You're right, it is application/sdp and the back slash works as escape character. However, a new problem came. I'm using this, since someone upstream is adding \r\n to a part of the body : replace_body_all("application\/sdp\r\n\r\n", "application/sdp\r\n"); The regex finds the application/sdp just right, but doesn't replace everything. So, as a final result i get applicationapplication\sdp\r\n. Is this intended? Thanks for your help

SIP Notify use UDP instead TCP

Hello, I'm trying to configure Kamailio 5.1 like "presence" server. Pretty much with default settings of kamailio: # ----- presence params ----- modparam("presence", "db_url", DBURL) ;modparam("presence", "server_address", "sip:10.0.6.226:5060" ) modparam("presence", "send_fast_notify", 0) modparam("presence", "db_update_period", 20) modparam("presence", "clean_period", 40) modparam("presence", "subs_db_mode", 2) modparam("presence", "fetch_rows", 1000) # ----- presence_xml params ----- modparam("presence_xml", "db_url", DBURL) modparam("presence_xml", "force_active", 1) # ----- presence_dialoginfo params ----- modparam("presence_dialoginfo", "force_single_dialog", 0) # ----- pua params ----- modparam("pua", "db_url", DBURL) modparam("pua", "db_mode", 2) modparam("pua", "update_period", 60) modparam("pua", "dlginfo_increase_version", 0) modparam("pua", "reginfo_increase_version", 0) modparam("pua", "check_remote_contact", 1) modparam("pua", "fetch_rows", 1000) # ----- pua_dialoginfo params ----- modparam("pua_dialoginfo", "include_callid", 1) modparam("pua_dialoginfo", "send_publish_flag", FLT_DLGINFO) modparam("pua_dialoginfo", "caller_confirmed", 0) modparam("pua_dialoginfo", "include_tags", 1) modparam("pua_dialoginfo", "override_lifetime", 124) # ----- dialog params ----- modparam("dialog", "db_url", DBURL) modparam("dialog", "enable_stats", 1) modparam("dialog", "db_mode", 1) modparam("dialog", "dlg_flag", FLT_DLG) And when UDP transport is using, everything works perfect. But when TCP is using (only "listen: tcp:IP:5060" is set) NOTIFY is not send. When "listen: tcp:IP:5060" and "listen: udp:IP:5060" I receive NOTIFY but through UDP.

Timer child process loosing MySQL connections
by Tobias Lindgren 19 Jun '18

19 Jun '18

Hi all! Having an issue with MySQL db connections being dropped in a system running 4.4.7. We're using db_mysql and db_cluster modules setup a cluster connecting two different DB servers. We have two cluster connections, one for acc and one for "other queries". One DB (A) is on the same network, another DB (B) is on another network. The default DB connection is for the remote server B. Auto reconnect is enabled. The specific issue seen is that the "timer" child process looses/drops both connections to DB A and B. Looking at the output from lsof when this happens, the connections usually does not both drop connections for A and B at the same time. Sometimes the connections keep up for ~24h, sometimes for 10 minutes, but normally the problem re-occurs every 6 hours or so. We're seeing this problem on two Kamailio servers, both handling fairly high amount of calls. None of the other Kamailio child processes seems to get their connections dropped, only the "timer" process. To solve this we need to restart Kamailio. Lately I've added the timer.so module to make a simple query on each cluster connection each 10 seconds. This is an example output from when the problem appears and connections are dropped: Jun 15 09:39:12 /usr/sbin/kamailio[10439]: ERROR: db_mysql [km_dbase.c:128]: db_mysql_submit_query(): driver error

Hi all, Few days back only, I started working on Kamailio IMS. I set up PSCSF, ICSCF, SCSCF and HSS(from open hss). When I try to send Register request from Zoiper, ICSCF is giving request timeout. At SCSCF, MAR failed error is logged. Kindly, let me know where I am doing wrong? >From my observation, At HSS, I can't see MAR request processing, It is only processing UAR from ICSCF. Find the attached log file. -- With Best Regards, Ashok Kumar.

TLS module and IPv6 (using tls.cfg).
by Joel Serrano 17 Jun '18

17 Jun '18

Hi all, I was playing around with the "config" modparam to specify and use a TLS configuration file instead of inline modparams inside kamailio.cfg. I did some testing and when I went to try with IPv6 I run into a little doubt?? tls.cfg config example: [server:1.2.3.4:5061] <----- How do you put an IPv6 in there? method = TLSv1 verify_certificate = yes require_certificate = no private_key = /usr/local/etc/kamailio/tls/local_key.pem certificate = /usr/local/etc/kamailio/tls/local_cert.pem verify_depth = 3 ca_list = local_ca.pem crl = local_crl.pem Applying the logic of the "listen" param, it should be: [server:[AAAA:BBBB:CCCC:DDDD:EEEE:FFFF:GGGG:HHHH]:5061] But it just seems totally wrong and I haven't found anything in the docs. Any suggestions? Thanks, Joel.

SDPC on SDP
by Duarte Rocha 17 Jun '18

17 Jun '18

Greetings, Please help me understand the reason and source of this behaviour on Kamailio. I receive a 200OK to a RE-INVITE that has : Session Name (s) : MySession Connection Information (c) : IN IP4 xxx.xxx.xxx.xxx Then, Kamailio routes the 200OK to it's destination, and it leaves Kamailio like this : Session Name (s) : MySession sdpc=IN xxx.xxx.xxx.xxx The line Connection Information got deleted and it's info is now on Session Name. How can i disable this ? Thanks

Alias listen
by kai.ohnacker＠cbc.de 17 Jun '18

17 Jun '18

Hello everybody, I have a question about the function "aliases". With my server no alias entry is registered and there is no DNS server (reverse DNS is not possible) in the network. Nevertheless, the SIP server listens to a defined alias. Is there next to the config file and the kamctlrc file another place where an alias can be entered? Cheers, Kai

Configuring Kamailio as a Proxy to another SIP trunk
by Ori Popowski 15 Jun '18

15 Jun '18

Hi, I'm making my first steps in Kamailio, and need help for a simple configuration. I am trying to configure Kamailio to forward SIP traffic from (and to) a SIP gateway to a Twilio SIP trunk: SIP gateway ----> Kamailio ----> Twilio SIP trunk How to configure Kamailio for this use case? How the kamailio.cfg file will look like in such case? Thanks.

add_uri_param with variables
by Patrick Wakano 15 Jun '18

15 Jun '18

Hello list, Hope you all doing well! We've been attempting to add a URI parameter to implement the trunk group (tgrp and trunk-context) but discovered the add_uri_param() function only works with constant string.... we can't use a pseudovar to inform the value to be added. Anyone knows why such limitation? Can it be changed? It is possible to do the same thing via the subst_uri function, but it would be so much more elegant to use the function... Thank you, Kind regards, Patrick Wakano

outbound flow tokens and kamailio restart
by Pan Christensen 14 Jun '18

14 Jun '18

Hello all. I have created a WebRTC to SIP gateway. I implemented it using the outbound module. If I restart Kamailio during a call, subsequent messages fail to be routed. {1 322 BYE 218565972_26748892(a)x.x.x.x} INFO: outbound [outbound_mod.c:261]: decode_flow_token(): flow-token failed validation {1 322 BYE 218565972_26748892(a)x.x.x.x} INFO: rr [loose.c:519]: process_outbound(): failed to decode flow token {1 322 BYE 218565972_26748892(a)x.x.x.x} INFO: rr [loose.c:794]: after_loose(): failed to process outbound flow-token Is it possible to make the flow token survive a restart?

Re: [SR-Users] Using a var as timeout value in dlg_set_timeout_by_profile function

Hello Jan, I just looked quickly in the code, it seems that the timeout value is not interpreted as "pseudo-variable", therefore its not possible to use something like $var in this method right now. It is just read as a numeric value. dialog.c, line 1342: if(dlg_set_timeout_by_profile((struct dlg_profile_table *) profile, &val_s, atoi(timeout_str)) != 0) This can of course changed in the module with a change in the code.

can't assign values to $fU
by Karthik Srinivasan 14 Jun '18

14 Jun '18

From the online documentation:$fU - From URI username *$fU* - reference to username in URI of 'From' header It is R/W variable (you can assign values to it directly in configuration file) But i am no able to assign values to $fU. Has anyone experienced this? Snippet of code in the configuration file of mine and its respective logs showing that $fU is not getting overwritten. I have tried to hard code values to it assign variables to it, all to no avail. configuration file code snippet: xlog("L_INFO", "[$ci] from header username pre mod: $fU"); $fU = "5555555555"; xlog("L_INFO", "[$ci] from header username post mod: $fU"); Logfile snippet: INFO: (s) [7EAB8FECD723E8444E36C659F331068B41EC6BB0] from header username pre mod: 3224567880 INFO: (s) [7EAB8FECD723E8444E36C659F331068B41EC6BB0] from header username post mod: 3224567880 Thanks, Karthik

Kamailio as outbound proxy for PBX
by Wilkins, Steve 14 Jun '18

14 Jun '18

Good Morning All! If a PBX(Asterisk) uses an outbound_proxy (such as Kamailio), can Kamailio actually make the SIP call? At some point I would like outbound calls to be controlled by Kamailio so that the outside endpoints never communicate with the PBX. Currently a call goes through Kamailio to Asterisk and then Asterisk communicates with the endpoint, and this is night ideal Thanks ALL

t_save_lumps() and failure_route
by Julien Chavanton 14 Jun '18

14 Jun '18

Hi, I have a scenario where I am using. t_save_lumps(), lookup() and then I can choose to drop some branches in branch routes. However, it is possible that I endup without any branch left, in this case t_relay() is returning and no failure route is called/created. At this point I need to recover the original message I believe it is not possible to restore/reset the message without passing by failure route ? Else, I could trigger a failure route using t_relay(), is there any "handy/clean" way to trigger failure_route() ? Regards

Memory leak in tm with push notifications
by Ivaylo Markov 14 Jun '18

14 Jun '18

Hello, I am trying to set up Kamailio as a push notifications proxy, closely following the example in the "Kamailio in a Mobile World" presentation (https://www.slideshare.net/FedericoCabiddu/kamailioinamobileworld-51617342). I am running Debian 9 and Kamailio 5.1.3 from the official Debian repositories. I believe the main modules involved in the issue below are tm, tmx, and tsilo. Every call passing through the proxy leads to a small memory leak in the tm module - there is a large amount of "delayed free" memory cells from tm's internal hash table. At some point the shared memory runs out and Kamailio restarts. Using the "kamcmd corex.shm_summary" command I was able to see that the top users of shared memory are "tm: h_table.c: build_cell" and "core: core/sip_msg_clone.c: sip_msg_shm_clone" with the same allocation count. I experimented with removing different parts of the configuration and noticed that commenting out the "t_continue(...)" call in the "PUSHJOIN" route (see slide #22) prevents the leak from happening. Maybe something in that function is incrementing the reference counter to the hash table cell, but it is not decrementing the counter when done? I tried looking around the source code of the tm and tmx modules, but saw nothing suspicious. I also tried using gdb with a breakpoint in t_continue_helper (tm/t_suspend.c:166) hoping to see what else is accessing the htable cell, but was unable to find anything of use. Has someone encountered anything like this? Can you provide more directions on debuggin this? I can provide some bits of configuration, but an entire test setup would be rather difficult, unfortunately. Thank you for your time, Ivo

Hello dears when i was trying to build an IMS platform by using kamailio with sip digest authentication scheme and ims_auth module, i couldn't register and the result was as following : 1-the first register message passed to the s-cscf then S-cscf replaying with the message “401 unauthorized - challenging the ue” 2- the second register pass to the S-cscf with the authorization header then the S-CSCF replying with "Forbidden - Private identity not found (Authorization: username)" So based on that could any one tell me what is the reason of this error and how to fix it ?? Thanks in advance

Using a var as timeout value in dlg_set_timeout_by_profile function
by jenus＠cyberchaos.nl 13 Jun '18

13 Jun '18

I'm trying to use the dlg_set_timeout_by_profile in the xhhtp route to update the dialog timeout for active calls. But if i use a var as the timeout value the call disconnects immediately. This works fine (call disconnects after 80 sec): dlg_set_timeout_by_profile("subscriber_outbound", "$var(SipName)@$var(SipDomain)::$var(DialogCallid)", "80"); This fails (call disconnects immediately: $var(DialogTimeout)= 80; dlg_set_timeout_by_profile("subscriber_outbound", "$var(SipName)@$var(SipDomain)::$var(DialogCallid)", "$var(DialogTimeout)"); Are vars supported in the dlg_set_timeout_by_profile function? And is it possible to use it in any route as described in the docs? I'm running kamailio 5.1.3. Thanks, Jan

Registration of UACs i n a partially encrypted scenario
by mip FKF 13 Jun '18

13 Jun '18

Hello, we are pretty new to SIP and kamailio, we do have some questions regarding the following scenario: We have a number of UACs in a small network which are required to communicate without encryption because the are not able to consume certificates. We want to use kamailio (as a proxy?) to establish an encrypted connection to a backend UAS. 1. Is it possible to directly register the UACs with the UAS eventhough communication between kamailio and the UAS is encrypted ? 2. How do we need to configure kamailio in order to make this scenario work ? Thank you for your suppport
