Fail Safe Environment for kamailio
by Owais ul Haq 12 Mar '14

12 Mar '14

Hello, Guys, I need some help. I am tasked to deploy "Fail Safe Architecture" for already running Kamailio Server in our organization. Presently one Kamailio Server is serving the cause with one internet connection and database on MySQL running on Windows 2008 Server R2(which is attached to kamailio server on other LAN card). Now the requirement is to deploy redundancy for internet connection and kamailio server. Like they want two kamailio servers running parallel, so if one fails, other will automatically take over and service will be available to users without any obstruction. At any cost, my organization want to absolutely minimize any possible blackout. To further elaborate my point. Here is the network we want. 2 incoming internet connections to 2 kamailio servers. Both attached to a single database placed at the backend. Now is it possible ?? If not what are constraints ?? What workaround is possible ?? I seriously need help as it is matter of job. Thanking in advance for help. P.S : kamailio server is running of Fedora machine in our environment. Cheers.

kamailio 4.1.X and ast 11.8
by lore 11 Mar '14

11 Mar '14

hello folks, i'm really new with kamailio (a couple fo days) and I need some suggestion/samples/idea/HELP to realize my environment. I've been starting to read the docs on website but there are a lot and i don't know where start and which kind of modules need to use I''d like to realize a trunk from kamailio and asterisk. Each one has their own sip users. kamailio sip users are some inside network and some outside network (behind nat) Could someone be son kind to show me the right way to configure kamailio for incoming/ougoing calls from/to asterisk and for using sip peers (behind nat and not)?. Also same samples are really preciated. Thanks a lot in advance Kind regards Lorenzo -- "Chi vive sperando muore cagando ...

how to get value of route param?
by Juha Heinanen 10 Mar '14

10 Mar '14

rr module has check_route_param(re) function that can be used to check if local route header has a param that matches re. however, there does not exist a function to find out what is the value of a given rr param. for example, if route header has param ;param=foo, how to extract value foo of param? there is @rr.uri.params select that together with {param.value,name} transformation might be able to do the job? -- juha

How to encode domain in username for Asterisk REGISTER forwarding (was: How to configure Kamailio + Asterisk (on same server) to route between several disjoint networks?)
by Alex Villacís Lasso 10 Mar '14

10 Mar '14

On the previous issue (disjoint networks), I eventually settled for binding Asterisk on localhost:5080, and using rtpproxy to route media to the networks as required. The only snag is that I had to write a script to rewrite the Kamailio configuration in order to take current IPs into account. Now, for the same project. What I want now is to be able to express multiple domains with an Asterisk backend. That is: given pbx.company1.com and pbx.company2.com, two DNS addresses that point to the same server, I want to have separate accounts bob(a)pbx.company1.com and bob(a)pbx.company2.com, with separate registration and accounting, without collisions. I know about the Kamailio "domain" module, and I have enabled WITH_MULTIDOMAIN and filled the kamailio.domain table for it to work. Now the authentication is taking domains into account. Next, I want to express two non-colliding registrations for Asterisk. What comes to mind is username rewrite - Kamailio sees bob(a)company1.com, and forwards a REGISTER to Asterisk using bob_company1_com as the SIP username. I am looking right now at the WITH_ASTERISK block that uses the uac module: # Forward REGISTER to Asterisk route[REGFWD] { if(!is_method("REGISTER")) { return; } $var(rip) = $sel(cfg_get.asterisk.bindip); $uac_req(method)="REGISTER"; $uac_req(ruri)="sip:" + $var(rip) + ":" + $sel(cfg_get.asterisk.bindport); $uac_req(furi)="sip:" + $au + "@" + $var(rip) + ":5060"; $uac_req(turi)="sip:" + $au + "@" + $var(rip) + ":5060"; $uac_req(hdrs)="Contact: <sip:" + $au + "@" + $sel(cfg_get.kamailio.bindip) + ":" + $sel(cfg_get.kamailio.bindport) + ">\r\n"; if($sel(contact.expires) != $null) $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $sel(contact.expires) + "\r\n"; else $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $hdr(Expires) + "\r\n"; uac_req_send(); } #!endif The above is the non-encoding version. What is the best way to modify it to do a domain encoding in the username? Or, if a better solution exists, what is it?

500 Forking capacity exceeded (12/SL)
by Camila Troncoso 07 Mar '14

07 Mar '14

Hi, I´m having problems with kamailio as LCR . I have a route with 14 different gateways, each one with priority 1 and all with the same weight. If one gateway is full, busy, down or answers with any failed response to LCR , I jump to the next gateway in the list. I´m presenting the problem that its stops jumping after 12 gateways and returns the message 500 Forking capacity exceeded (12/SL). I need to increase this limit , so all the gateways in the list give the call a try.

Hi folks, I'm new to Kamailio, and I am looking for some documentation on how to write config files, what should be included... etc.. I'm pretty much looking for product documentation and tutorials, not info on SIP (already went through the sip school). - How do I write a basic config file - Basic auth and forward examples I'm familiar with the cookbooks, however they don't really provide context as to what the recommendations do. Any resources that people could provide would be greatly appreciated. Thanks, Richard Seguin

Incorrect IP address in path header
by Rob Moore 06 Mar '14

06 Mar '14

Hi All, So an interesting one here. I'm doing pass through registrations using the dispatcher module in Kamailio and I'm using the Path Module to set the Path header In Register request so that Freeswitch knows to follow the route via Kamailio to find the sipPhone in future. In summary: [SIP Phone]------[NAT]------[(externalip)Kamailio(internalip)]-------[FS-Registrar] The problem I'm having is that the Path header is being added with the external ip address of the Kamailio instance not the internal ip e.g. "Path: sip:(externalip);transport=tcp" which mean FS doesn't root new calls out to the SIPPhone correctly via kamailios internal ip. I have noticed that if I remove the ;transport=tcp from the FS-Register address in my dispatcher group so that the last hop (from kamailio to FS-Register) is done over UDP then the problem corrects itself. (although this does present new issues whilst calling out back along the path from FS, and we also have a prerequisite to use TCP so this doesn't help). Has anyone had any experience of this issue? I can't see what I've done wrong here. Many Thanks Rob

dialog module with DB Backend
by jay binks 06 Mar '14

06 Mar '14

Hi all, im using the dialog module with db_cassandra backend.. I dont believe this issue is related to cassandra, but its worth mentioning anyways. so... I run kamailio, make calls, see dialogs in the DB.. and I Can use "kamctl mi dlg_list" and see that dialogs go away when I hangup a call.. When I query the DB Backend, I still see the queries, but they have a state of 5. I Initially thought this was a bug, but it seems dialogs in state 5 get cleaned up after a period. so I moved on. now , lets restart kamailio.. kamailio loads all dialogs on startup, after kamailio starts I call "kamctl mi dlg_list" again, and it shows all my dialogs from the DB. they DO show as "State 5" but for some reason, these dialogs appear to stick around for a long time, and the bigger issue it causes me is that my channel limiting ( using get_profile_size ) seems to consider these dialogs ( in state 5 ) as being active calls. Please someone point me in the right direction... :) what am I doing wrong ? ( or is this a bug somewhere ) Sincerely Jay

Hello, we are considering to release new versions from stable branches of Kamailio starting with Thursday, March 6. First is v4.1.2 from latest stable branch and if the time allows in the same day, the v4.0.6. The reason to release v3.3.7 is to have a proper debian packages built and hosted on the new repositories -- the specs had a conflict for latest 3.3 version of some sub-packages. If there are known issues that were not addressed, please report them to the tracker.
