Kamailio can not read to_tag at BYE request
by Yuriy Gorlichenko 11 Nov '15

11 Nov '15

Hello. I have some one provider that sends me BYE request with to_tag that kamailio can not parse IP my.pro.vi.der.5060 > my.ser.vi.ce.5060: UDP, length 406 E.......x...S.0X_..L......8.BYE sip:0987654321@my.ser.vi.ce SIP/2.0 Via: SIP/2.0/UDP my.pro.vi.der:5060;branch=z9hG4bKsj7bv820c0s18k8a15q1sd000ag33.1 Call-ID: 00137fb21f65f19a3094c38b30d80f5c CSeq: 1479 BYE From: <sip:1234567890@my.pro.vi.der>;tag=SDi9r0899-5ci36vojn0 To: <sip:0987654321@my.pro.vi.der>;tag=as6635bbe1 Reason: Q.850;cause=16;text="Normal call clearing" Max-Forwards: 69 Content-Length: 0 So I guess that problem in provider (may be ";" with another code) But may be we have some instruments to get tag (without parsing strings in a config file or something like that )

Removing transport=TLS from the contact header
by Rizwan Khan 10 Nov '15

10 Nov '15

I want to remove the transport=TLS from the contact header. How can I do that inside Kamailio? The flow is an under: Client --------> Kamailio -------------> FS TLS UDP Client <-------- Kamailio <------------- FS TLS UDP FS gets a request on udp but it complains about TLS profile as the contact header has the transport=TLS. Since its receing traffic on UDP, if I only get rid of the value from the Contact Header, it would be great. Thanks, Rizwan Khan

Header field Contact not changed on kamailio 4.2
by Зуев Михаил 09 Nov '15

09 Nov '15

Hi all, I need to modify the host part of a contact header. I'm trying something like: route { ..... if (remove_hf("Contact")){ if (insert_hf("Contact: rn", "Contact")) xlog("Contact modified"); } if (!t_relay("YYY.YYY.YYY.YYY","5060")) { sl_reply_error(); } ...... } When i look SIP DUMP on YYY.YYY.YYY.YYY side i see older Contact field. I try subst_hf with regexp, subst and simply remove Contact, all this does not work. What i am doing wrong? -- С уважением Зуев Михаил

Re: [SR-Users] Branch & Forking
by Daniel-Constantin Mierla 09 Nov '15

Hello, the aggregation of replies for a parallel fork is done automatically and negative responses are absorbed. Can you send a ngrep trace of a call where you found that the negative response of a branch is not absorbed in case a branch answered?

Question about siremis
by Bruno Salzano 09 Nov '15

09 Nov '15

Hello, i hope not to be OT. However I noticed that latest release is 4.2.0 and that this version is compatible with kamailio 4.2.x. Is it compatible also with 4.3.x? Another question is related to Siremis development: this great webapplication is developed using PHPOpenBiz Framework. From several days the PHPOpenBiz website is down. So will Siremis development continue on PHPOpenBiz? Is there some release schedule? Best Regards Bruno

Preprocessor define puzzle
by Alex Balashov 09 Nov '15

09 Nov '15

Hi, I've got: # define WITH_VENDOR_ROUTING_LNPOIP at the top of my config. This is intended to mean that this constant is commented out and disabled ('# define' vs. '#!define'), and tests correctly in a given request route. Later: route[STAGE_3] { ... #!ifdef WITH_VENDOR_ROUTING_LNPOIP xlog("L_INFO", "LNPOIP ENABLED STAGE 3\n"); #!else xlog("L_INFO", "LNPOIP NOT ENABLED STAGE 3\n"); #!endif route(OUTBOUND_VENDOR_SELECT); } This tests correctly: Nov 8 21:17:54 centosity6 /usr/local/sbin/kamailio[12296]: INFO: LNPOIP NOT ENABLED STAGE 3 However, in route[OUTBOUND_VENDOR_SELECT]: #!ifdef WITH_VENDOR_ROUTING_LNPOIP xlog("L_INFO", "LNPOIP ENABLED\n"); #!else xlog("L_INFO", "LNPOIP NOT ENABLED\n"); #!endif This prints: Nov 8 21:17:54 centosity6 /usr/local/sbin/kamailio[12296]: INFO: LNPOIP ENABLED Nov 8 21:17:54 centosity6 /usr/local/sbin/kamailio[12296]: INFO: LNPOIP NOT ENABLED ... which I must admit is quite puzzling. Looks like it's both defined and not defined. Running 4.3:16be09c here.

by Jan Hazenberg 06 Nov '15

06 Nov '15

Daniel, I'm currently running a kamailio 4.2.3 with htable enabled and i'm trying to load data into a hash table using the "event_route[htable:mod-init]". When i try to execute a sql_xquery kamailio generates a core dump on startup. Example event_route: event_route[htable:mod-init] { sql_xquery("kamailio", "SELECT id,number FROM blacklist_number", "blacklist_number"); } Log output when starting kamailio: 0(16905) INFO: rr [../outbound/api.h:54]: ob_load_api(): Failed to import bind_ob 0(16905) INFO: rr [rr_mod.c:160]: mod_init(): outbound module not available 0(16905) INFO: usrloc [hslot.c:53]: ul_init_locks(): locks array size 1024 0(16905) INFO: auth [auth_mod.c:350]: mod_init(): auth: qop set, but nonce-count (nc_enabled) support disabled 0(16905) INFO: permissions [parse_config.c:251]: parse_config_file(): file not found: //etc/kamailio/permissions.allow 0(16905) INFO: permissions [permissions.c:608]: mod_init(): default allow file (//etc/kamailio/permissions.allow) not found => empty rule set 0(16905) INFO: permissions [parse_config.c:251]: parse_config_file(): file not found: //etc/kamailio/permissions.deny 0(16905) INFO: permissions [permissions.c:617]: mod_init(): default deny file (//etc/kamailio/permissions.deny) not found => empty rule set 0(16905) INFO: pike [pike.c:115]: pike_init(): PIKE - initializing 0(16905) INFO: pike [ip_tree.c:88]: init_lock_set(): probing 256 set size 0(16905) INFO: <core> [udp_server.c:175]: probe_max_receive_buffer(): SO_RCVBUF is initially 124928 0(16905) INFO: <core> [udp_server.c:225]: probe_max_receive_buffer(): SO_RCVBUF is finally 249856 0(16905) INFO: rtpproxy [rtpproxy.c:1593]: rtpp_test(): rtp proxy <udp:10.1.8.20:22000> found, support for it enabled 0(16905) NOTICE: <script>: Startup event route! Segmentation fault (core dumped) Could this be a bug? Or is there a better way to load data from a custom table into a hashtable on startup. Thanks, Jan Hazenberg
