cnxcc module
by Максим Панчоха 02 Oct '15

02 Oct '15

Hello! I'm trying to set max call duration, but after 5 seconds call is continues. Kamailio version: 4.3.2 Here's part of my config file: #!define CC_FLAG 29 ... modparam("cnxcc", "credit_check_period", 1) modparam("cnxcc", "redis", "addr=127.0.0.1;port=6379;db=1") modparam("dialog", "hash_size", 2048) modparam("dialog", "default_timeout", 3600) modparam("dialog", "db_mode", 0) modparam("dialog", "dlg_flag", DLG_FLAG) ... if ((is_method("INVITE")) && (is_request()) && (!has_totag())) { route(CNXCC); } route[CNXCC] { setflag(DLG_FLAG); if (!is_method("INVITE")) return; $var(client) = $fU; $var(max_time) = 5; if (!cnxcc_set_max_time("$var(client)", "$var(max_time)")) { xlog("Error setting up credit control"); return; } } event_route[dialog:failed] { xlog("L_INFO", "********END CALL*********$DLG_lifetime*******************"); } event_route[dialog:end] { xlog("L_INFO", "******END CALL************$DLG_lifetime****************"); } event_route[dialog:start] { xlog("L_INFO", "***********************DIALOG STARTED****************************"); } event_route[cnxcc:call-shutdown] { $var(duration) = $TS - $dlg(start_ts); xlog("L_INFO", *****END CALL***BALANCE IS EMPTY************$var(duration)*************"); } Tell me please, where I made a mistake. Thank you for a response.

blf problem
by huseyin kalyoncu 01 Oct '15

01 Oct '15

Hi I am trying to implement BLF functionality as described in http://kb.asipto.com/kamailio:presence:k43-blf. I am using the same conf with the one in the tutorial except that i am using postgres database instead of mysql. The problem is BLF is not working with this config (presence server and proxy server are in the same kamailio with same IP). But when I separate presence server from proxy server (2 different kamilio boxes with different IPs) BLF working perfect. i can see PUBLISH & NOTIFY messages in the tcpdump output with the working configuration. But i can not see any PUBLISH messages in the tcpdump output with the original config (one with presence and proxy servers are same). My question in the normal working environment (when BLF working perfectly); should i see PUBLISH and NOTIFY messages in the tcpdump output when the presence and proxy servers are the same? thanks Huseyin

SIP and conntrackd experience?
by Grant Bagdasarian 01 Oct '15

Hello, Does anyone have experience with SIP and conntrackd? Our media and signaling is separated. Does this work for VPN connections where SIP is sent over the VPN but the media over public internet? Thanks, Grant

modifying $fu / $fU (R-URI From)
by Sven Neuhaus 01 Oct '15

01 Oct '15

Hello, I'm having some troubles with modifying $fU in my kamailio.cfg. The following line appears to have no effect: $fU = $(fU{s.substr,2,0}); I would expect it to remove the first two leading characters from $fU. Has anyone else seen this? I have the same issue with modifying $fu. We're not using the uac module. And we're using the latest stable version of Kamailio. Thanks, -Sven

Crash kamailio 4.3.1
by Thibault Gueslin 30 Sep '15

30 Sep '15

After upgrading to kamailio 4.3.1 and modifying the config, I get this crash very often: ... CRITICAL: <core> [pass_fd.c:275]: receive_fd(): EOF on 21 ALERT: <core> [main.c:728]: handle_sigs(): child process 9341 exited by a signal 11 ALERT: <core> [main.c:731]: handle_sigs(): core was not generated INFO: <core> [main.c:743]: handle_sigs(): terminating due to SIGCHLD INFO: <core> [main.c:794]: sig_usr(): signal 15 received INFO: <core> [main.c:794]: sig_usr(): signal 15 received INFO: <core> [main.c:794]: sig_usr(): signal 15 received ... Is it known ? or may be related to my config ? Thank you Thibault

db_text and caching/reloading
by Asgaroth 30 Sep '15

30 Sep '15

Hi, I am busy testing the db_text module for some modules who's configuration does not change that often. If I set the db_mode for db_text to 0 (caching), it appears that if I modify the file directly (in this case the address dbtext file) and then issue a "kamctl address reload" the updated contents are *not* reloaded. However, if I set db_mode to 1, then the contents of the db_text file automatically reload when I change it on the file system. Is it possible to run db_text in caching mode but to also force a reload if I manually update the underlying database file? Additionally, in kamctlrc, I had to add the following variable: DBTEXT_PATH="/etc/kamailio/db_text" Whereas the original example for db_text path in kamctlrc is as follows: # database path used by dbtext, db_berkeley or sqlite #DB_PATH="/etc/kamailio/db_text" Is this just a typo in the kamctlrc distribution or is the variable meant to be DB_PATH or DBTEXT_PATH? Thanks

ACK and BYE are forwarded statelessly (failed to parse Route HF)
by Miroslav Dunaev 30 Sep '15

30 Sep '15

Hello everyone, I have a setup where kamailio acts as UAC to a SIP provider. Kamailio is also configured to pass all incoming calls to an Asterisk. Here is a diagram: Phone<-->Asterisk(10.10.11.232)<--->(PRIV:10.10.11.238)Kamailio(PUB:44.44.44.148)<--->(194.213.29.92)SIP-provider. When a call comes in from the SIP-provider, it gets all the way to the phone. But when the SIP-provider sends BYE or ACK (during hungup event or 200OK/SDP asterisk response.). I get this errors in my kamailio log: siputils [checks.c:100]: has_totag(): totag found <core> [parser/parse_rr.c:49]: do_parse_rr_body(): parse_rr_body(): No body for record-route rr [loose.c:106]: find_first_route(): failed to parse Route HF rr [loose.c:929]: loose_route(): There is no Route HF tm [t_lookup.c:648]: t_lookup_request(): DEBUG: t_lookup_request: no transaction found tm [t_lookup.c:1011]: t_check_msg(): DEBUG: t_check_msg: msg id=1 global id=0 T start=0xffffffffffffffff tm [t_lookup.c:466]: t_lookup_request(): t_lookup_request: start searching: hash=10101, isACK=1 tm [t_lookup.c:424]: matching_3261(): DEBUG: RFC3261 transaction matching failed ..... .... .... siputils [checks.c:100]: has_totag(): totag found tm [t_lookup.c:1312]: t_newtran(): DEBUG: t_newtran: msg id=2 , global msg id=1 , T on entrance=0xffffffffffffffff tm [t_lookup.c:466]: t_lookup_request(): t_lookup_request: start searching: hash=10101, isACK=1 tm [t_lookup.c:424]: matching_3261(): DEBUG: RFC3261 transaction matching failed tm [t_lookup.c:648]: t_lookup_request(): DEBUG: t_lookup_request: no transaction found tm [t_funcs.c:279]: t_relay_to(): SER: forwarding ACK statelessly here is the link to: kamailio.cfg, ngrep -i any capture, debug_level6 log: http://labmir.com/kamailio/ Looking at the SIP ACK that comes from SIP provider I can see that they use strict routing. (i.e. TO field is set to kamailio's public IP that is next hop to them). Maybe I am wrong to judge that its not loose routing just because of the TO field. Anyways, because of (failed to parse Route HF) error, ACKs and BYEs are forwarded by kamailio statelessly, as a result kamailio uses wrong interface to forward them (SIP_dailog.txt line:233) and therefore asterisk never sees ACKs or BYEs. How can I make kamailio recognize ACKs and BYEs belonging to a dialog and pass them statefully through the right interface? It is worth to mention that I use exactly the same config with a different SIP-provider (which is peered to our PUB IP not registered through UAC like in this case) and it works flawlessly. Thank you, Mir
