Outbound flow failure handling merged to master
by Hugh Waite 23 Nov '16

23 Nov '16

Hello, As you will see I have merged my branch back into master. These changes add a new event route [tm:branch-failure] to the tm module which is run when any failure response is received on a transaction. The event_route uses a new route type BRANCH_ROUTE which limits the functions that can be run in the route. The functions t_check_status(), t_next_contact_flow(), t_relay() and unregister() can be used in this route. A new pv $T_reply_ruid is accessible in this route which can be used to unregister a single contact entry. The following example route can be used on a registrar to handle failed or invalid flows: event_route[tm:branch-failure] { xlog("L_INFO", "event_route[tm:branch-failure]\n"); if (t_check_status("430|403")) { if (!unregister("location", "$tu", "$T_reply_ruid")) { xlog("L_WARN", "failed to unregister $tu with ruid $T_reply_ruid\n"); } if (!t_next_contact_flow()) { xlog("L_INFO", "No more flows\n"); } else { xlog("L_INFO", "Next flow\n"); t_relay(); } } } Any bugs, memory leaks etc. let me know!

TM possible deadlock
by Jason Penton 09 Apr '15

09 Apr '15

Hi All, I have been experiencing a deadlock when a timeout occurs on a t_relayed() INVITE. Going through the code I have noticed a possible chance of deadlock (without re-entrant enabled). Here is my thinking: t_should_relay_response() is called with REPLY_LOCK when the timer process fires on the fr_inv_timer (no response from the INVITE that was relayed, other than 100 provisional) and a 408 is generated. However, from within that function there are calls to run_failure_handlers() which in turn *could* try and lock the reply (viz. somebody having a t_reply() call in the cfg file - in failure route block). This would result in another lock on the same transaction's REPLY_LOCK.... Has anybody else experienced something like this? this is on master btw. Cheers Jason

Fw: query related to NOTIFY message size

please help ----- Forwarded by Piyush Bansal/RCOM/RelianceADA on 10/10/2013 10:51 AM ----- From: Piyush Bansal/RCOM/RelianceADA To: serusers(a)iptel.org, serdev(a)iptel.org Date: 10/09/2013 12:14 PM Subject: query related to NOTIFY message size Hi there, I have certain queries regarding batch SUBSCRIBE and NOTIFY. I have a user who has 100 buddies in his buddy list. If any of his buddy changes his/her presence status, that user gets a NOTIFY message with presence status of all the 100 buddies. In that case, the message size is exceeding 500 KB. Thats quite a higher value for a UDP packet. Can anybody suggest- 1. If there is any way to restrict the size of the packet. 2. How to ensure that the packet is received correctly by the client.

RFC: updating default values
by Daniel-Constantin Mierla 02 Oct '14

02 Oct '14

Hello, I am opening this discussion to decide if there is need to adjust some of the default values we have in Kamailio. Many of them were set even like 10 years ago, so they might not be very actual anymore. The main goal is to get the best possible settings for common usage. To start with, here are some values that should be reviewed: - default private memory is 4MB - if the config is not that small, it might not be sufficient free pkg to play with (e.g., for sql_query() result, storage of $var(...) values). Should it be increased to 8MB or other value? Debian/Centos have startup script that sets its value to 8 via command line - default shared memory is 32MB - for a decent deployment with tm, location, lcr/dispatcher, permissions, and anti-flood, it might leave not much free space. Should we double it or set to a different value - usrloc - db_ops_ruid should enabled (1) - seems stable, without it there are problems updating/deleting location records when UA changes the call-id for same contact address. - usrloc - hash_size - now is 9, which results in 512 slots, meaning is ok for few thousands of registered users, for more, performance will decrease when doing save/lookup location -- should it be made 10 (1024 slots for internal hash table)? - auth_db - load_credentials defaults to 'rpid', meaning that the query to get the password will retrieve also the rpid column. I haven't see rpid being used that much lately (replaced by PAI/PPI). I would make this parameter empty by default to avoid querying for an extra column that is likely to be empty. Perhaps there are more, I just wanted to get started. Reply with your comments to above list as well as add new items you thinks their default values should be adjusted.

[PATCH 1/1] websocket: remove libunistring dependency

Using t_suspend()/t_continue() multiple times on the same transaction
by Peter Dunkley 02 Jul '14

02 Jul '14

Hi, I am trying to use t_suspend()/t_continue() multiple times on the same transaction. Calling t_suspend() more than once works, but the second time I call t_continue() the transaction is killed and a 500 response is sent. It is the "if (branch == t->nr_of_outgoings)" check from the code fragment below (from t_suspend.c:t_continue()) that results in the transaction being killed - you can see the debug/error line I added to determine this in the fragment. Is using t_suspend()/t_continue() multiple times something that should work? Thanks, Peter if (t->uas.status < 200) { /* No final reply has been sent yet. * Check whether or not there is any pending branch. */ for ( branch = 0; branch < t->nr_of_outgoings; branch++ ) { if ((t->uac[branch].request.buffer != NULL) && (t->uac[branch].last_received < 200) ) break; } if (branch == t->nr_of_outgoings) { /* There is not any open branch so there is * no chance that a final response will be received. */ ret = 0; LM_ERR("branch == t->nr_of_outgoings\n"); goto kill_trans; } } -- Peter Dunkley Technical Director Crocodile RCS Ltd

Hello, Is it possible to reload kamailio.cfg at the runtime after doing few modifications on the business rules laid under CNXCC module. Eg: #!ifdef CNXCC_CHANNEL xlog("L_INFO", "Setting up channel based credit control"); $var(max_chan) = 2; $var(retcode) = cnxcc_set_max_channels("$var(client)", "$var(max_chan)"); if ($var(retcode) == -1) { xlog("Error setting up credit control"); return; } $var(count) = -1; if (!cnxcc_get_channel_count("$var(client)", "$var(count)")) { xlog("Error getting customer's channel count"); } xlog("L_INFO", "CNXCC ROUTE: $var(client) has $var(count) call(s)"); if ($var(retcode) < -1) { xlog("Too many channels for customer"); sl_send_reply(403, "Forbidden"); if (!cnxcc_terminate_all("$var(client)")) { xlog("Error terminating customer's calls"); } exit; } #!endif ****************************************************** Now I want to change the value of max_chan on the fly. Does this step neccassitates a restart of kamailio process as a whole ? If no, then could somebody please guide me how to achieve this ? Thanks ! -- Warm Regds. MathuRahul

I** need to control many SIP Server IPs with limited channels to each with my** Kamailio Proxy.* *I am a newbie to kamailio world.* *-- Warm Regds.MathuRahul*
