Hi, I am using SER iptel as a SIP proxy. I have few doubts regarding ser.cfg configuration file. 1. I am having two config variables, say $a and $b. Can't I do any comparison of the two in any if loop? e.g. [if ($a == $b)] or something similar. 2. I exported a function from a module say func1( ). It works perfectly fine if I pass a static value in it but corrupts the value if I pass a variable thru it.e.g. func1("11") will work fine but $a = '11' and func1("%$a") will not work. … [View More]

Asterisk Gateway OPTIONS relay
by Ian French 28 Jun '13

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 … [View More]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 27 Jun '13

27 Jun '13

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.… [View More]

Xhttp_pi DB Query Clause Operators
by Simpson Chua 27 Jun '13

27 Jun '13

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 … [View More]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?
