Variable $fu Kamailio 3.2
by Gilbert T. Gutierrez, Jr. 11 Apr '12

11 Apr '12

I wrote the code below to rewrite an extension to a phone number (It is called in route[LOCATION]). This code works fine with MULTIDOMAIN enabled but when I run it as a single domain the line $fu=$var(b); does not seem to work.. You can see that I have several xlog lines outputting the variable values into my /var/log/messages. $var(b) has the correct value in it, so I do not know what is happening. I have also included the /var/log/messages output which I redacted the phone number, domain, and extension for security purposes. I am sure I am going about this backwards, but can someone provide me some guidance as to what is going wrong? Thank you, Gilbert # Rewrite - Gilbert route[REWRITE] { # This section rewrites the outbound calling number so that caller id works correctly. #!ifdef WITH_REWRITE # lookup an outbound number to replace the extension with $var(b)="NO REV"; sql_xquery("ca","select number from pioutalias where username='$fU'","ra"); # determine if a outbound number exists if ($xavp(ra=>number)) { $var(b)="sip:" + $xavp(ra=>number) + "@" + $fd; xlog("L_INFO","var(b): '$var(b)'"); xlog("L_INFO","fu: '$fu'"); # Assign the outbound calling number $fu=$var(b); xlog("L_INFO","New fu: '$fu'"); } sql_result_free("ra"); # see if it found a number and log if it did not if ($var(b)=="NO REV") xlog("L_INFO","No number found for extension: '$fu'"); #!endif } /var/log/messages output Apr 9 14:38:38 tempfax /usr/sbin/kamailio[6088]: INFO: <script>: var(b): 'sip:602XXXXXXX@xxxx.com' Apr 9 14:38:38 tempfax /usr/sbin/kamailio[6088]: INFO: <script>: fu: 'sip:30XXXXX@xxxx.com' Apr 9 14:38:38 tempfax /usr/sbin/kamailio[6088]: INFO: <script>: New fu: 'sip:30XXXXX@xxxx.com'

dropped calls after 38 seconds openSER
by Saul Waizer 11 Apr '12

11 Apr '12

Greetings list, I am experiencing a strange behavior with openser 1.3.2 running on ubuntu 10. I have a basic configuration (see bellow) and i am using Linphone for iPad as my client. I have 2 users registered and I am able to place calls no problem. The problem is that the calls (audio or A/V) drop after 38 seconds exactly, this behavior is pretty consistent, 38 seconds is all I can get. There is no firewall in front of the clients. Here is my configuration, ip addresses changed to protect the innocent: http://pastie.org/private/x1ck8rxjcxv6hl44hrmqg You can see the logs of the call here (the majority): http://pastie.org/private/4fj5efpbsrxan8plzqvfza Am I missing something or is there anything that needs to be changed in the routing/configuration to achieve basic functionality? Thank you in advance!

[OT] sip:provider CE v2.5 is out!
by Andreas Granig 10 Apr '12

10 Apr '12

Hi all, I'm excited to announce the release of the Sipwise sip:provider Community Edition v2.5, a free and open source turn-key platform, which uses Kamailio, Sems and Asterisk in its core to provide a full-blown and feature-rich VoIP soft-switch. http://www.sipwise.com/news/announcements/spce-v2_5-release/ New core features are IPv6 and video support, serial call hunting and time based routing, beside lots of other fixes and enhancements. Check our VM images to get started within a couple of minutes and learn what can be built with the power of Kamailio as a stateless load-balancer and a stateful proxy/registrar, and Sems as an SBC and application server. Thanks a lot to all developers, contributors and members of this mailing list to make this possible and for helping us out! Andreas

Can rtpproxy be used withou NAT ?
by Rabary 10 Apr '12

10 Apr '12

Hi mailing, I installed kamailio 3.2, rtpproxy 1.2.1, callcontrol 2.0.15 on a vz, and cdrtool 8.2.5 and freeradius 2.1.10 on another vz. The 2 vz container have public ip address, and the UAC have private ip address. I want to use rtpproxy, and the following are what ps and netstat command returns about rtpproxy: teddy@kamailio:~$ ps aux | grep rtpproxy teddy 22866 0.0 0.0 3312 800 pts/0 S+ 11:08 0:00 grep rtpproxy teddy 31326 0.0 0.0 11360 804 ? Ssl Apr06 0:02 /usr/sbin/rtpproxy -F -l our_public_ip -s udp:localhost 22222 teddy@kamailio:~$ sudo netstat -pln | grep rtp udp 0 0 127.0.0.1:22222 0.0.0.0:* 31326/rtpproxy And my problem is: when I make calls, for example the UAC1 calls UAC2, with ngrep I see the UAC1 calls UAC1 and not UAC2, and I don't know why. In kamailio config file, there are directive WITH_NAT for everything related to rtpproxy (loadmodule, routing logic, etc) as you can see in the attached conf file. I try disable the use of this directive WITH_NAT so I disable the use of rtpproxy in kamailio and it works: when UAC1 calls UAC2, the UAC2 is ringing. Please tell me what am I doing wrong, or to use rtpproxy without NAT is not possible ? In attached file the kamailio config file, the diff between rtpproxy enable and rtpproxy disable, and the result of ngrep and what is in syslog when I made calls. Thanks in advance. -- Rabary Teddy Inutile d'imprimer ce mail

ACK to 200 OK discarded by loose_route()
by SIP Mailing-list 10 Apr '12

10 Apr '12

Hi guys, Hope someone can help me with this. The background: I'm just trying to implement a simple load balancer with one source and multiple destinations using the call load balancer (ALG10) in dispatcher. kamailio version 3.2.0 The symptoms: I have a simple script working in one test environment (csipsimple -> kamailaio -> Twinkle) but can't get it to work in another (Dialogic HMP 3.0 -> kamailio -> Dialogic HMP 3.0) The details: I've done a debug trace (below) in both environments and can't see the problem. For some reason the ACK is destroyed before it is forwarded even though the log says "[forward.c:601]: Sending:#012ACK..." Any help would be much appreciated!

SER or Kamailio
by Daniel Gonzalez 10 Apr '12

10 Apr '12

Hello, I am starting to deploy a SIP router, and after reading the documentation in http://sip-router.org I am a bit confused. I am planning to integrate the SIP router with an asterisk PBX. Which of the available projects is recommended to get in touch with the technology, SER or Kamailio? Which are most of you in the list using? Is there a particular use case where one or the other is more appropriate? Thanks, Daniel Gonzalez

Hello I need help concerning this issue , i am creating a testing scenario to make the RTPPROXY work , where i have a server having installed on it Asterisk , running on (192.168.10.15), and another pc connected to the Asterisk server having the ip (192.168.10.17) , on this same pc i've installed RTPPROXY and managed to insert another Ethernet card to connect to a client on ip (192.168.20.3) . After connecting any client on this ip 192.168.20.* , i manage to make a call i hear the ring but no audio conversation . My RTPPROXY command is : /usr/sbin/rtpproxy -F -s udp:192.168.10.17:22222 -l 192.168.20.3/192.168.10.17 -d DBUG:LOG_LOCAL0 Thank you
