Hey, I need all of my kamailio's IPs in Record Routes and i can do that already. What i want to do is add different parameters to each Record-Route. Is that possible?

how to catch attacker using bad request line?
by Juha Heinanen 17 Sep '18

17 Sep '18

In order to be able to fail2ban an attacker that sends tons of SIP requests with malformed request lines, it would need to be possible to generate an appropriate syslog message from config file. I didn't find any sanity module param value that would turn on checking of request line syntax. Any other ideas? As an example, below is what comes to syslog when I send a request that has syntax error on request line. -- Juha Sep 17 14:46:39 char /usr/bin/sip-proxy[9458]: ERROR: <core> [core/parser/msg_parser.c:337]: parse_headers(): bad header field [(null)] Sep 17 14:46:39 char /usr/bin/sip-proxy[9458]: WARNING: <core> [core/receive.c:230]: receive_msg(): parsing relevant headers failed Sep 17 14:46:43 char /usr/bin/sip-proxy[9458]: ERROR: <core> [core/parser/msg_parser.c:337]: parse_headers(): bad header field [(null)] Sep 17 14:46:43 char /usr/bin/sip-proxy[9458]: WARNING: <core> [core/receive.c:230]: receive_msg(): parsing relevant headers failed

Record-Route Parameters
by Duarte Rocha 15 Sep '18

15 Sep '18

Greetings, My Kamailio has 2 IP's and, as such, it will generate two Record-Routes when the Request is relayed. I want to add one parameter to one of the Record Routes and another parameter to the other Record-Route. However, if i use add_rr_param() it will automatically add the parameters to the two Record-Route Headers. Is there a way to do what i want without me re-writing the headers directly ? Cheers, Duarte Rocha

Forward SIP request between two Kamailio servers
by Nathanael Eneroth 14 Sep '18

14 Sep '18

Hi,? I have a simulation setup of 4 VMs in Virtual Box - two UAs and two Kamailio servers. The first UA will register to KAM1, and the second UA will regsiter to KAM2. See the Figure below. UA1<--->KAM1<---->KAM2<---->UA2 int1 int1 int3 int3 int2 int2 I would like KAM1 to forward all SIP requests destined to int3 via KAM2 and vice versa. I am aware of the routing logic in 'kamailio.cfg', but i find rather excessive. Pseudo code of what i'm trying to achieve: if (is_method("INVITE")) { if(dst_ip == int3) set_next_kamailio_server(KAM2) } Or: if (is_method("INVITE")) { if(callee is unkown) ask_kamailio_server(KAM2) } Thanks for all the help

Good evening.

remove_hf("Bla") for all requests
by Sergiu Pojoga 12 Sep '18

12 Sep '18

Hi there, Say I need to remove_hf("User-Agent") for all requests, back and forth. So I add it at the top of *request_route *section. However, replies don't seem to be affected by it. Do I really need to arm a *t_on_reply route* for this simple purpose? "Problem" with that is that *route[RELAY]* already has some *onreply_route* block doing things like *NATMANAGE *for some methods and as far as I know - only one* onreply_route* can be armed for a request? route[RELAY] { ... if (is_method("INVITE|SUBSCRIBE|UPDATE")) { if(!t_is_set("onreply_route")) t_on_reply("MANAGE_REPLY"); } t_relay(); } onreply_route[MANAGE_REPLY] { ... route(NATMANAGE); } Any suggestions? Thanks.

Missing ACC record in case of canceled call forking
by Marco Capetta 12 Sep '18

12 Sep '18

Hi All, I'm facing a strange problem of missing ACC record in case of parallel call forking. The scenario is the following: - A subscriber with 1 device registered - B subscriber with 2 device registered (B1 and B2) CASE 1: - A calls B - B1 and B2 start ringing - A hangups the call before B1 or B2 answers Kamailio generates an ACC record. CASE 2: - A calls B - B1 and B2 start ringing - B1 rejects the call sending back a 486 - B2 is still ringing - A hangups the call before B2 answers Kamailio DOESN'T generate an ACC record. We have Kamailio v5.1.4 with TM module enabled. ACC configuration is the following: modparam("acc", "early_media", 0) modparam("acc", "report_ack", 0) modparam("acc", "report_cancels", 1) modparam("acc", "detect_direction", 1) modparam("acc", "db_flag", 1) modparam("acc", "db_missed_flag", 2) modparam("acc", "failed_transaction_flag", 3) I increased debug level of TM and ACC modules and I added some debug lines as well. The difference between the two calls is that, after the CANCEL sent by A is processed by Kamailio, in CASE 1 I have the following lines: Aug 28 14:21:11 spce proxy[13188]: DEBUG: tm [t_hooks.c:258]: run_trans_callbacks_internal(): DBG: trans=0x7f5a88049198, callback type 512, id 0 entered Aug 28 14:21:11 spce proxy[13188]: DEBUG: acc [acc_logic.c:670]: tmcb_func(): acc callback called for t(0x7f5a88049198) event type 512, reply code 487 Aug 28 14:21:11 spce proxy[13188]: DEBUG: acc [acc_extra.h:63]: free_strar_mem(): Freeing memory, type is 2, message_index 8, index i 0 Aug 28 14:21:11 spce proxy[13188]: DEBUG: acc [acc_extra.h:63]: free_strar_mem(): Freeing memory, type is 2, message_index 8, index i 1 Aug 28 14:21:11 spce proxy[13188]: DEBUG: acc [acc_extra.h:63]: free_strar_mem(): Freeing memory, type is 2, message_index 8, index i 2 Aug 28 14:21:11 spce proxy[13188]: DEBUG: acc [acc_extra.h:63]: free_strar_mem(): Freeing memory, type is 2, message_index 8, index i 3 Aug 28 14:21:11 spce proxy[13188]: DEBUG: acc [acc_extra.h:63]: free_strar_mem(): Freeing memory, type is 2, message_index 8, index i 4 Those debug lines are not printed for CASE 2. Is there any configuration I'm missing or is it a bug? Thank you very much for your support. Marco
