Can't connect to db
by Andrew Chen 10 Sep '19

10 Sep '19

Hi all, I just installed kamailio 5.2.4 on two separate aws instances in two separate regions. Both regions uses the same configuration template and share the same db in AWS RDS. The issue I see is this: - SJO location was able to launch fine without any issues. - ASH location could not start up kamailio process due to db connection failure: Sep 10 21:24:13 ashmainkama51 /usr/sbin/kamailio[8043]: ERROR: db_mysql [km_my_con.c:139]: db_mysql_new_connection(): driver error: Too many connections Sep 10 21:24:13 ashmainkama51 /usr/sbin/kamailio[8043]: ERROR: <core> [db.c:319]: db_do_init2(): could not add connection to the pool Sep 10 21:24:13 ashmainkama51 /usr/sbin/kamailio[8045]: ERROR: db_mysql [km_my_con.c:139]: db_mysql_new_connection(): driver error: Too many connections Sep 10 21:24:13 ashmainkama51 /usr/sbin/kamailio[8045]: ERROR: <core> [db.c:319]: db_do_init2(): could not add connection to the pool Sep 10 21:24:13 ashmainkama51 /usr/sbin/kamailio[8045]: ERROR: carrierroute [db_carrierroute.c:141]: carrierroute_db_open(): can't connect to database. Sep 10 21:24:13 ashmainkama51 /usr/sbin/kamailio[8045]: ERROR: <core> [core/sr_module.c:847]: init_mod_child(): error while initializing module carrierroute (/usr/lib/x86_64-linux-gnu/kamailio/modules/carrierroute.so) (idx: 30 rank: 18 desc: [tcp receiver (generic) child=9]) - In ASH instance, I can manually mysql to the RDS host using the credentials in the config file. - I checked db user permissions and it's opened for the subnet in our ASH location (which is also proven using manual connection). So I don't get why one works and the other doesn't Thoughts? -- Andy Chen Sr. Telephony Lead Engineer -- *Confidentiality Notice: The information contained in this e-mail and any attachments may be confidential.

LCR lcr_id short or int?
by Grant Bagdasarian 10 Sep '19

10 Sep '19

Hello, The database tables definition for 5.2.x mentions the lcr_id parameter being of unsigned short type, while in the code I only see definitions of type int. Is it safe to assume the parameter is of type int, so the database column can also be set to an integer type? Regards, Grant

Share variable into reply route.
by Zhan Bazarov 09 Sep '19

09 Sep '19

Hello, we ran into a trouble with sharing variable into reply route... We are going to match asterisk's uniqueid with rtpengine records like this: route[from_asterisk]{ $var(UniqueId)=$hdr(X-UniqueId); $var(rtp_flags) = $var(rtp_flags) + " label={uid:$var(UniqueId),stream:outgoing} record-call=on"; rtpengine_manage($var(rtp_flags)); } reply_route[from_pstn]{ rtpengine_manage("replace-origin replace-session-connection ICE=remove RTP/AVP rtcp-mux-demux label={uid:$var(UniqueId),stream:outgoing"); } and it doesn't work... The one possible way what we found its using $shv instead of $var... But its unsecure way, cuz it may confus our bussines logic... Do you have any idea how to implement this? Many thanks!

Error Users - 604 Does not exist anywhere - HSS User Unknown
by Jack R 08 Sep '19

08 Sep '19

Hi, We have installed Kamailio as IMS setup pcscf icscf scscf - 3 instances running on Ubuntu.. 1. 2 Sip client registers successfully (shows Online) as 'bob(a)net1.test' and 'alice(a)net1.test' 2. When we check server logs: Invite request shows 'bob@IP address' i.e. ' bob(a)10.0.0.10' 3. However, in HSS it is registered as 'bob(a)net1.test'. 4. When the request from SCSCF goes to ISCSF it gives Error: Users - 604 Does not exist anywhere - HSS User Unknown. As it compares 'bob(a)10.0.0.10' with 'bob(a)net1.test'. Please help and advise how everywhere (SCSCF, PCSCF) during query/comparisons it can take 'bob(a)net1.test' and not 'bob(a)10.0.0.10' Thanks and Regards, Jack.

Kamailio - PfSense Firewall - inbound/outbound rules
by Youssef Boujraf 06 Sep '19

06 Sep '19

Dear All, I am evaluating the kamailio proxy 5.2 server with rtpproxy on an internal network. Everything are ok. Now, I would like to evalute Kamailio proxy from outside (internet) but I have some difficulties to setup my PfSense firewall to enable inbound & outbound rules, network settings and kamailio.cfg. The issues are : Setup correctly Network files : * /etc/hostname 127.0.0.1 localhost ip_private codecsip.mydomain codecsip ip_public codecsip.mydomain codecsip * /etc/hosts file codesip * dns * /etc/resolv.conf nameserver 8.8.8.8Setup /etc/kamailio/kamailio.cfg :#!define WITH_MYSQL #!define WITH_AUTH #!define WITH_USRLOCDB #!define WITH_NAT #!define WITH_TLS /* uncomment the next line to disable the auto discovery of local aliases based on reverse DNS on IPs (default on) */ #auto_aliases=no /* add local domain aliases */ alias="codecsip.mydomain" #!ifdef WITH_NAT # ----- rtpproxy params ----- # modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722") modparam("rtpproxy", "rtpproxy_sock", "unix:/var/run/rtpproxy/rtpproxy.sock") Setup etc/default/rtpproxy : CONTROL_SOCK=udp:127.0.0.1:7722 EXTRA_OPTS="-l <IP-address>" Where <IP-address> is the external IP address of your host. Regarding the firewall rules, it will be great to identify which rules I need to create : Inbound and outbound rules and NAT 1:1 ? If anyone have any information it could be great Best regards, Youssef

Kamailio HA
by Christian Attanasio 06 Sep '19

06 Sep '19

Hi everyone I use kamailio 5.1 with rtpengine and I would like to set up a simple warm standby or hot standby system for my sip server. on the web I found various discussions and posts that led me to deepen them the dispatcher, dmq, dmq_usrloc, db_cluster and p_usrloc modules. now, though, I'm a little confused: what approach do you recommend for this system? I thought of using two identical servers: Kam01 10.10.10.2 Kam02 10.10.10.3 Hostname cluster.mydomain.com each with its own mariadb and implementing data replication (with the dmq module? Or db_cluster and sqlops?). in this scenario is it necessary to also use the dispatcher module or implement a high available system with keepalives and floating ip? thanks, Christian

Kamalio & Asterisk integration erroneous behavior, setup issue
by Aristeidis Tsitras 05 Sep '19

05 Sep '19

new to the area and trying to setup Kamailio with Asterisk in a single machine. All users will register to Kamailio's port and in case of need for media, it will be forwarded to Asterisk, that is my intention. All of my work is based on the following link https://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb. Here is what i have done: - Debian 8, 64 bit machine with mysql and odbc - *root@kamast: ~ $ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 8.11 (jessie) Release: 8.11 Codename: jessie root@kamast: ~ $ uname -a Linux kamast 3.16.0-10-amd64 #1 SMP Debian 3.16.72-1 (2019-08-13) x86_64 GNU/Linux root@kamast: ~ $ * - Kamailio 5.2 installed from Kamailio's deb repository - Asterisk 13LTS installed from source - Used the same passwords such as kamailiorw and asterisk_password, since this is a test system, for proof of concept. I did import to the mysql>asterisk database 3 users 2200, 2201 and 2202. Then created in sip.conf the same 3 users with the same credentials. Then on 3 PCs i used softphones (Jitsi, Zoiper) and registered each account to a softphone. Problems: - Cannot see the users in the Asterisk's cli, sip show peers - I can see users only in Kamailio with kamctl ul show - A call between the extensions goes to voicemail. It never reaches the other destination eg 2200 calls 2201 and in Asterisk's console i am getting a message that 2201 is absent and it goes to voicemail. The same with any other extension. Attached you can find: 1. Kamailio.cfg 2. Asterisk's sip.conf 3. Asterisk's extension.conf 4. The import that i have done to mysql for the user creation. I would appreciate if someone could point me to the error and help me fix it please?

$Au being set to $fu instead of $fU
by Joel Serrano 05 Sep '19

05 Sep '19

Hi, Testing on latest master deb nightly build from last night I've noticed that when $au is not available, $Au is being set to $fu (uri) instead of $fU (username). Docs: https://www.kamailio.org/wiki/cookbooks/devel/pseudovariables ... $Au - Acc username: username for accounting purposes. It's a selective pseudo variable (inherited from acc module). It returns auth username ($au) if exists or From username ($fU) otherwise. ... I have the following log in several places in a test box: xlog("L_NOTICE", "[DEBUG] Au=$Au au=$au aU=$aU fU=$fU fu=$fu - \n"); And when I run through them (on both request and reply routes) I get the following: Aug 8 14:37:43 csbc01 csbc[9478]: NOTICE: {1 21564 REGISTER d8df9be1-1702e20b(a)A.B.C.D} <script>: [DEBUG] Au=1002366(a)some.domain au=<null> aU=<null> fU=1002366 fu=sip:1002366@some.domain - Aug 8 14:37:43 csbc01 csbc[9479]: NOTICE: {1 21565 REGISTER d8df9be1-1702e20b(a)A.B.C.D} <script>: [DEBUG] Au=1002366(a)some.domain au=1002366 aU=1002366 fU=1002366 fu=sip:1002366@some.domain - Aug 8 14:37:43 csbc01 csbc[9484]: NOTICE: {2 21565 REGISTER d8df9be1-1702e20b(a)A.B.C.D} <script>: [DEBUG] Au=1002366(a)some.domain au=<null> aU=<null> fU=1002366 fu=sip:1002366@some.domain - Those 3 logs belong to the same flow from different places in the config script. I would expect $Au to never have a "@some.domain" in it, so I assume in some place the replacement is not being done with $fU but with $fu. @Devs: I'm happy to create a GH issue for tracking etc if required, please let me know! Cheers, Joel.

How to detect miss call and accomplished call
by Anuran Barman 05 Sep '19

05 Sep '19

Hi, I want to show call logs in my SIP app. How can I do this with Kamailio? I want to do it from the *kamailio.cfg *file. Is it possible to do it from where? I guess Dialog module should be used for this, but can not figure out how to do it. I want minimalist feature like who call whom with timestamp, thats all. How can I do this?
