Locate UA in usrloc table
by Vitaliy Aleksandrov 03 Oct '12

03 Oct '12

Hi all. Is there any easy method to find if somebody with $si:$sp is registered (usrloc->received.ip == $si, usrloc->received.port == $sp) ? reg_fetch_contacts uses uri as search key, but in my case I don't have it. The only way I know is to write a module that will use "get_all_ucontacts" function exported by usrloc module in its API.

Hi, After implementing a "Call limit" application with the following config: #!ifdef WITH_CALL_LIMIT modparam("dialog","enable_stats",1) modparam("dialog","dlg_flag", 4) modparam("dialog","hash_size", 4096) modparam("dialog", "profiles_with_value","callquota") modparam("dialog", "default_timeout", 300) modparam("dialog", "dlg_match_mode", 2) modparam("dialog", "detect_spirals", 1) modparam("dialog", "db_mode", 0) #!endif request_route { ................ #!ifdef WITH_CALL_LIMIT if (is_method("INVITE")) { dlg_manage(); $var(100) = 0; get_profile_size("callquota", "$rU", "var(100)"); if ($var(100) >= 5 ) { xlog("DEBUG: Simultaneous calls limit reached"); sl_send_reply("503","Simultaneous calls limit reached"); exit; } set_dlg_profile("callquota","$ru"); if (get_profile_size("callquota", "$var(100)")) { xlog("DEBUG: there are $var(100) total calls for $rU\n"); } } #!endif ............... } Now it passes cleanly when i issue : $kamailio -c but it fails to start with following info: Sep 29 19:37:49 108 /usr/local/sbin/kamailio[1865]: ERROR: <core> [route.c:1216]: fixing failed (code=-1) at cfg:/usr/local/etc/kamailio/kamailio.cfg:507 Sep 29 19:37:49 108 /usr/local/sbin/kamailio[1865]: ERROR: <core> [route.c:1216]: fixing failed (code=-1) at cfg:/usr/local/etc/kamailio/kamailio.cfg:523 line 507 : get_profile_size("callquota", "$rU", "var(100)"); Thanks in advance -- -aft

Hi All, I'm observing a core intermittently at "qm_status (qm=0x786cd000) at mem/q_malloc.c:763" for kamailio version 3.1.0 looking at the backtrace this is occurring while doing a tcp buffer overrun.

Registration Authentication Error
by Nathaniel L Keeling III 30 Sep '12

30 Sep '12

Hello, we are testing the new version of Kamailio, 3.3 and are getting authentication error when trying to register a sip account. We have a db backend in which we used kamctl to add the user to the db. We are using the kamailio.cfg script created during the install with changes for our environment. Is there some other changes required besides the normal. I can see in the logs where everything looks ok except for when it compares the calculated values. I have doubled check the subscriber table and password but to no avail. 11(28548) DEBUG: db_postgres [km_dbase.c:393]: PQclear(1008b8560) result set 11(28548) DEBUG: auth_db [authorize.c:124]: HA1 string calculated: e13d569284e76a33ca63e4d6203f844a 11(28548) DEBUG: auth [api.c:211]: check_response: Our result = '18210b5da2b3d27e6ba50977072599ea' 11(28548) DEBUG: auth [api.c:221]: check_response: Authorization failed Thanks Nathaniel

Kamailio 3.3 presence with resource lists and integrated XCAP
by Sangeeta Shah 28 Sep '12

28 Sep '12

Hello All, I am trying to configure Kamailio v 3.3 to serve as a presence server with resource lists and integrated XCAP. I followed the respective module documentation and am trying to test with the Boghe IMS client. I just can't get it to work! I think I still don't have everything I need in the config file to handle the xcap documents. Attached is the debug log from the server. If someone has had luck setting up the presence server with integrated xcap and resource lists please take a few minutes to take a look at the log file and see if you can help me out. I am also posting the xcap portion of the config file: #!ifdef WITH_XCAPSRV ##!define WITH_XHTTPAUTH event_route[xhttp:request] { xdbg("===== xhttp: request [$rv] $rm => $hu\n"); #!ifdef WITH_XHTTPAUTH if (!www_authorize("10.50.251.12", "subscriber")) { www_challenge("10.50.251.12", "0"); exit; } #!endif if($hu=~"^/xcap-root/") { set_reply_close(); set_reply_no_connect(); # xcap ops $xcapuri(u=>data) = $hu; if($xcapuri(u=>xuid)=~"^sip:.+@.+") $var(uri) = $xcapuri(u=>xuid); else if($xcapuri(u=>xuid)=~".+@.+") $var(uri) = "sip:" + $xcapuri(u=>xuid); else $var(uri) = "sip:"+ $xcapuri(u=>xuid) + "@" + $Ri; xlog("===== xhttp: $xcapuri(u=>auid) : $xcapuri(u=>xuid)\n"); if($xcapuri(u=>auid)=="xcap-caps") { $var(xbody) = "<?xml version='1.0' encoding='UTF-8'?> <xcap-caps xmlns='urn:ietf:params:xml:ns:xcap-caps'> <auids> <auid>rls-services</auid> <auid>pidf-manipulation</auid> <auid>xcap-caps</auid> <auid>pres-rules</auid> </auids> <extensions> </extensions> <namespaces> <namespace>urn:ietf:params:xml:ns:rls-services</namespace> <namespace>urn:ietf:params:xml:ns:pidf</namespace> <namespace>urn:ietf:params:xml:ns:xcap-caps</namespace> <namespace>urn:ietf:params:xml:ns:pres-rules</namespace> </namespaces> </xcap-caps>"; xhttp_reply("200", "ok", "application/xcap-caps+xml", "$var(xbody)"); exit; } #!ifdef WITH_XHTTPAUTH # be sure auth user access only its documents if ($au!=$(var(uri){uri.user})) { xhttp_reply("403", "Forbidden", "text/html", "<html><body>$si:$sp</body></html>"); exit; } #!endif switch($rm) { case "PUT": #xcaps_put("$var(uri)", "$hu", "$rb"); #if($xcapuri(u=>auid)=~"pres-rules") #{ # xlog("===== xhttp put: refreshing watchers for $var(uri)\n"); # pres_update_watchers("$var(uri)", "presence"); # pres_refresh_watchers("$var(uri)", "presence", 1); #} xcaps_put("$var(uri)", "$var(doc_uri)", "$rb"); if($xcapuri(u=>auid)=~"pres-rules") { pres_update_watchers("$var(uri)", "presence"); pres_refresh_watchers("$var(uri)", "presence", 1); } else if ($xcapuri(u=>auid)=~"resource-lists" || $xcapuri(u=>auid)=~"rls-services") { rls_update_subs("$var(uri)", "presence"); } exit; break; case "GET": xlog("===== xhttp: get $var(uri) => $hu\n"); xcaps_get("$var(uri)", "$hu"); exit; break; case "DELETE": xcaps_del("$var(uri)", "$hu"); if($xcapuri(u=>auid)=~"pres-rules") { xlog("===== xhttp del: refreshing watchers for $var(uri)\n"); pres_update_watchers("$var(uri)", "presence"); pres_refresh_watchers("$var(uri)", "presence", 1); } exit; break; } } # http ops xhttp_reply("200", "ok", "text/html", "<html><body>OK: $si:$sp</body></html>"); exit; } -- Sangeeta Shah

DB accounting missing if t_newtran() is called explicitly
by Andrew Pogrebennyk 28 Sep '12

28 Sep '12

Hi, I have found recently that in order to detect retransmits I have to create a transaction explicitly when the request comes in: force_rport(); if(!t_check_trans()) t_newtran(); sl_send_reply("100", "Trying"); xlog("L_INFO", "New request - $ci\n"); it appears like there are carriers or UAs that do not honor the T1 retransmission interval retransmit the INVITE sooner than proxy creates a transaction in t_relay(). And since we are counting concurrent calls, we count the same call multiple times, which is not good. But with this patch we've faced another sporadic problem - if the transaction is created beforehand the accounting record is lost.. we use acc_db mode and set flag to account the transaction. And there are no errors in kamailio log but no insert into acc in mysql binlog either. I wasn't successful reproducing it in the lab systems with identical setup. Is anybody here perhaps aware of some limitation in acc module or callbacks which makes a transaction created beforehand not accountable? On a related note, it could make sense to create a transaction implicitly if dlg_manage() is called to avoid counting same call many times, I just don't know yet how common this issue is in real life.

SRV record in via header not resolving.
by Jijo 28 Sep '12

28 Sep '12

Hello, I'm observing that Via Header domain name of type SRV is resolving as DNS A. I looked at the code and it does support only A. It is basically setting to default SIP port check_via_address which is causing DNS A query. Is there any specific reason to do so? I changed the code to support SRV as below and working fine. static int check_via_address(struct ip_addr* ip, str *name, unsigned short port, *short proto*, int resolver) { : : //if (port==0) port=SIP_PORT; if (resolver&DO_DNS){ DBG("check_via_address: doing dns lookup\n"); /* try all names ips */ he=sip_resolvehost(name, &port, *(char *) &proto*); /* don't use naptr */ if (he && ip->af==he->h_addrtype){ for(i=0;he && he->h_addr_list[i];i++){ if ( memcmp(&he->h_addr_list[i], ip->u.addr, ip->len)==0) return 0; } } } : : : } /* check if IP address in Via != source IP address of signaling */ int received_test( struct sip_msg *msg ) { int rcvd; rcvd=msg->via1->received || check_via_address(&msg->rcv.src_ip, &msg->via1->host, msg->via1->port,* msg->via1->proto*, received_dns); return rcvd; } Thanks Jijo

Kamailio sip domain
by Burak ÖZTÜRK 28 Sep '12

28 Sep '12

Hi, What is the sip domain in kamctlrc file? Can I change it whatever I want? Is it must be a valid sip domain? Can I give a name like "mysipdomain.com", but there is no server with this name?
