INFO: stun_parse_header: incomplete header of STUN message
by Pan Christensen 29 May '18

29 May '18

Hello! After proxying a REGISTER from a WebRTC client to our SIP backend, the backend starts sending keepalives. Every 30 seconds I get a log entry in Kamailio saying: "INFO: stun [kam_stun.c:169]: stun_parse_header(): INFO: stun_parse_header: incomplete header of STUN message". Here's one such packet: No. Time Source Destination Protocol Length Info 1 0.000000 xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy UDP 60 5060 ? 15060 Len=4 Frame 1: 60 bytes on wire (480 bits), 60 bytes captured (480 bits) Ethernet II, Src: JuniperN_4f:3f:f0 (40:a6:77:4f:3f:f0), Dst: 02:81:64:58:cf:d1 (02:81:64:58:cf:d1) Internet Protocol Version 4, Src: xxx.xxx.xxx.xxx, Dst: yyy.yyy.yyy.yyy 0100 .... = Version: 4 .... 0101 = Header Length: 20 bytes (5) Differentiated Services Field: 0x00 (DSCP: CS0, ECN: Not-ECT) Total Length: 32 Identification: 0x5bf5 (23541) Flags: 0x4000, Don't fragment Time to live: 56 Protocol: UDP (17) Header checksum: 0x2fc3 [validation disabled] [Header checksum status: Unverified] Source: xxx.xxx.xxx.xxx Destination: yyy.yyy.yyy.yyy User Datagram Protocol, Src Port: 5060, Dst Port: 15060 Source Port: 5060 Destination Port: 15060 Length: 12 Checksum: 0xfa28 [unverified] [Checksum Status: Unverified] [Stream index: 0] Data (4 bytes) 0000 00 00 00 00 ....

IMHO it's not possible to send error response * because the transaction ID is not available. */ return FATAL_ERROR; } ... Could someone please explain what's wrong? Med vennlig hilsen Pan B.

Dialplan module for load balancing
by igor.potjevlesch＠gmail.com 29 May '18

29 May '18

Hello, I'm maybe confused on how to use dialplan module. I have a dialplan setup for a long time now and I'd like to add a new rule with the same match_exp than an existing one but with a different repl_exp. If I set the same priority, the latest entry is used systematically. If I set priority +1, the new rule is never used. The goal is having two rules and alternatively reply with one or the other repl_exp. Is it possible? Regards, Igor.

Pkg memory stats
by Konstantin Polyakov 29 May '18

29 May '18

Hello, Could somebody explain what do numbers mean for command "kamcmd mod.stats all pkg"? Is there somewhere documentation about that? I can see the following information. " Module: xlog { mod_init(213): 4104 xlog_fixup_helper(533): 3176 xdbg_fixup_helper(499): 632 Total: 7912 } " I guess that numbers after colon are bytes. But what do numbers in (213) mean? When I use command "kamcmd pkg.stats", I got absolutely different numbers which don't match previous statistics? What is wrong? What is the best way to analyze pkg memory usage? Thank you Best regards Konstantin

Realtime Extensions SQLITE
by Benjamin Marty 29 May '18

29 May '18

I compiled a fresh Asterisk 13.18 certified with res_config_sqlite. I configured following: extconfig.conf [settings] sippeers => sqlite,asterisk,ast_config res_config_sqlite.conf [general] dbfile => /home/myuser/database.db On Bootup it gives the following error: [May 29 17:07:14] WARNING[32444]: res_config_sqlite.c:1206 realtime_multi_handler: no such table: ast_config Is the sqlite module deprecated or is my configuration wrong? Couldn't really find any documentation on that topic. The table ast_config is definitely present in the sqlite file.

Serial forking
by igor.potjevlesch＠gmail.com 29 May '18

29 May '18

Hello, I know that the default behaviour of two aliases in kamailio.aliases result in parallel forking. I'm wondering if its possible to do serial forking instead? For example, in case that the first INVITE has no 180/183, or neither 100 Trying, then send the INVITE to the second entry? Regards, Igor.

Switching form UDP to TCP causes authentication errors
by Wilkins, Steve 29 May '18

29 May '18

Hello All, When I switched from UDP to TCP I started getting Authentication Errors, Asterisk responds to an INVITE via Kamailio with a '401 Unauthorized', but Kamailio does nothing with it. Processing just stops near WITH_BLOCK401407. Shouldn't the 401 be relayed so a new INVITE can be sent? Thank you.

by Valentin Christoph 29 May '18

Hi, The function build_p_associated_uri() in module ims_isc filters for TEL URIs. Why are not ALL unbarred IMPUs added, but only TEL URIs? Is this specified in some 3GPP spec?

Carrierroute Wholesale termination issue
by riaz hasan 29 May '18

29 May '18

Hello, I am facing an issue with kamailio carrierroute.I have a setup where multiple asterisk is behind a kamailio server.I am able to dispatch the load by using carrierroute. Its working perfectly for retail users.But problem is its not working for wholesale users.I am attaching the dump for wholesale client. here is a little descrption for the shark:- 192.151.149.102 is the wholesale client ip. 46.166.139.60:4848 is kamailio server. 46.166.139.60:3628 is asterisk server. when 192.151.149.102 sends invite to 46.166.139.60:4848 [Kamailio] we are getting 401. [dump2.pcap] when 192.151.149.102 sends invite to 46.166.139.60:3628 [Direct Asterisk ] we are getting 200. [dump.pcap] here is the code i am using for load balancing:- route[Carrer] { #!ifdef WITH_CARRIERROUTE if (!cr_route("default", "default", "$rU", "$rU", "call_id")) { xlog("L_ERR", "cr_route failed\n"); exit; } #!endif $avp(s:host)= $rd+":"+$rp; t_on_failure("1"); if (!t_relay()) { sl_reply_error(); }; } failure_route[1] { revert_uri(); #!ifdef WITH_CARRIERROUTE if (!cr_next_domain("default", "default", "$rU", "$avp(s:host)", "$T_reply_code", "$avp(s:domain)")) { xlog("L_ERR", "cr_next_domain failed\n"); exit; } if (!cr_route("default", "default", "$rU", "$rU", "call_id")) { xlog("L_ERR", "cr_route failed\n"); } t_on_failure("1"); route(NASIR); exit; #!endif $avp(s:host)= $rd+":"+$rp; if (!t_relay()) { xlog("L_ERR", "t_relay failed-custom\n"); exit; }; }

S-SCSF not forwarding SIP packets to AS
by John M 29 May '18

29 May '18

Hi All, My setup consists of Kamailio P-CSCF,I-SCSF , S-CSCF and OpenIMS HSS nodes and I have configured application server details and trigger point on HSS. I am using Boghe IMS client SIP validation. Whenever the client sends a REGISTER, messages are not reaching AS. In S-SCSF log files, I am seeing " isc_match_filter_reg(): No REGISTER match found in filter criteria" and " isc_check_filter_criteria(): ifc_checker_trigger: - group compromised, skipping to next group" error message.
