[Kamailio-Users] Listening on more than one port
by Sven Schulz 12 Nov '09

12 Nov '09

Is it possible to have kamailio (1.4.4) to listen on more than one port? Is it as simple as adding another ³port=xxxx² in the config? Sven Schulz Penn State University Telecommunications and Network Services 814.865.6116 sip:sven@psu.edu

[Kamailio-Users] sending calls to voip provider
by Andres Moya 11 Nov '09

11 Nov '09

Hi, I am with openser about my first 40 hours. So far i managed to install 3.0. Was able to make calls between registered phones. Enabled accounting, etc. Looks i have control ;) Now i have a very simple question. I want to send calls for land lines via voip provider, sipdiscount.com in my case. I want to enable so registered client agent can send invite to that server, but it should re authenticate somehow. I was looking for proxy_authorize www_authorize but it looks like it authenticate my phones only. I was trying rewrite rewritehostport, but of course was getting authentications errors. Is there any manual, previous discussion on this topic? Thank you.

[Kamailio-Users] Problem in configuring LCR module
by Masoom Alam 11 Nov '09

Hi there, I am a first time user of Kamilio 1.5. We are trying to configure the LCR, we get an error in the syslog. The error in the syslog is: Nov 6 15:12:09 kam /sbin/kamailio[5396]: ERROR:lcr:mod_init: AVP fr_inv_timer_avp has not been defined Nov 6 15:12:09 kam /sbin/kamailio[5396]: ERROR:core:init_mod: failed to initialize module lcr Nov 6 15:12:09 kam /sbin/kamailio[5396]: ERROR:core:main: error while initializing modules We have already configured FR_inv_timer_avp parameter like this in the Kamilio.cfg: modparam("tm", "fr_inv_timer_avp", "$avp(i:70") The "tm" module is already loaded in the Kamilio.cfg. Please guide, where we are making problems?

[Kamailio-Users] Translate "486 Busy Here" to "600 Busy Everwhere"
by geoffreymina＠gmail.com 11 Nov '09

11 Nov '09

Hello, I have a need to translate a 486 from my asterisk server to a 600 when sending upstream to my carrier. The problem I am seeing is that when I return 486, the carrier re-presents the call to my next server in the SRV rotation... I really want the 486 to be a final disposition, so I am assuming sending a 600 would solve my issue. I am not sure how to go about forwarding the message, but modifying the SIP code... is that even allowed? This would be something like what I'm trying to do: failure_route[1]{ if(t_check_status("

[Kamailio-Users] Double acc records in DB
by Alex Hermann 10 Nov '09

10 Nov '09

Hello, I noticed that sometimes I get 2 identical acc records in the database, although I get only 1 in the syslog (I use both db_flag and log_flag). Of course, the second record in the DB shouldn't be there. There are no retransmissions of neither request nor response and only a single branch exists. How is this possible, and more importantly, how can I prevent the double records? This is on Kamailio 1.4+svn. -- Greetings, Alex Hermann

[Kamailio-Users] Question about translating 486 to 600
by Geoffrey Mina 10 Nov '09

10 Nov '09

Hello, I have a need to translate a 486 from my asterisk server into a 600 to my ITSP. I haven't figured out a way to force asterisk to send the 600, so I guess I need to rely on Kamailio to do that for me. The problem is that when the INVITE is sent to me, if I return a 486, my ITSP immediately sends a new INVITE to the next gateway in my SRV records. I want the 486 to be a final disposition in this scenario, so I am guessing I need to send 600 for the carrier to not try another gateway. How would I go about doing this? failure_route[1]{ if(t_check_status("486")){ t_relay("600","Busy Here"); } } I know the above example isn't valid... but that is basically what I need to accomplish. Thanks!

[Kamailio-Users] avp
by Anders 10 Nov '09

10 Nov '09

Hi all, Here I am - back with more "Kamailio 101"-questions! ;-) I need to strip the first character from the uri and write this to the 'acc' table. What I'm doing so far in kamailio.cfg is: modparam("acc", "db_extra", "............., $avp(s:user_ip_tag)"); So I've added the avp-thing in that line. And independently I've created a new column in the 'acc' table called "user_ip_tag". If the above is correct, my next step is to write something to this variable. In the routing, I have this: if (uri=~"^sip:[1-9]00*") { do_something_here_to_take_first_character_of_the_uri_and_put_to_avp...but_how? strip(1); } What I want to do, is to take the 1-9 digit, if it starts with that and has to zeroes after, and put that to the avp - and the strip it off before I move on in the routing. Yes, I have browsed the documentation, but I'm not sharp enough to understand it, it seems. (or alternatively, the documentation is not made for beginners). Thanks!
