Question regarding t_check_trans()

by Joe Baran

Probably an elementary question, but we're relatively new at digging into the details. We are trying to understand the following block of config code and have a question or two. Our assumption is the t_precheck_trans() function tells us whether another packet has arrived already as a retransmission. However, we're not clear on what the t_check_trans() is doing assuming the condition is true. Any direction on this? Thanks. route[CHECK_RETRANS] { # handle retransmissions if(t_precheck_trans()) { t_check_trans(); exit; } } Joe Baran

Endpoints distribution to dispatcher

by Aidar Kamalov

Hello, I want to distribute endpoints calls in different cities to asterisks in the same cities where the endpoint. Now I use dispatcher for distibute calls beetwen asterisks, but without reference to the city. Can you please suggest better module and way for this? Is it better to distribute based on ip? Or may be based on groups? -- Aydar A. Kamalov

Fwd: Re: Fwd: kemi lua routing block as route in standart cfg

Cool!!! Thx for this reply and help. Yep i will need. I using WS.

If you use master branch (upcoming 5.1), modules having event routes export a parameter 'event_callback' which needs to be set to a name of a function inside the embedded language script, see the one for tm at: - https://kamailio.org/docs/modules/devel/modules/tm.html#tm.p .event_callback The dialog module should have same mod param. For websocket, do you need the one for xhttp module? If yes, it's available. The event_route[websocket:closed] is not available, as I can see in the code, but I will add it.

Pull Request or Issue? - coredump in case no contentLengthHdr present in REGISTER

by Valentin Christoph

Hi all, We have identified an IMS related issue, when the "Content-Length" header is missing in REGISTER request. It's a missing null pointer check in file modules/ims_auth/utils.c We are using Kamailio 4.4.5 for this purpose and we would need a fix in that release. I'm not sure, how to proceed now? Should I just create an "Issue" at GitHub, or is it possible for me to create a "Pull Request" at GitHub (would be less effort for you, I guess). Anyway, the change we did in our local GIT repository, is shown in following picture: [cid:image001.jpg@01D30C76.DE88AE10] Thanks, Christoph The information contained in this e-mail message is privileged and confidential and is for the exclusive use of the addressee.

Fwd: kemi lua routing block as route in standart cfg

by Yuriy Gorlichenko

thx. I just thought that it's possibe to concatenate both engines together. So this is my last question regardng kemi: Main goal why i still not use kemi at the my projects is a: TBD: the options for specific event_route blocks. Meanwhile, should work using hybrid configuration with request_route/reply_route/… in embedded interpreter and the other routing blocks in native kamailio.cfg. As i uderstand it is not possible to use event_route in a kemi. only native. If yes - do you expect t ointegrate this part of routes at the kemi interface in future? 2017-08-02 14:36 GMT+03:00 Daniel-Constantin Mierla <miconda(a)gmail.com>: > Hello, > > if you want to do routing in lua via kemi, the kamailio.cfg has only the > passive part (global parameters, loading modules and modparams) and the > active part (routing blocks) is a separate file written in the desired > scripting language (e.g., lua).

Sip-clients not connecting to kamailio, What am I missing?

by Viktor Silfver

Hi, I’m very new to Kamailio, in fact I have never got Kamailio to work properly. I’m following this tutorial http://kamailio.org/docs/tutorials/5.1.x/kamailio-install-guide-deb/ <http://kamailio.org/docs/tutorials/5.1.x/kamailio-install-guide-deb/> step by step, but my subscribers are not able to connect to Kamailio. (X-lite and Zoiper) I can install Kamialio, create the database, start Kamailio, add subscribers, without any failures or error messages. I’m running debian jessie. When i’m running wireshark I get the message Port unreachable. What am I missing? Can someone give me a hint on what I should look for?

route[LOCATION] is it bug?

by Aidar Kamalov

Hello, I 'm new in kamailio. I have kamailio with dispatcher and two asterisks. Endpoints register to kamailio. Calls beetwen endpoints going through dispatcher to asterisks. Calls to other destination rejected by kamailio with 404. But If i put xlog("AAAA") or xwarn in route[LOCATION] in if (!lookup("location")) block (default kamailio 5.0.2 config) calls to other destination goes through dispatcher to asterisks. I cant't understand WHY? :( (sorry for my bad English) route[LOCATION] { #!ifdef WITH_SPEEDDIAL # search for short dialing - 2-digit extension if($rU=~"^[0-9][0-9]$") { if(sd_lookup("speed_dial")) { route(SIPOUT); } } #!endif #!ifdef WITH_ALIASDB # search in DB-based aliases if(alias_db_lookup("dbaliases")) { route(SIPOUT); } #!endif $avp(oexten) = $rU; if (!lookup("location")) { xwarn("method ($rm) r-uri ($ru)\n"); ################## HERE ########################## $var(rc) = $rc; route(TOVOICEMAIL); t_newtran(); switch ($var(rc)) { case -1: case -3: send_reply("404", "Not Found"); exit; case -2: send_reply("405", "Method Not Allowed"); exit; } } # when routing via usrloc, log the missed calls also if (is_method("INVITE")) { setflag(FLT_ACCMISSED); } if(!ds_is_from_list()) { route(DISPATCH); } route(RELAY); exit; } -- Aydar A.

Kamailio inserting Quote " mark in SIP header

by Arslan Saeed

Hi All, We are seeing that Kamailio's nat_helper_module function of add_rcv_param(), inserts " (quote) mark to some of the SIP headers (as below in the contact header in sip 200 OK response) Contact: <sip:172.70.1.2:5060;bnc;received="sip:118.107.184.242:25090 ">;expires=172 We got few SIP UAs that are complaining about the quote mark inclusion in contact header and responding back with SIP 400 bad syntax status code. Requesting views / suggestions from community about this behavior of kamailio and any workarounds available. Cheers Arslan

Using a number as htable key name

by Jan Hazenberg

Hello, I'm trying to use a htable to reroute some numbers but when i'm trying to use kamcmd to add a entry where the element name is a number instead of a string i get a 500 error kamcmd htable.seti force_number 1234 1 error: 500 - Not enough parameters (htable name, key name and value) Also with quotes i get the 500 error: kamcmd htable.seti force_number "1234" 1 error: 500 - Not enough parameters (htable name, key name and value) But this works: kamcmd htable.seti force_number a1234 1 Is there a way to escape this so i can use a number as element name? Regards, Jan Hazenberg
