no hangup when there is no network or when the UAC on the other side is power off
by Rabary 08 Mar '12

08 Mar '12

Hi everybody, We are using kamailio+callcontrol+cdrtool+freeradius+mysql to build a voip prepaid based system: . 2 SIP accounts created and one of them is prepaid . we can debit balance when we call with the SIP prepaid account, and when the balance is 0, the call hang up . if we hangup a call session from the prepaid SIP and the balance is not still 0, the call hangup and the system debit the appropriate cost . but when we call from the prepaid SIP account, and we disconnect the ethernet cable or the alimentation of the other UAC, the call don't hangup until the balance is set to 0 . if the phone is still ringing too, when we disconnect the other UAC, the caller UAC still ringing . the 2 uacs and kamailio are in the same subnet network the question is, how can we tell to kamailio to detect if the other side is down and then send bye immediately so thecalculating of the credit will be correct? Thank you. --

default IP to forward TCP request
by Laurent Schweizer 07 Mar '12

07 Mar '12

Hello all, I have a linux server with different IP. eth0 -> 10.2.2.4 eth0:1 -> 10.2.2.5 I have kamailio listening on IP: listen=udp:10.2.2.5:5060 listen=tcp:10.2.2.5:5060 and in the script I do : rewritehostport("10.2.2.10:5060;transport=tcp"); if (!t_relay()) { sl_reply_error(); } exit; the problem is that t_relay is not using the IP 10.2.2.5 to forward this SIP request but the eth0 IP ( 10.2.2.4) I see that they is a function force_send_socket , I need to use this function to set the correct IP used to forward the request ? As I'm using only one IP 10.2.2.5 for openser, why he cannot always use this ip as default Ip ? Best regards Laurent

Improving Kamailo configuration parser ...
by Krishna Kurapati 07 Mar '12

07 Mar '12

I used if ($var(x) != null) { ... } in one of the routes, and tried to run Kamailio server. The server exited with an error. I did not know why. Once I changed it to if ($var(x) != $null) {} the error went away. I missed $ infront null. I think it is hard to trace such problems once a large chunk of logic is written since many of us come from C++ and scripting background where $null is not a common practice. Also if I tried to use if (!$var(x)) { ... } Kamailio tries to convert the value of $var(x) to integer. prints WARNINGS in the log when the $var(x) consists of a string. Krish Kura

msilo is failing to in db connection...
by Krishna Kurapati 06 Mar '12

06 Mar '12

Hi all, I am trying to use msilo module from modules_k. Unfortunately it if failing during DB initialization. Other modules are initializing fine. I am using Kamailio 3.2.2. Not sure why the connection is not found. I tried to increase the MAX mysql connections to 250. I see the same error after I increase the connections. The config file is pretty standard: loadmodule "msilo.so" modparam("msilo", "add_date", 0); modparam("msilo", "db_url", DBURL); # The DBURL works for other modules... Here is the Log output: 0(14115) DEBUG: <core> [cfg.y:1684]: loading module msilo.so 0(14115) DEBUG: <core> [sr_module.c:557]: load_module: trying to load </usr/local/kamailio-3.2.2/lib64/kamailio/modules_k/msilo.so> ..... 0(14117) DEBUG: <core> [sr_module.c:928]: DEBUG: init_mod: msilo 0(14117) DEBUG: <core> [sr_module.c:667]: find_export_record: found <db_bind_api> in module db_mysql [/usr/local/kamailio-3.2.2/lib64/kamailio/modules/db_mysql.so] 0(14117) DEBUG: <core> [db.c:212]: using db bind api for db_mysql 0(14117) DEBUG: <core> [db.c:299]: connection 0x7fc20d1ace60 not found in pool 0(14117) DEBUG: db_mysql [km_my_con.c:94]: opening connection: mysql://xxxx:xxxx@localhost/openser 0(14117) ERROR: db_mysql [km_my_con.c:109]: driver error: Access denied for user 'openser'@'localhost' (using password: YES) 0(14117) ERROR: <core> [db.c:303]: could not add connection to the pool 0(14117) ERROR: msilo [msilo.c:319]: failed to connect to the database 0(14117) ERROR: <core> [sr_module.c:932]: init_mod(): Error while initializing module msilo (/usr/local/kamailio-3.2.2/lib64/kamailio/modules_k/msilo.so) ERROR: error while initializing modules Any help?

disptacher failover
by Klaus Darilion 06 Mar '12

06 Mar '12

Hi! Imagine a dispatcher list with 3 entries. I wonder what happens if one of the targets fail. Is the traffic moved evenly to the remaining 2 nodes or is the whole traffic of the broken node moved to one of the nodes? I took a quick look at the code and it seems that the whole traffic is moved to the next node in the list (i=i+1): while (ds_skip_dst(idx->dlist[i].flags)) { if(ds_use_default!=0 && idx->nr!=1) i = (i+1)%(idx->nr-1); else i = (i+1)%idx->nr; Is my assumption correct? Thanks Klaus

Question regarding... LCR Module
by kamailio Padawan 06 Mar '12

06 Mar '12

Hello, I have attempted to ask questions on IRC with no response. I really appreciate any help from anybody! I am using Kamailio 3.2.2. I am unable to get anything loaded in $avp(i:709). I am attempting to route between 2 media handling asterisk boxes. I am trying to load balance between them. I have the following entries in my tables... *lcr_gw* * id,lcr_id,gw_name,ip_addr,hostname,port,params,uri_scheme,transport,strip,prefix,tag,flags,defunct * 1, 1, media1, *1.1.3.123*, *1.1.3.123*, 5060, , 1, 1, 0, 0, 0 2, 1, media2, *1.1.4.123*, *1.1.4.123*, 5060, , 1, 1, 0, 0, 0 *lcr_rule* *id,lcr_id,prefix,from_uri,stopper,enabled* * * 1, 1, *[1][0-9][0-9][0-9][0-9]*, 0, 1 *lcr_rule_target* *id,lcr_id,rule_id,gw_id,priority,weight* 1, 1, 1, *1*, 1, 5 2, 1, 1, *2*, 1, 5 I was under the impression that, if my from URI was 15555, and I have 2 gateways, that I can call *load_gws("1","$fU")* and return the gateways that match the *from_uri* rule of 15555 , then look the rule_id up in * lcr_rule_target* and return the *2* gws gw_id[1] and gw_id[2], which are the 2 entries in the* lcr_gw* table..... and it would be weighted 5 and 5 so that it would load balance. Right now..... I get nothing loaded in $avp(i:709). I thought this would show the IP/Hostname of the media1 or media2 gws. The variable is null far before the call to *load_gws*. I'm loading it at the top in a modparam like *modparam("lcr", "gw_uri_avp", "$avp(i:709)")* *modparam("lcr", "ruri_user_avp", "$avp(i:500)")* When i get the result of calling the *load_gws*() function into a variable. The variable is *2*. Is that the number of rows returned? Why is that parameter [avp(i:709)] always empty? How can i get next_gw() to complete and not fail? Thank you so much.... I am very new to Kamailio and am very interested... Kamailio Padawan Learner
