Google search

Hi guys, this happens to me all the time: when I search for documentation about a specific Kamailio module on Google, I always land on outdated entries usually from Kamailio 1.6.x. Although this seems trivial and I could simply update the URL to the current version of Kamailio, this may be not so obvious for new users and they may end up reading expired documentation and/or implementing non-optimal solutions to their problems. is there a way to only allow indexation of the last documentation? Something like removing the version or adding an HTTP 301 to old entries? Regards, -- Carlos http://caruizdiaz.com +595981146623

#cfgutils: sleep(x) does not work in failure_route
by Klaus Feichtinger 06 Nov '13

06 Nov '13

Hello list, I have troubles using the function "usleep(x)" or "sleep(x)" (the behaviour is the same) of the "cfgutils" module (http://kamailio.org/docs/modules/3.2.x/modules_k/cfgutils.html#idp76968) in the failure_route. According documentation, this function could be used in any route, including the failure_route, too. However, when I call this function, it does not show any reaction, if a transaction was already answered with a provisional response. It is still working fine, when a transaction is timing out, as no target socket is reachable. This is confusing me! Please find below some xlog messages from my configuration file in two scenarios (function "|t_set_fr(20000, 10000);" is identic in both scenarios|): (1) scenario 1 is including a primary target, looked up in the registrar DB, which is unreachable; after transaction timeout I have inserted the function "sleep()" in the failure_route for forcing a delay => here it is working fine (see timestamp) (2) scenario 2 is including a primary target which is responding, but not establishing the session; after transaction timeout the procedure is still the same as in scenario (1) => here is no delay visible in the log and practically detectable From my point of view, this is a malfuntion! Does anybody see it different? I´ve tested these scenarios with kamailio-3.2.x and kamailio-3.3.x - no difference. Thanks for any hints!

use append_hf() and remove_hf() on the same message
by Camille Oudot 06 Nov '13

06 Nov '13

Hi, I'm using remove_hf() and append_hf() to manipulate the sip headers on my application. Apparently, calling insert_hf("foo") after remove_hf("bar") if bar is the last header (not including Content-Length) is a bad idea, foo doesn't get inserted (I understand that the append_hf() command tries to insert foo after bar, and since bar just disappeared, well, it fails) What is the safest way to both remove and append headers on the same message? Regards -- Camille

dialog stats reported by app_perl
by mayamatakeshi 06 Nov '13

06 Nov '13

Hello, I am using kamailio 4.0. I am experimenting with module app_perl. Actually, I am not using it, I am just loading it because it solves this problem when loading snmpstats: /usr/lib/libnetsnmpagent.so.10: undefined symbol: boot_DynaLoader However, before using app_perl i was seeing this: # kamctl fifo get_statistics dialog active_dialogs dialog:active_dialogs = 1 But with app_perl loaded, I see this: # kamctl fifo get_statistics dialog active_dialogs app_perl:active_dialogs = 1 So, is app_perl intercepting stats requests that should be handled by module dialog? Is this expected? And, is there any performance penalty on having this handled by perl? Regards, Takeshi

TLS - No ServerHello
by Coy Cardwell 05 Nov '13

05 Nov '13

Hi all. We are using Kamailio 4.0.4 in an Edge Proxy to Central Registrar configuration. The system is in a functional state. Oddly, when we enable TLS, the Kamailio server never responds with a Server Hello to the Client Hello for TLS, so a connection is never established. Has anyone seen anything like this? There are no errors anywhere, the server just never responds to the initial TLS Client Hello. We know the packet arrives and is acknowledged at the TCP level. Just a bit stumped.
