Dispatcher's Probing
by Duarte Rocha 26 Sep '18

26 Sep '18

Hey, I've been using the Dispatcher module with great results. But now, i want to be able to have some gateways to belong to more than one group set. To achieve that, i'm duplicating the Gateway in the Dispatcher's table and give it a different group set. However, if i do this, Dispatcher will do repeated probing to this gateways. Is there any way to avoid this or to achieve the same result in a different way? Best Regards

No dispatcher failover
by Gertjan Wolzak 26 Sep '18

26 Sep '18

Hello Kamailions, I want to send traffic to an Asterisk box but when that box fails traffic should be routed to the second Asterisk box. The dispatcher params are as follows: # ----- Dispatcher params ------ modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_ping_interval", 20) modparam("dispatcher", "ds_ping_reply_codes", "class=2;class=3;class=4") modparam("dispatcher", "ds_inactive_threshold", 4) modparam("dispatcher", "ds_ping_latency_stats", 1) modparam("dispatcher", "ds_probing_threshold", 1) My dispatcher.list is: #DBBS PBX # SBC's 1 sip:ip_address_sbc:5060 0 0 weight=100 #PBX 2 sip:ip_pbx_01:5060 0 10 weight=100 2 sip:ip_pbx_02:5060 0 5 weight=100 Verry simple request route: request_route { if (is_method("OPTIONS")) { sl_send_reply("200", "OK"); exit; } #Call from SBC to PBX #Get gateway from dispatcher list if($si=="ip_address_sbc1" |$si=="ip_address_sbc2" ) { ds_select_dst("2", "8"); $var(new_uri) = "sip:" + $tU + "@" + $dd + ":5060"; $ru=($var(new_uri)); route(RELAY); exit; } # Call from pbx to SBC # Get sbc ip from dispatcher list ds_select_dst("1","4"); $var(new_uri) = "sip:" + $tU + "@" + $dd + ":5060"; $ru=($var(new_uri)); route(RELAY); } When I send a call to the kamailio its routed correctly to the first pbx. But when I kill the asterisk process on the first pbx, an invite is still send by Kamailio to the first pbx. Maybe I am assuming incorrectly that when the dispatcher does not react to the ds_ping it will be set to "inactive" and not be selected by the ds_select_dst command... Or am I thinking to easy and do I need to configure some actions in the failure route? Pretty sure I'm doing something wrong, but cant see where and have not been able to find the information. Tips are appreciated. Rgds, Gertjan Wolzak

onsend_route showing wrong answer after forking
by Aymeric Moizard 26 Sep '18

26 Sep '18

Hi, I'm experimenting "onsend_route" with "onsend_route_reply=yes" to improve my logs. I was surprised to see that "onsend_route" doesn't always display the "forwarded" answer after negative final answers. The documentation seems to indicate that this route will execute only if "the received reply is sent out". -as I'm forking, the final 6xx answer is not "forwarded" immediatly... and I guess this is the reason it doesn't show. Here comes a real strange use-case: With forking enabled, only the last answer will appear in the "onsend_route", however, in some case, this is NOT the answer being forwarded. Example: 1/ receive 603 decline from branch1 2/ a CANCEL is sent on branch2 3/ a 487 Request Terminated is received on branch2 What happens: 1/ onsend_route is showing "487 Request Terminated" 2/ 603 Decline is forwarded (as expected) The documenation say: "If set to 1 (yes, on), onsend_route block is executed for received replies that are sent out. Default is 0." This doesn't look to be correct. (either the doc, or the code?) Is there any possibility to install a log in the script that would log ALL *exact* replies being sent: 1/ the real forwarded ones 2/ and also the ones sent by kamailio directly. May be this is possible with some "event_route"? Tks a lot! Aymeric -- Antisip - http://www.antisip.com

Dispatcher Questions
by Duarte Rocha 26 Sep '18

26 Sep '18

Greetings, I have some questions about Dispatcher0s modules general behaviours. Can Dispatcher use two tables to read values from? If I can't use two tables, is it possible to read them from a Mysql View? I want to be able to have a Gateway belonging to more than one Gateway Set. By doing so, in the table, the gateway will be repeated but with different groups. How will the probing work in this scenario? Will the Gateway be probed multiple times? Thanks for your help. Cheers

TM Module timing question
by Igor Olhovskiy 25 Sep '18

25 Sep '18

Hi! A bit lost in timers for TM module Idea is following I want to have dial timeout for 30 seconds, but only if I received 100 Trying in reply to INVITE. If no 100 Trying is received - I want timeout to be like 2 seconds. 100 Trying is indicator for me, that other side is alive. As I got, fr_timer and fr_inv_timer is not what I’m looking for.

htable event routes behavior
by Володимир Іванець 25 Sep '18

25 Sep '18

Hello all, I have following configuration: 1. Htable which loads from MySQL DB and has autoexpire setting. *modparam("htable", "htable", "tl_connect_users=>size=4;autoexpire=120;dbtable=some_htable")* 2. Regular *route[SOME_ROUTE]* with sole logic. 3. *event_route[htable:mod-init]* 4. *event_route[htable:expired: some_htable]* I use while loop in *event_route[htable:mod-init]* to extract stored values from htable, assign them to *$var(some_variable)* and call *SOME_ROUTE* to perform some action for all of them on Kamailio start up. *SOME_ROUTE* has *$sht(some_htable =>$var(some_variable)) = "enabled"* line to add expired value back to the htable. The pboblem is when* event_route[htable:expired: some_htable]* triggers *SOME_ROUTE*. Values are not being added to htable. Hovewer if I will try to manipulate values for key_name or key_value by adding some character new item will be insert to the htable. Does anybody know if behavior is correct when exactly same value can not be inserted back to htable on it's expired event? Thanks a lot!

Help with kamailio/freeswitch
by David Villasmil 25 Sep '18

25 Sep '18

Hello guys, I know this is kamailio's mailing list, but I'm getting no answer on freeswitch, and i thought someone here has probably done this is the past. I have a proxy in front of freeswitch. I want freeswitch to use the proxy for everything including the termination to my provider. If I configured the gateway like this: <include> <gateway name="myprovider"> <param name="username" value="username" /> <param name="auth-username" value="username"/> <param name="password" value="password" /> <param name="register" value="true"/> <param name="caller-id-in-from" value="true"/> <param name="from-domain" value="myprovider.com"/> <param name="realm" value="myprovider.com"/> <param name="register-proxy" value="myproxy.domain.com"/> </gateway> </include> The registration works properly, the REGISTER goes to the proxy like REGISTER sip:myprovider.com;transport=udp SIP/2.0 and the proxy forwards it fine, and registration works great. But when i try to call via this gateway, the call goes STRAIGHT to the provider! If, on the other hand, i configure my gateway as: <include> <gateway name="myprovider"> <param name="username" value="username" /> <param name="auth-username" value="username"/> <param name="password" value="password" /> <param name="register" value="true"/> <param name="caller-id-in-from" value="true"/> <param name="from-domain" value="myprovider.com"/> <param name="realm" value="myprovider.com"/> <param name="register-proxy" value="myproxy.domain.com"/> <param name="proxy" value="myproxy.domain.com"/> </gateway> </include> Registration does NOT work, because the uri is: REGISTER sip:myproxy.domain.com;transport=udp SIP/2.0 Because there is no registrar on that proxy!

by Duarte Rocha 24 Sep '18

24 Sep '18

Greetings, I'm using subst_hf() function to do some search and replace and i want to identify a undifined amount of digits after a string (ex: string=123123). Everywhere i look, the right way seems to be \d so i'm doing subst_hf("Via","/;string=\d/substitution_string/", "a"); It doesn't seem to work. Any ideas why? Best Regards, Duarte Rocha
