Send JSON document over http and process response
by Jonathan Hunter 22 Aug '16

22 Aug '16

Hi Guys, I need to send a JSON document over HTTP to a server, and then process the response, both in the kamailio configuration file. I assume I need to use Jansson module to extract contents of response? What is the best method for generating the initial request containing JSON ? Many thanks Jon

Howto timeout INVITEs over TCP to something < 30s?
by Daniel Tryba 22 Aug '16

22 Aug '16

If an enduser INVITEted over TCP t_set_fr(t) with t < 30s have no effect, the INVITE will always timeout after 30s. What is controlling this 30s? The only default at 30s is the fr_timer, which should have no part in the timeout between an 1xx and a final answer for an INVITE.

Evapi module is not broadcasting any data
by Efelin Novak 22 Aug '16

22 Aug '16

Hi folks, I came into a problem with evapi module, while I was trying to make the CGRateS tutorial work. It does not send any messages at all. Taken steps: I start kamailio with debug=3. I start: CGRates (on the kamailio machine) telnet 192.168.30.29 8448 (from my PC) tcpdump port 8448 -A -s0 -i any (on the kamailio machine) Telnet command successfully connects to kamailio. Kamailio yells: root@cgrates:/opt/kamailio/src/kamailio-4.4/kamailio# 11(12205) DEBUG: evapi [evapi_dispatch.c:453]: evapi_accept_client(): new connection - pos[1] from: [192.168.30.1:40312] 11(12205) INFO: <script>: Starting Evapi connector srcaddr 192.168.30.1 srcport 40312 condix 1 11(12205) DEBUG: htable [ht_var.c:90]: pv_set_ht_cell(): set value for $sht(cgrconn=>cgr) A similar message is printed when CGRateS connects in. Afterwards I make a call to Kamailio. INVITE is routed to a following command: evapi_async_relay("{\"event\":\"CGR_AUTH_REQUEST\", \"tr_index\":\"$T(id_index)\", \"tr_label\":\"$T(id_label)\", \"cgr_reqtype\":\"$dlg_var(cgrReqType)\", \"cgr_tenant\":\"$dlg_var(cgrTenant)\", \"cgr_account\":\"$dlg_var(cgrAccount)\", \"cgr_destination\":\"$dlg_var(cgrDestination)\", \"cgr_setuptime\":\"$TS\", \"cgr_computelcr\":\"true\"}"); Now the kamailio writes: . . . 2(12196) DEBUG: dialog [dlg_var.c:260]: print_lists(): Dialog var-list (0x7f196d1c5248): 2(12196) DEBUG: dialog [dlg_var.c:265]: print_lists(): cgrDestination=1002 (flags 1) 2(12196) DEBUG: dialog [dlg_var.c:265]: print_lists(): cgrAccount=1001 (flags 1) 2(12196) DEBUG: dialog [dlg_var.c:265]: print_lists(): cgrTenant= cgrates.org (flags 1) 2(12196) DEBUG: dialog [dlg_var.c:265]: print_lists(): cgrReqType=*prepaid (flags 1) 2(12196) DEBUG: dialog [dlg_hash.c:922]: dlg_unref(): unref dlg 0x7f196d1c4c08 with 1 -> 1 2(12196) DEBUG: evapi [evapi_dispatch.c:603]: evapi_relay(): relaying event data [{"event":"CGR_AUTH_REQUEST", "tr_index":"59559", "tr_label":"1886589610", "cgr_reqtype":"*prepaid", "cgr_tenant":"cgrates.org", "cgr_account":"1001", "cgr_destination":"1002", "cgr_setuptime":"1471623526", "cgr_computelcr":"true"}] (246) 2(12196) DEBUG: evapi [evapi_dispatch.c:628]: evapi_relay(): sending [0x7f196d1c88b8] [246:{"event":"CGR_AUTH_REQUEST", "tr_index":"59559", "tr_label":"1886589610", "cgr_reqtype":"*prepaid", "cgr_tenant":"cgrates.org", "cgr_account":"1001", "cgr_destination":"1002", "cgr_setuptime":"1471623526", "cgr_computelcr":"true"},] (251) 2(12196) DEBUG: evapi [evapi_dispatch.c:630]: evapi_relay(): Len of write is 8 2(12196) INFO: <script>: suspended transaction: 59559 / 1886589610 . . .

Contact header / bye
by Oliver Roth 19 Aug '16

19 Aug '16

Hi all I do have a problem with getting a propper interconnection to our new carrier.. Situation as following User --> Class5 switch --> Kamailio --> carrier I always get the ip of the class5 switch in the contact. But my carrier needs the kamailios contact ip - because of the ack handling. I replaced in the pstn routing parte the contact by remove_hf("Contact"); append_hf("Contact: <sip:xyz@a.b.c.d>\r\n"); This worked - but the bye did not work any more. Please help me on that topic ... I am searching for a solution for more than 8 weeks now ... KR, Oli

Running both 4.3 and 4.4 with the same database with permission module
by Daniel Tryba 19 Aug '16

19 Aug '16

I want to upgrade my cluster from 4.3 to 4.4, beginning with the spare for live testing. But since there is a change to the trusted table (which we don't use, only address) this isn't possible without some tricks. There is no override for skipping the version check on any permissions table. I need to share the subscriber/location/address/usr_preferences and db_aliases tables between the 4.3 and 4.4 machines. The only thing I can think of is: -patch the permissions module to accept the old version of trusted -create a 4.4 database and use federated tables to access the 4.3 data Not hard to implement any of these 2, but some other modules have the option to skip these checks, eg: http://www.kamailio.org/docs/modules/4.4.x/modules/auth_db.html#auth_db.p.v… Is there a reason not all modules have this flag (which you could use at your own risk)? Or am I missing something here?

Trouble with nat_uac_test()
by Noah Mehl 18 Aug '16

18 Aug '16

Hey all, I have a Kamailio implementation (version: kamailio 4.4.1 (x86_64/solaris) 12b048) as part of the Kazoo platform. I’m having an odd problem with an e2e ACK (after a 200OK after a T38 re-invite), which I’m pretty sure has to do with a Contact header rewrite due to the following (can review attached PCAP for specifics): if (nat_uac_test("3")) { force_rport(); fix_nated_contact(); } I have a couple of questions about this: A flag of 3, I don’t understand. I read the documentation <http://kamailio.org/docs/modules/4.4.x/modules/nathelper.html#nathelper.f.n…>, and there is a 1,2,4,8,etc… So, I’m guessing that a flag of 3, means 1+2? If #1 is true, then "the "received" test is used: address in the “Via” header is compared against source IP address of signaling” I don’t understand this test, as I’m pretty sure that the 200OK that’s getting re-written is properly constructed. I guess I’m trying to understand when one would want to use this test? Thanks! ~Noah

msilo route error
by Eng Hooda 18 Aug '16

18 Aug '16

Hello All, I am trying to enable msilo offline message delivery module, I used the official technical documentation : https://www.kamailio.org/docs/modules/stable/modules/msilo.html I managed to add load module statement and modparam statement without error. At this point msilo is still not active , it was obvious that I needed to add route statement. I copied the provided route statement , and edited it so will be similar to route functions that are already there. that was the outcome: # Routing to MSILO route[MSILO] { #!ifdef WITH_MSILO if ( !mf_process_maxfwd_header("10") ) { sl_send_reply("483","To Many Hops"); exit; }; if (uri==myself) { { # for testing purposes, simply okay all REGISTERs if (method=="REGISTER") { save("location"); log("REGISTER received -> dumping messages with MSILO\n"); # MSILO - dumping user's offline messages if (m_dump()) { log("MSILO: offline messages dumped - if they were\n"); }else{ log("MSILO: no offline messages dumped\n"); }; exit; }; # domestic SIP destinations are handled using our USRLOC DB if(!lookup("location")) { if (! t_newtran()) { sl_reply_error(); exit; }; # we do not care about anything else but MESSAGEs if (!method=="MESSAGE") { if (!t_reply("404", "Not found")) { sl_reply_error(); }; exit; }; log("MESSAGE received -> storing using MSILO\n"); # MSILO - storing as offline message if (m_store("$ru")) { log("MSILO: offline message stored\n"); if (!t_reply("202", "Accepted")) { sl_reply_error(); }; }else{ log("MSILO: offline message NOT stored\n"); if (!t_reply("503", "Service Unavailable")) { sl_reply_error(); }; }; exit; }; # if the downstream UA does not support MESSAGE requests # go to failure_route[1] t_on_failure("1"); t_relay(); exit; }; # forward anything else t_relay(); } failure_route[1] { # forwarding failed -- check if the request was a MESSAGE if (!method=="MESSAGE") { exit; }; log(1,"MSILO:the downstream UA doesn't support MESSAGEs\n"); # we have changed the R-URI with the contact address, ignore it now if (m_store("$ou")) { log("MSILO: offline message stored\n"); t_reply("202", "Accepted"); }else{ log("MSILO: offline message NOT stored\n"); t_reply("503", "Service Unavailable"); }; } #!endif return; } but after that I restarted kamailio service and got the following errors: root@debian:~# service kamailio restart Job for kamailio.service failed.
