Kamailio with Private IP - ACK for 200 OK problem
by Krishna Kurapati 26 Jan '12

26 Jan '12

Hi, I am having trouble with setting Record Route when Kamailio is behind a Load balancer. The Load balancer acts as a static NAT where the public IP of the load balancer is mapped to private IP of the Kamailio. This is creating issues with ACK for 200 OK since Kamailio is stuffing the 200 OK with private-ip in the Record-Route. The UAC looks like trying to send ACK back to this private IP which is not reachable. Is there a configuration option to let kamailio use Public IP when setting record-route in 200 OK? Thanks for any help... Krish Kura

Memory usage problem in xmpp modules
by laura testi 26 Jan '12

26 Jan '12

Hi, we are using the XMPP gateway modules: • PUA • PUA_XMPP • XMPP The behavior is ok but since the modules are started, the memory usage is getting increased and now also the swap memory area is used. I send to you the following information: 1. Numer of records from PUA and xmpp_presentity tables, they are quite stable: SQL> select count(*) from pua; COUNT(*) ---------- 10218 SQL> select count(*) from xmpp_presentity; COUNT(*) ---------- 754 2. list of PKG fragments with gdb : $1 = {size = 40, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $2 = {size = 32, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $3 = {size = 40, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $4 = {size = 40, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $5 = {size = 40, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $6 = {size = 104, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $7 = {size = 32, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $8 = {size = 32, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $9 = {size = 56, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $10 = {size = 96, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $11 = {size = 56, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $12 = {size = 112, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $13 = {size = 24, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $14 = {size = 24, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $15 = {size = 40, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $16 = {size = 40, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160} $17 = {size = 40, u = {nxt_free = 0x0, is_free = 0}, file = 0x2b657aa12c00 "presence: utils_func.h", func = 0x2b657aa1aed0 "uandd_to_uri", line = 66, check = 4042322160}…………. 3.

Call Control Behavior
by Reda Aouad 26 Jan '12

26 Jan '12

Hi, My question concerns Call Control. When a SIP call's timer ends, Call Control uses dlg_end_dlg MI command of the dialog module to send a BYE to the UA. Can I intercept the BYE message, drop it, change it and send instead an INVITE or a REDIRECT using (maybe) the UAC module? The INVITE/REDIRECT would connect the UA to a media gateway to announce a message when the session ends. Any ideas? This also leads to thoughts on accounting and rating. In the case of sending and INVITE, the rating of the call becomes inaccurate since there's no BYE when the call ends, but only after the media gateway's announcement ends. In the case of a REDIRECT, the UA sends a BYE to the established call before the INVITE to the media gateway, and thus rating remains totally accurate. What do you think? Thanks RA

Kamailio Redundancy examples/pointers required
by Sammy Govind 26 Jan '12

26 Jan '12

Hello list, I've been looking for ways to create a redundant Kamailio cluster. I've googled alot but haven't got any concrete or final wording on any one solution that'll just work perfectly. The basic requirement is that in case of Kamailio application failure or in case of physical machine error the whole setup just starts working on secondary server. Please suggest anything whichever you guys are using. Any reference URLs would be very much appreciated. Thanks and Regards, Sammy

access to the "Available Functions" in the modules & the way to bridge a call based on username and domain
by Xi Liu 25 Jan '12

25 Jan '12

Hi, I'm new to kamailio, have some questions here hope anyone can help! Question 1, I'm trying to use some of the functions in usrloc module, but for some reason if I use those from "Available Functions" part, the kamailio won't start and give an error of "unknown command <ul_get_ucontact>, missing loadmodule?" The usrloc module is definitely loaded, and it will start as long as I avoid using those "Available Functions". I tried some other modules it will lead to same error. Question 2, What is the simplest way to bridge a call based on username and domain? I was trying to make a simple experiment I used to do in Freeswitch, ========================== Have 1000,1001,1002 registered, When 1000 calls 9999, the calls will be bridged to 1001 or 1002 based on different time period. ========================== While in Freeswitch, it would be as simple as "bridge xxxx(a)domain.com", and then freeswitch will lookup contact information and forward the call. But in kamailio, I only succeed in forwarding calls by change the $du to the exact contact uri, which is "sip:xxxx@ip-of-the-phone:port", the call r_relay(). In order to do this, I need call a perl script to lookup the location database to find a match… I'm 99% sure I'm doing wrong here… there must be a way way easier than that, but so far I can't find it…. Please help… Thanks, Xi

Hello everyone, I'm new here and I go to test my settings, but I need to authenticate a remote server, I was reading about the UAC module, one has configuration examples?
