SR-Users] Having "modparam" options in the database

Hi Olle! The module we have been using, and wanted database configuration for was the pike module. But and after spending some more time looking at alternative modules, I see that we can use other modules to help us with traffic control/blocking, like the pipelimit and the ratelimit (both these modules have some sort of database integration, need to look more into this). I was so focused on the pike module, that I didn't see these other modules.. :) -- mvh Glenn O Larsen

Core fm_realloc function
by Bruno Bresciani 08 Jan '13

08 Jan '13

Hi all, I observed two at 0x08173bf0 in fm_realloc (qm=0xb5f7d000, p=0xb61f0bc0, size=0) at mem/f_malloc.c:536. I don't know exactly what may be caused this core because the debug of kamailio is disabled, but looking at backtrace (gdb) and source code I could notice a relationship with TLS connection establishment (handshake). Other important fact is that core was generated by the kamalio itself with signal 6 (abort) because it can't find the pointer to memory realloc. I'd like to know if someone already observed this issue and if my analyse above is correct? Bellow is backtrace full with gdb: Core was generated by `/home2/local/kamailio/sbin/kamailio -P /var/run/kamailio.pid'.

raw_query is crashing....
by Krishna Kurapati 08 Jan '13

08 Jan '13

Hi, Since there is no way to limit the result set to 1, I tried to use raw_query inside msilo module. Everytime it executes, it is crashing. The same query if I run in mysql shell, it is returning successfully. Here is the code That I added: query_len = snprintf(query, 2048, "SELECT * FROM %.*s WHERE %.*s='%.*s' AND %.*s='%.*s' AND %.*s!=%i AND %.*s<%i LIMIT 1;", ms_db_table.len, ms_db_table.s, sc_uri_touser.len, sc_uri_touser.s, puri.user.len, puri.user.s, sc_uri_tohost.len, sc_uri_tohost.s, puri.host.len, puri.host.s, sc_status.len, sc_status.s, 200, sc_status.len, sc_status.s, MSG_NOTIFY_OFFSET); if (query_len < 0) { LM_ERR("error in sql snprintf"); goto error; } LM_DBG("m_dump_msg: Query=%s\n", query); query_str.s = query; query_str.len = query_len; if (msilo_dbf.raw_query(db_con, &query_str, &db_res) < 0) { LM_ERR("Failed to query database.

LCR weight
by Ricardo Martinez 08 Jan '13

08 Jan '13

Hello. I have a doubt about the WEIGHT value in the LCR module. In the past we used the Kamailio version 1.5.2 and in that version LCR weight was calculated by a little script called lcr_weight_script.php. There was not “percent” values like 50% and 50% for two gateways despite that the probabilities were numbers calculated by the script. My question is : For Kamailio version 3.2.4 do I have to use the same script to calculate the weight?? I was almost sure that the weight column was a probability value. For example if I have 3 gateways, with 50% 25% and 25% The weight column should be : 50, 25 and 25 ? or 45, 32 and 32 as the script indicates??? [root@vlcr utils]# ./lcr_weight_test.sh 45 32 32 weight 45 probability 0.5235 weight 32 probability 0.2352 weight 32 probability 0.2413 Please enlighten me here. Thanks Ricardo.-
