decimal fraction problem

by 侯旭光

Hello I need to add q value while using function append_branch(),but the function only takes decimal fraction as the parameter. What if I want to use pv to add q value? The $var and $avp just have string and integer type. Thanks a lot!

OPENSER MIB

by Stefan Tiedje

Hi, In the Kamailio OPENSER-MIB there is the counter "openserTotalNumFailedDialogSetups". This is a Counter32. The description is: "The total number of calls that failed with an error. The following codes define a failed call:" Question: * I'm looking for the corresponding counter to "openserTotalNumFailedDialogSetups" who counts successful Dialog setups of Counter32 type. Does it exist? * If not, does it exist a work around? * Where in the code can the new suggested counter be added? * Something else???? Suggestion for the new counter is a name like: "openserTotalNumSucceededDialogSetups". It has a counter32. Description: "The total number of calls that succeeded" I know that there are the counters openserCurNumDialogs, openserCurNumDialogsInProgress and openserCurNumDialogsInSetup but these are of Gauge type who only reflects the current situation. These Gauge counters can't be used together with a Counter32 counter. That don't mix. The calculation done for the counter "openserCurNumDialogsInProgress" should be used where every new dialog setup is added to the new suggested counter. A counter of 32 should cover a great deal of connections. These counters are usually read, if used, every 15 minutes or 1 hour. Rationale: The reason for the new counter is that a calculation between succeeded and failed dialog setups can be done and be used for SLA agreements. Without this, its hard to make any customer versus provider agreements. /Stefan PS. Ask if anything is unclear and I need an answer rapidly.

acc failed_transaction_flag and t_newtran()

by Juha Heinanen

in order to get invite requests accounted, it seems that accounting flags need to be set before t_newtran() is called. is there any way to unset the accounting flags after calling t_newtran()? for example, i would not like to account invites that result to 407 proxy authentication required. -- juha

by Asgaroth

Hi All, I have a requirement to perform some processing based on the source and destination addresses on a message in on_reply route. I can get source ip address using $si pseudo variable, but I cant seem to access the destination ($dd). Is there any way I can access destination ip/domain of message in on_reply route? Thanks for any tips.

by Stefano Larosa

Hi, I'm new on Kamailio 3.0 This is the scenario I would like to build: 1 Subscriber A -> 2 kamailio -> 3 asterisk -> 4 Kamailio -> 5 Subscriber B Everything is working fine until the last step This is the code that manage the call from asterisk to kamailio if(is_method("INVITE") && (src_ip==80.169.xx.xx) ) { route(TOPROXYUSER); } And this is the code that should end the call the the subscriber route[TOPROXYUSER] { xlog("L_NOTICE", "$mi route[$rm][0] $fu -> $ru START PROCESSING MESSAGE\n"); rewritehostport("127.0.0.1:5060"); if (is_method("BYE|CANCEL")) { route(FAIL_ONE); } else if (is_method("INVITE")){ route(RELAY); }; exit; } Thank you, Stivu.

kamailio setup

by roman＠dmytriv.com

Hello there! I'm in the process of setting my first kamailio server and run into dead end. I was following your instructions very closely at http://www.kamailio.org/dokuwiki/doku.php/install:kamailio-3.1.x-from-git I'm using Centos 5.5 i386. Everything vent pretty much fine until step 7 were I had to create MySQL database. When I run /usr/local/kamailio-3.1/etc/kamailio/kamctlrc it gives me "Permission denied" error. I was able to access kamctlrc with a text editor and uncommented DBENGINE=MYSQL. Now when I run /usr/local/kamailio-3.1/sbin/kamdbctl create I have ERROR 2002. Please take a look at the attachment. Please help. Roman

Question about LCR

by Geoffrey Mina

Hello, I have a question about LCR which I have been unable to solve. I have 4 upstream carrier gateways owned by 2 carriers. Each carrier provides a primary and secondary gateway for load balancing purposes. On a 5XX error I am trying to send the same call to the other carrier. If both carriers reject the call with 5XX, I allow the response to go downstream to my asterisk server. The issue I am running into is that in a scenario where both my carriers respond with a 5XX, I end up presenting the same call to all 4 gateways. I would like to present the call to one gateway on each carrier and not try the same carriers second gateway for the same call. Here is what is happening now: ASTERISK --> INVITE --> KAMAILIO INVITE --> CARRIER A/GATEWAY 1 <-- 5XX Error INVITE --> CARRIER A/GATEWAY 2 <-- 5XX Error INVITE --> CARRIER B/GATEWAY 1 <-- 5XX Error INVITE --> CARRIER B/GATEWAY 2 <-- 5XX Error KAMAILIO --> 5XX Error --> ASTERISK OR any combination of the above... i.e. ASTERISK --> INVITE --> KAMAILIO INVITE --> CARRIER A/GATEWAY 1 <-- 5XX Error INVITE --> CARRIER B/GATEWAY 2 <-- 5XX Error INVITE --> CARRIER B/GATEWAY 1 <-- 5XX Error INVITE --> CARRIER A/GATEWAY 2 <-- 5XX Error KAMAILIO --> 5XX Error --> ASTERISK What I want to happen is: ASTERISK --> INVITE --> KAMAILIO INVITE --> CARRIER A/GATEWAY 1 or 2 <-- 5XX Error INVITE --> CARRIER B/GATEWAY 1 or 2 <-- 5XX Error KAMAILIO --> 5XX Error --> ASTERISK I tried dealing with the issue using some flags on the gateway, but i couldn't get the logic to work properly. Here is the path I was heading down, but my plan fell apart after some testing. CARRIER A has a gateway flag of "1" CARRIER B has a gateway flag of "2" failure_route[1]{ $var(gw_flag) = $avp(i:712); while(next_gw()){ if($var(gw_flag) != $avp(i:712)){ xlog("L_INFO","Found an LCR destination which is different than current, routing. ($ci)"); t_on_reply("1"); t_on_failure("1"); t_relay(); exit; }else{ xlog("L_INFO","The next destination in LCR has the same AVP flag, skipping. ($ci)"); } } # let the reply go upstram - it is the default action xlog("L_ERR", "No Next Gateway - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); exit; } Any help would be greatly appreciated. Thanks, Geoff

Does Kamailio support RFC5626 as Edge Proxy(or outbound proxy)

by Derrick Ding

Dear All, I wonder if Kamailio supports RFC5626 as edge proxy or outbound proxy. That is, Edge Proxy adds a Path header with a flow token and includes the "ob" parameter when Processing Register Requests. Eg: Path: <sip:VskztcQ/S8p4WPbOnHbuyh5iJvJIW3ib@ep1.example.com;lr;ob> If does, how can I config it in kamailio.cfg. At present, Kamailio can only forward register msg to sip server and reply 200 OK to SIP UA with "require: outbound" when register accepted. No "Path" and "ob" added in the msg forwarded to SIP server. You answer is appreciated!! Sincerely, Derrick
