Hi, I have followed instructions on setting up Kamailio with MongoDB backend, and successfully compiled and installed kamailio with the db_mongo module. It can start successfully. However, when I tried to add users using the command: kamctl add test testpasswd test(a)mysipserver.com <mailto:test@mysipserver.com> It fails because it is trying to default to MYSQL. Here is the result of that command: WARNING: database engine not found - tried 'MYSQL' ERROR: This command requires a database engine - none was loaded When I take a look at the kamctl script, it lists all the other kinds of database engines, except MongoDb, so this is probably why it is failing. How can I use kamctl to create the required Mongodb collections (like users, subscribers, etc) that Kamaiio will then use?My kamailio.cfg seem to be working ok, as I seem to be able to connect to the database (I modified the file to use db_mongo module), and I create the initial collections as listed here - https://www.kamailio.org/wiki/tutorials/kamailio-and-mongodb <https://www.kamailio.org/wiki/tutorials/kamailio-and-mongodb> Thanks, Chuks.

Regarding config-engines
by Alexander Rudenko 04 Jul '16

04 Jul '16

Hi, Question about future config-engines. Will it be possible to use connectors/drivers via the engine script and is it a good Idea? E.g. I have specific database and python driver for that database. May I use simple 'import dbdriver', create connection to the db, use it inside python engine script, etc? In general, in case there is no kamailio connector module for scpecific database, I would use python connector. Thanks in advance! -- *Alexander Rudenko*

re-Invite in the failure route
by Jay Li 04 Jul '16

04 Jul '16

Dear All, Hopefully I'll be able to get some help here on re-INVITE in the failure route. For example I have a couple of PSTN gateway options. I'd like to try them by priorities. In case the one with top priority couldn't go through(e.g. returned 5XX on INVITE), I'd like to re-INVITE through another provider in the failure route. Not sure what I should do for such cases. Thanks. Regards,Jay

Issue loading ims_dialog module
by Vikram Chhibber 01 Jul '16

Hi All, I am trying to bring-up PCSCF on releae 4.4 and I am getting errors related to loading of ims_dialog module. The mpath is set correctly in kamailio.cfg and ims_dialog.so is present in that path.

Distributed Authentication
by Colin Morelli 01 Jul '16

01 Jul '16

Hey all, I'm running a cluster of Kamailio instances as a proxy/registrar for another cluster of Freeswitch instances. I'm using http_async_client to make HTTP queries to my API to fetch credentials on auth challenges. Kamailio performs generating the header, and validating the result based on the data provided from my API. I'm fairly sure the answer is no, but I was wondering if Kamailio has any mechanism for getting access to the nonce/nc values in the challenges and responses so I can store them somewhere accessible to the whole cluster. Because my instances are transaction stateful, the request that is challenged and the subsequent request with the response may be routed to different instances and I want to validate the nonce correctly. I can move all of this into the API (the digest auth and verification), but my next question would be whether or not there are any APIs for getting access to this information in a structured format, or if I should just shove the whole digest auth header in the request to my API and parse/verify there. Thanks in advance. Best, Colin

Serialize Branches Based on q value
by John Petrini 01 Jul '16

01 Jul '16

Hello, I'm trying to append a branch, assign it a q value so it has priority and serialize the new branch and the main branch. The goal is to send the new branch off to our CNAM provider, capture the CNAM in their reply to a $var then drop the branch, stick the cnam in the main branch and allow the call to continue as normal. We do this currently using OpenSIPS and the serialize_branches(1) but the of load_contacts() seems to be different than serialize_branches. route[CNAM_DIPS] t_on_branch("CNAM_DIPS"); t_on_reply("CNAM_DIPS"); t_on_failure("CNAM_DIPS"); t_load_contacts(); t_next_contacts(); append_branch("sip:2223334444@22.33.444.55:5600;trans-type=5", "0.5"); relay(); break; Two problems. First when t_next_contacts is called I get the following error: ERROR: pv [pv_branch.c:58]: pv_get_branchx(): error accessing branch [0] Second problem is that my call goes out on the branch I appended and I get a reply from the CNAM provider but Kamailio forwards that reply back to the phone causing the phone to send a second invite. In OpenSIPs we just called drop, to drop the branch and let the main branch continue but this doesn't seem to work in Kamailio. I've read and reread the documentaion but it doesn't seem to behave the way the documentation says it should. Is there something I'm missing? Is there a better way to accomplish this in Kamailio? Thank You, ___ John Petrini

Dialplan module doubt
by José Seabra 01 Jul '16

01 Jul '16

Hello there, I'm evaluating if I can use dial-plan and dispatcher module to build a kamailio routing server to route calls based on number dialed(sometimes the number dialed can be Alphanumeric). I'm expecting have lot of dial-plan entries, some of them with manipulations, others without. Anyone can see here any limitation on this implementation? One thing that I have noticed is that dial-plan module enforces me to fill the fields substr_exp and repl_exp even if i don't have any manipulations to apply. I'm also concerning about performance issues with lot of dialplan entries. What are your thoughts about this solution? Thank you -- José Seabra

ACK / BYE transaction problem
by Oliver Roth 01 Jul '16

01 Jul '16

Hi all Follow scenario Class5 system [c5] --> Loadbalancer kamailio (dispatcher module) [lbl] ---> gateway kamailio [gw] --> carrier [carr] I get Invites from [c5] with Request ,To, from, contact, pid in national format 0794445566 [lbl] dispatches this to [gw] For the [carr] I need international format. So doing these transactions in [gw] And sending to [carr] in international format Request, to, from, contact, ... => 417794445566 Everything ok Then I get a 100, 183 and even 200 from [carr] Ack is coming from [c5] to [lbl] and [gw] - but then it stocks The ACK is not sent to the [carr] I kamailio log I see DEBUG: RFC3261 transaction matching failed DEBUG: t_lookup_request: no transaction found So for me, the ACK cannot be assigned to a transaction and gets discarded by if ( is_method("ACK") ) { xlog(,"L_INFO", "WITHINDLG ACK - not loose route\n"); if ( t_check_trans() ) { xlog(,"L_INFO", "WITHINDLG ACK - t_check_trans() \n"); # no loose-route, but stateful ACK; # must be an ACK after a 487 # or e.g. 404 from upstream server t_relay(); exit; } else { xlog(,"L_INFO", "WITHINDLG ACK - not t_check_trans() DISCARD!!\n"); # ACK without matching transaction ... ignore and discard route(NATMANAGE); #t_relay(); #exit; Any idea? Problem with modifying the sip tags? Or problem with the dialog? Thanks for helping OIi

Kamailio Iterate All Headers
by Colin Morelli 01 Jul '16

01 Jul '16

Hey all, Back with more questions. I'm using Kamailio to make an HTTP call to my API to perform authentication and message routing. Currently, I'm trying to build up the post body that I send to my API to make those decisions. I've cherry picked a few of the headers that are important in my routing decisions. But, ideally, I'd like to just iterate over all the SIP message headers and append them as request parameters to my API call. Is this possible with Kamailio? I've been looking through the docs and can't seem to find a function to iterate the full list of headers. Thanks in advance. Best, Colin

Get registered user list
by Никита Лебедев 01 Jul '16

01 Jul '16

Good day! Can anyone point me to right direction? The question is - I want to get list of registered users (to find out who is online at the moment) from sip server. I'm using kamailio on server side and exosip library on client side. I tried to find something in RFC 3261 and failured... Can someone help and tell what to do or where to look for the answer?
