by Federico San Martín 26 Aug '16

26 Aug '16

Hi guys, sorry for the newbie question, I searched for it and couldn't find any reference, is there a way to change the debug level of a kamailio server on the fly? If I need to add an additional module it's not a problem. I'm using version 4.4.2 on Debian Jessie. Thanks! Federico

Checking if a reply is part of a forked transaction
by Phil Lavin 25 Aug '16

25 Aug '16

We need to check if a 1XX reply is part of an INVITE transaction that was forked to 2 or more phones. We figure that we can do a location lookup, based on the to header of the 1XX... but is there a better way? Phil

Fwd: Kamailio with SNMP
by Rodrigo Moreira 24 Aug '16

24 Aug '16

Hello, Once set up and running the Kamailio environment would like to install SNMP and incorporate the functionality to collect the statistics of IMS entities. It's possible? When I call the module "snmpstats" I am informed that the module is not present. How can I solve? Another issue, which modules are monitorable via SNMP, P-CSCF, I-CSCF, S- CSCF? All? Regards. -- Rodrigo M. (37) 9132-4539 (34) 9889-3069 rodrigo.moreira2007

Monitor diameter state and number of current calls
by Ramiro Romero Arjona 23 Aug '16

23 Aug '16

Hi, We would like to know if there is some way to check the state of a diameter connection (to see is it's in state 6: connected), inside the kamailio configuration script. Also we would like to know if there is a way to see the number of current calls in a kamailio through kamcmd, kamctl or something like that. We have searched for a solution but we don't find anything. Many thanks.

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 . . . However no reply from CGRateS comes, tcpdump is quiet (no message was sent or received), as well as my testing telnet session (nothing is received).

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
