Hi, First of all say that I'm new to Kamailio. I've been working with asterisk for a while now and it's time to get started with the sip router project. My idea for a start is to reduce the load of our asterisk servers and once we have good knowledge on how kamailio works, migrate some of our services. I've setup a server in our lab with kamailio 3.3.0 and siremis 3.3.0, created a user (subscriber) and registered with a softphone. So far OK. Now I'm trying to make a call and route it through one of our asterisk servers for testing. To do this I need LCR module (thanks Sébastien, I wasn't subscribed to this list yet) and configure it. After reading http://kamailio.org/docs/modules/stable/modules/lcr.html#id2553110 I've added in kamailio.cfg: #!define WITH_LCR #!ifdef WITH_LCR loadmodule "lcr.so" #!endif #!ifdef WITH_LCR # ----- lcr params ----- modparam("lcr", "db_url", DBURL) modparam("lcr", "gw_uri_avp", "$avp(i:709)") modparam("lcr", "ruri_user_avp", "$avp(i:500)") modparam("lcr", "tag_avp", "$avp(lcr_tag)") #!endif And now I see LCR module being loaded at startup. But, I don't understand what gw_uri_avp, ruri_user_avp or tag_avp mean. Where can I find some doc/manual to understand what AVP means and does? (For example the $avp(i:709), etc.) I've added a LCR GW, LCR TARGET and LCR RULE with the following data (I have no idea if it's completely wrong): mysql> select * from lcr_gw; +----+--------+---------+--------------+--------------------------+------+--------+------------+-----------+-------+--------+------+-------+---------+ | id | lcr_id | gw_name | ip_addr | hostname | port | params | uri_scheme | transport | strip | prefix | tag | flags | defunct | +----+--------+---------+--------------+--------------------------+------+--------+------------+-----------+-------+--------+------+-------+---------+ | 1 | 0 | TEST | XX.XXX.XXX.X | test12345678.testing.com | 5060 | NULL | 1 | 1 | NULL | NULL | NULL | 0 | NULL | +----+--------+---------+--------------+--------------------------+------+--------+------------+-----------+-------+--------+------+-------+---------+ 1 row in set (0.00 sec) mysql> select * from lcr_rule; +----+--------+--------+----------+-------------+---------+---------+ | id | lcr_id | prefix | from_uri | request_uri | stopper | enabled | +----+--------+--------+----------+-------------+---------+---------+ | 1 | 1 | .* | | | 0 | 1 | +----+--------+--------+----------+-------------+---------+---------+ 1 row in set (0.00 sec) mysql> select * from lcr_rule_target; +----+--------+---------+-------+----------+--------+ | id | lcr_id | rule_id | gw_id | priority | weight | +----+--------+---------+-------+----------+--------+ | 1 | 1 | 1 | 1 | 1 | 1 | +----+--------+---------+-------+----------+--------+ 1 row in set (0.00 sec) mysql> Am I still missing basic stuff to be able to place a call ? (To get started I'd like to route all calls to our Asterisk server) I'm glad to read documentation so If all of this is already somewhere please guide me cause I haven't found too much... Thanks in advanced. Regards, Joel.

Re: [SR-Users] RTPProxy with kamailio : How to get calls count?

by Alex Balashov

I'd be curious to know if your performance might actually be higher, owing to improved CPUs since the study was done, hyperthreading, more frames per NIC interrupt, etc. -- Alex -- Sent from my Samsung mobile, and thus lacking in the refinement one might expect from a proper keyboard.

dispatcher: What's "first destination" in a database

by Olle E. Johansson

Friends, Dispatcher has a mode 8 - "use first destination" which makes sense for a textfile driven dispatcher configuration. Now if I use a database - will dispatcher first sort on priority, then take the first? It seems so from the documentation of the text file: priority: sets the priority in destination list (based on it is done the initial ordering inside the set) Which one is top priority - lowest or highest value? I can update the docs to clarify if someone helps me with the answer :-) /O

Another NAT question

by Moacir Ferreira

Hi, I have a scenario where I got a firewall with 3 interfaces: internal, DMZ and external. All the traffic from internal going to external is NATed. However, the traffic between internal and DMZ is NOT NATed. The external and DMZ are using public IP addresses. On the DMZ I have a Kamailio server running with RTPProxy + NAT Helper. Everything works fine when public (from the internet) users (UAs) are behind NAT as Kamailio will force the RTP to go via RTPProxy. However, when the public user has a public IP, it will fail to establish the RTP to a user who registered on Kamailio coming from the internal firewall interface. The reason is that, as I don't do NAT between internal and DMZ firewall interfaces, Kamailio will not RTPRroxy in between the UAs because, from the way Kamailio detects NAT, they are not behind NAT. So the public user UA tries to reach a private IP address. If the "inside" user tries to call a public user (a user on the Internet with a public IP), it works. Yes, I could do NAT in between the internal and DMZ firewall interfaces. However, this would force all RTP traffic of my UAs at the LAN go to Kamailio RTPProxy, an bad effect that I would like to avoid. So my question is: what would be the best approach to solve this issue using Kamailio and RTPProxy in such scenario? Cheers! Moacir

siptrace buffer

by Martin Formanko

Hi, do you know what happens if the database for siptrace is not reachable ? I assume siptrace is non-blocking in new versions of kamailio, but is there any buffer? Or insert queries are discarded when timed out ? Mino

TLS Certificate Verification Issue

by Kamal Palei

Dear All I have modified kamailio,cfg and compiled all the modules with TLS enabled, and able to bring up the kamailio proxy properly. Kamailio proxy will receive the REGISTER message from endpoints in UDP , and want to send this REGISTER message to another intermediate proxy in TLS. For this purpose, I have added few lines in kamailio.cfg file as below. I have created the certificates, private keys as explained by README file in kamailio-3.1.5/modules/tls/ path. if(is_method("REGISTER")) { t_relay_to("tls:115.114.48.75:443"); exit(); } Looks like this is taking effect. When Kamailio receives REGISTER message it is trying to do handshake with intermediate proxy. I used wireshark to see the handshake messages. 1. From Kamailio proxy, a TCP SYNC message is going to intermediate proxy. 2. intermediate proxy sends SYNC + ACK 3. Kamailio sends CLIENT HELLO 4. intermediate proxy sends SERVER HELLO, CERTIFICATE and SERVER HELLO DONE 5. The Kamailio sends ALERT (Level: Fatal, Description: Unknown CA) ---> IS something going wrong here.............. 6. Then Kamailio sends FIN + ACK Can somebody please let me know why the certificate verification fails (I get this log in console). How can I put a work around to avoid certification verification failure. Best Regards kamal

Problem with my kamailio installation

by Ramazan Yilmaz

Hi, I installed kamailio 3.2.x a few times before and they were really fine. I decided to install a fresh one and followed the instructions on http://www.kamailio.org/wiki/install/3.3.x/git. However there is a problem: clients cannot register to kamailio. Each registration attempt produces the following error in the syslog: Oct 29 20:07:38 ubuntu /usr/local/kamailio-3.3/sbin/kamailio[32421]: : <core> [tcp_main.c:3578]: BUG: handle_ser_child: fd -1 for 0 (pid 32414) Oct 29 20:07:38 ubuntu /usr/local/kamailio-3.3/sbin/kamailio[32421]: : <core> [pass_fd.c:103]: ERROR: recv_all: 1st recv on 56 failed: Bad file descriptor Oct 29 20:07:38 ubuntu /usr/local/kamailio-3.3/sbin/kamailio[32421]: : <core> [tcp_main.c:3363]: ERROR: handle_tcp_child: read from tcp child 0 (pid 0, no 0) Bad file descriptor [9] Oct 29 20:07:38 ubuntu /usr/local/kamailio-3.3/sbin/kamailio[32421]: : <core> [pass_fd.c:209]: ERROR: send_fd: sendmsg failed sending 17 on 56: Bad file descriptor (9) Oct 29 20:07:38 ubuntu /usr/local/kamailio-3.3/sbin/kamailio[32421]: ERROR: <core> [tcp_main.c:4006]: ERROR: send2child: send_fd failed for 0x7f510bc41588 (flags 0x4018), fd 17 What could be the problem? Any suggestion? In case you need, the server is ubuntu server 11.10, and I installed including mysql and tls modules.

Entries in PUA List and RLS Watchers List

by Sangeeta Shah

Hello All, I am hoping the authors of the RLS/PUA modules can answer this question since I am not sure what's going on. I have the rls module enabled, with the following config spec: # ------rls module params ------ modparam("rls", "db_url", DBURL) modparam("rls", "db_mode", 2) modparam("rls", "integrated_xcap_server", 1) modparam("rls", "to_presence_code" ,10) modparam("rls", "server_address", "sip:rls@ip:5060") #!endif and modparam("pua_reginfo", "default_domain", "ip") modparam("pua_reginfo", "server_address", "sip:reginfo@ip") modparam("pua", "db_mode", 2) So for both I have DB_MODE set to DB ONLY. For whatever reason, even though all I am doing is bringing up my client I see over 250+ entries in the rls_watchers table for the same watcher and over 100 entries in the pua list table for the same presentity? Anyone have any idea what would be triggering this. There is definitely not anymore more than the normal messaging going on between the client and the server. Only error I see in the syslog: Oct 22 15:22:22 RCS-Presence /usr/local/sbin/kamailio[11745]: ERROR: db_mysql [km_dbase.c:122]: driver error on query: Duplicate entry '1350937406' for key 'expires_idx' Oct 22 15:22:22 RCS-Presence /usr/local/sbin/kamailio[11744]: DEBUG: presence [subscribe.c:1216]: subs->contact= sip:rls@ip:5060 - len = 25 Oct 22 15:22:22 RCS-Presence /usr/local/sbin/kamailio[11761]: DEBUG: <core> [db_val.c:117]: converting STRING [8475551001] Oct 22 15:22:22 RCS-Presence /usr/local/sbin/kamailio[11746]: DEBUG: <core> [parser/msg_parser.c:626]: method: <SUBSCRIBE> Oct 22 15:22:22 RCS-Presence /usr/local/sbin/kamailio[11745]: ERROR: <core> [db_query.c:210]: error while submitting query Oct 22 15:22:22 RCS-Presence /usr/local/sbin/kamailio[11744]: DEBUG: rls [rls.h:241]: did= 41826031568472f9-11752@127.0.0.1;533cb9e91f4b999cf76861cbb9ed54ed-93a3;a6a1c5f60faecf035a1ae5b6e96e979a-464d Oct 22 15:22:22 RCS-Presence /usr/local/sbin/kamailio[11761]: DEBUG: <core> [db_val.c:117]: converting STRING [10.50.251.12] Oct 22 15:22:22 RCS-Presence /usr/local/sbin/kamailio[11746]: DEBUG: <core> [parser/msg_parser.c:628]: uri: <sip:8475551001@ip> Oct 22 15:22:22 RCS-Presence /usr/local/sbin/kamailio[11745]: ERROR: pua [pua_db.c:1149]: DB insert failed -- Sangeeta Shah
