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

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!

Hello! I need to get some data via RPC to Kamailio inside by external event. But it seems long values of body brakes something: loadmodule "xhttp.so" loadmodule "jsonrpcs.so" modparam("jsonrpcs", "transport", 0) 1) event_route[xhttp:request] { ... jsonrpc_exec('{"jsonrpc": "2.0", "method": "core.psx", "id": 1}'); xlog("L_ERR","RPC code: $jsonrpl(code) \n"); xlog("L_ERR","RPC text: $jsonrpl(text) \n"); xlog("L_ERR","RPC body: $jsonrpl(body) \n"); return; } But in result I do not have body: Sep 21 14:27:55 /usr/sbin/kamailio[16140]: ERROR: <script>: RPC code: 200 Sep 21 14:27:55 /usr/sbin/kamailio[16140]: ERROR: <script>: RPC text: OK 2) If I request core.uptime I have something in body: event_route[xhttp:request] { ... jsonrpc_exec('{"jsonrpc": "2.0", "method": "core.uptime", "id": 1}'); xlog("L_ERR","RPC code: $jsonrpl(code) \n"); xlog("L_ERR","RPC text: $jsonrpl(text) \n"); xlog("L_ERR","RPC body: $jsonrpl(body) \n"); return; } Sep 21 14:37:17 /usr/sbin/kamailio[22683]: ERROR: <script>: RPC code: 200 Sep 21 14:37:17 /usr/sbin/kamailio[22683]: ERROR: <script>: RPC text: OK Sep 21 14:37:17 /usr/sbin/kamailio[22683]: ERROR: <script>: RPC body: {"jsonrpc":"2.0","result":{"now":"Fri Sep 21 14:37:17 2018","up_since":"Fri Sep 21 14:37:16 2018","uptime":1},"id":1} [root@kamailio]# kamailio -v version: kamailio 5.1.2 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. -- BR, Denys Pozniak

Include parameters in replies
by Duarte Rocha 21 Sep '18

21 Sep '18

Greetings, I need to to include some routing information (Two Id's, example "id_in=10;id_out=72") to be read later by Kamailio in every Request (Except the first one and in every Reply. For the requests, i'm including this info as parameters in the Record-Route and i'm reading it later in the Route Headers. For replies i thought about using the Via header. I'm using subst_hf() and i'm having success adding the parameter to Via in the requests. However, it does not seem the best idea since i breake the routing when i add the parameter. I wanted to avoid using custom headers for this since i can't really be sure that they won't be erased by any client's CPE or endpoint. Any ideas on this ? Thanks Cheers, Duarte Rocha

re- double record route
by Wilkins, Steve 19 Sep '18

19 Sep '18

Hi Henning, Yes I do have that enabled. What is happening is that one of the providers on IOS is sending a double record route on the INVITE, but it is getting lost somewhere so when I send a 'BYE', I get a "404 not here". When I look at the SIP message I see only one of the record routes from the INVITE, therefore my assumption is, this is what is causing the 404, because everything else looks good.

occasional processing delay and UAC remote registration
by Dmitri Savolainen 19 Sep '18

19 Sep '18

Hi all. i encountered in my 4.1.5 kamailio server some inconstant issue. I have 2 listen address: addr1 for incoming SIP requests and as source addr for remote registration (via UAC module) addr2 for incoming SIP requests only uac config for regs: modparam("uac", "reg_keep_callid", 1) modparam("uac", "reg_random_delay", 120) modparam("uac", "reg_retry_interval", 300) modparam("uac", "reg_timer_interval", 40) i have response time checking tool, that send OPTIONS every second, which immedeately replied by sl_send_reply("200") without any processing. Usualy respose time <1ms. Sometimes (2-3 per day) addr1 stop to response for these OPTIONS (timeout >5sec), while addr2 continue responding with time <1ms. In kamailio.log at this moment bunch of messages like ERROR: uac [uac_reg.c:1034]: uac_reg_tm_callback(): got sip response 403 > while registering ERROR: uac [uac_reg.c:1034]: uac_reg_tm_callback(): got sip response 408 > while registering That is normal: some remotes are broken. The problem is: 1. usually these messages appearing is not the reason of problem, but all problems are while these messages in log 2. it may be on OFF peak / ON peak day period 3. in my test installation i have much more remote failure registration (X 10), and the problem is not manifested more often (but i can catch it 2-3 per day) I think adding more workers for addr1 may help (now 8 worker and 16 CPUs). But it is interesting to understand the source of this issue -- Savolainen Dmitri

Await to INVITE after REGISTER for mobile device which get awake via android/iOS notification messages
by Kristijan Vrban 18 Sep '18

18 Sep '18

Hi, now that many SIP endpoints are mobile devices which usually deep-sleep, and only get awake after Android/iOS own notification messages awake them, what are the best practices to await a a pending INVITE to such a mobile device until it REGISTER after the awake? I currently use a Asterisk a do a simple loop, trying new INVITES every second, but this is not elegant. A nice solution would be a type of queue, where the pending INVITE get send to the new location triggered immediately by the fresh REGISTER from that device to avoid any delay during call setup Kristijan
