Asterisk Gateway OPTIONS relay

by Ian French

Hey list, I've been trying the relay OPTIONS messages from an asterisk server through kamailio to clients so to preserve the qualify feature in asterisk. So ASTERISK -----OPTIONS----> KAMAILIO ------------> UA UA ----OK-----> KAMAILIO ---OK-----> ASTERISK But I'm seeing floods of OPTIONS messages between asterisk and kamailio now. So much so that kamailio seems to deadlock introducing 10 -20 second delays in processing messages firstly I've enabled the options.so but this is just enable remote monitoring of the application and in my FROMASTERISK route #!ifdef WITH_ASTERISK # Test if coming from Asterisk route[FROMASTERISK] { # if($si==$sel(cfg_get.asterisk.bindip) # && $sp==$sel(cfg_get.asterisk.bindport)) if ((method==OPTIONS) && (uri=~"sip:.*[@]+.*")) { xlog("L_INFO","Options Reply from $ru to $fu\r\n"); return 1; } if(ds_is_from_list("2")){ $sht(forw=>$ft)=$si; xlog("L_INFO","INVITE: INVITE Passed From [$fu] Asterisk Cluster To [$rm:$au].\n"); return 1; } return -1; } I've included a debug below, stating *RFC3261 transaction matching failed. *Can anyone help or advise on how I should solve this Thanks in advance Ian KamP /usr/local/sbin/kamailio[19288]: DEBUG: <core> [parser/msg_parser.c:630]: SIP Request: KamP /usr/local/sbin/kamailio[19288]: DEBUG: <core> [parser/msg_parser.c:632]: method: <OPTIONS> KamP /usr/local/sbin/kamailio[19288]: DEBUG: <core> [parser/msg_parser.c:634]: uri: <sip:XXXXXXXX@P.P.P.P:5060> KamP /usr/local/sbin/kamailio[19288]: DEBUG: <core> [parser/msg_parser.c:636]: version: <SIP/2.0> KamP /usr/local/sbin/kamailio[19288]: DEBUG: <core> [parser/parse_via.c:1287]: Found param type 232, <branch> = <z9hG4bK50c02ae3>; state=6 KamP /usr/local/sbin/kamailio[19288]: DEBUG: <core> [parser/parse_via.c:1287]: Found param type 235, <rport> = <n/a>; state=17 KamP /usr/local/sbin/kamailio[19288]: DEBUG: <core> [parser/parse_via.c:2300]: end of header reached, state=5 KamP /usr/local/sbin/kamailio[19288]: DEBUG: <core> [parser/msg_parser.c:515]: parse_headers: Via found, flags=2 KamP /usr/local/sbin/kamailio[19288]: DEBUG: <core> [parser/msg_parser.c:517]: parse_headers: this is the first via KamP /usr/local/sbin/kamailio[19288]: DEBUG: <core> [receive.c:145]: After parse_msg...

Re: [SR-Users] kamailio loadbalancer with TLS problem forwarding INVITE back to UA

I do not understand that. fix_nated_register stores both info: the original contact + src-ip:port:transport. After lookup(), the Request-URI is filled with the original contact, but $du (destination URI, internally used by Kamailio for routing) is populated with src-ip:port:transport. Thus, Kamailio should use the $du to find the TCP connection. Anyway, TLS debugging is always difficult. I suggest to try to make it running with TCP. If TCP works, TLS will work too. regards Klaus > > I need to use fix_nated_register() because the UA will be behind NAT in the future.

Wrong src-adress in packets sent from Kamailio when using listen=

by Johan Wilfer

Hi! I've the following setup: Teleco <-> Kamailio <-> Asterisk(s) The proxy has one public IP (say 1.2.3.4) and one private (10.0.0.1). The asterisk-pbx:es has private adresses (10.0.0.2 in this example) I noticed that if I bind like this in kamilio.cfg listen=tcp:1.2.3.4:5060 listen=udp:1.2.3.4:5060 listen=tcp:10.0.0.1:5060 listen=udp:10.0.0.1:5060 Then if a call comes in from the Telco to Kamailio (1.2.3.4), kamailio should forward the SIP-packet from it's private address (10.0.0.1) to asterisk (10.0.0.2) However, the source address of the packets sent from Kamilio to Asterisk is wrong - it uses the public ip. Like this (tcpdump output): 15:02:08.999642 IP 1.2.3.4.sip > 10.0.0.1.5060: SIP, length: 1346 15:02:09.474525 IP 1.2.3.4.sip > 10.0.0.1.5060: SIP, length: 1346 15:02:10.474524 IP 1.2.3.4.sip > 10.0.0.1.5060: SIP, length: 1346 15:02:12.474525 IP 1.2.3.4.sip > 10.0.0.1.5060: SIP, length: 1346 Obviously kamailio doesn't get any answers here. The packet goes out of the right interface, but with the wrong src-address. However, if I remove the lines with "listen=" in kamailio.cfg to allow kamilio to bind to all interfaces the src-address is correct and everything works! (I've also done some tests with icmp and telnet and the src-addr seems right in all these cases.) Is this a bug or am I missing something here? -- Johan Wilfer

Xhttp_pi DB Query Clause Operators

by Simpson Chua

Hi, I'm using the xhttp_pi module to query the kamailio user registration table "location". Per the defined clause_cols operators in the module, it doesn't seem possible to achieve a query equivalent to a SQL "contains" or "like". An exact match is required to query the record; e.g., http://xxxxxxx/location/QueryContacts?cmd=on&0=sip:8675309@a.b.c.d:5060;tra…. Is my understanding correct that there is no way to match on an regular expression? My end goal is to be able to query for a user's AOR and expiration status based on a search string (e.g. 8675309) via a webservice. Can anyone share a better method to do this? Perhaps asynchronously? All feedback is appreciated. Sample contact field: sip:8675309@a.b.c.d:5060;transport=udp Sample Framework: <cmd><cmd_name>QueryContacts</cmd_name> <db_table_id>location</db_table_id> <cmd_type>DB1_QUERY</cmd_type> <clause_cols> <col><field>contact</field><operator>=</operator></col> </clause_cols> <query_cols> <col><field>username</field></col> <col><field>contact</field></col> <col><field>expires</field></col> </query_cols> </cmd> Thanks, Simpson ________________________________ From: "sr-users-request(a)lists.sip-router.org" <sr-users-request(a)lists.sip-router.org> To: sr-users(a)lists.sip-router.org Sent: Thursday, June 27, 2013 5:00 AM Subject: sr-users Digest, Vol 97, Issue 104 Send sr-users mailing list submissions to sr-users(a)lists.sip-router.org To subscribe or unsubscribe via the World Wide Web, visit http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users or, via email, send a message with subject or body 'help' to sr-users-request(a)lists.sip-router.org You can reach the person managing the list at sr-users-owner(a)lists.sip-router.org When replying, please edit your Subject line so it is more specific than "Re: Contents of sr-users digest..."

Kamailio is crashing while parsing Via header

by Krishna Kurapati

Once I increased package memory the crash went away. 4(21729) DEBUG: <core> [parser/msg_parser.c:623]: SIP Request: 4(21729) DEBUG: <core> [parser/msg_parser.c:625]: method: <MESSAGE> 4(21729) DEBUG: <core> [parser/msg_parser.c:627]: uri: <sip:50.62.72.174:15060;transport=udp> 4(21729) DEBUG: <core> [parser/msg_parser.c:629]: version: <SIP/2.0> 0(21722) ALERT: <core> [main.c:788]: child process 21729 exited by a signal 11 0(21722) ALERT: <core> [main.c:791]: core was generated 0(21722) INFO: <core> [main.c:803]: INFO: terminating due to SIGCHLD (gdb) backtrace #0 qm_detach_free (qm=0x2b7b70759010, size=64) at mem/q_malloc.c:269 #1 qm_malloc (qm=0x2b7b70759010, size=64) at mem/q_malloc.c:386 #2 0x0000000000560fa1 in parse_via ( buffer=0x8c6a3b "SIP/2.0/UDP 50.62.72.174;branch=z9hG4bK3f84.7fd8a5e.0;i=3\r\nVia: SIP/2.0/TCP 75.43.10.221:60659;rport=60660;branch=z9hG4bKPjc9713006b62149648240ed4ea4686b85\r\nMax-Forwards: 16\r\nFrom: <sip:578626051@50.6"..., end=0x8c6e7d "", vbody=0x2b7b7077ae90) at parser/parse_via.c:2540 #3 0x0000000000538e68 in get_hdr_field ( buf=<value optimized out>, end=0x8c6e7d "", hdr=0x2b7b707aa9c0) at parser/msg_parser.c:140 #4 0x0000000000539ac9 in parse_headers (msg=0x2b7b7079b100, flags=2, next=<value optimized out>) at parser/msg_parser.c:351 #5 0x000000000053af8d in parse_msg ( buf=<value optimized out>, len=<value optimized out>, msg=0x2b7b7079b100) at parser/msg_parser.c:650 #6 0x000000000049a2ef in receive_msg ( buf=0x8c6a00 "MESSAGE sip:50.62.72.174:15060;transport=udp SIP/2.0\r\nVia: SIP/2.0/UDP 50.62.72.174;branch=z9hG4bK3f84.7fd8a5e.0;i=3\r\nVia: SIP/2.0/TCP 75.43.10.221:60659;rport=60660;branch=z9hG4bKPjc9713006b621496482"..., len=1149, rcv_info=0x7fff932d32e0) at receive.c:144 #7 0x0000000000528666 in udp_rcv_loop () at udp_server.c:557 #8 0x0000000000464daa in main_loop () at main.c:1638 #9 0x0000000000467adc in main (argc=<value optimized out>, argv=<value optimized out>) at main.c:2566
