[OpenSER-Users] issue - remote sip client must re-register after failover in Openser Registrar HA config
by Naija Man 06 Mar '08

06 Mar '08

Hi friends, I am having problems setting up seamless openser registrar failover. I am trying to setup OpenSER registrar HA using 2 openser registrars v1.3.0behind a Netscaler citrix Load balancer and I cant get the failover scenario to work without re-registration of the remote sip client. I am desperately looking for tips to make this configuration work or any other ideas to achieve SIP registrar HA using OpenSER. Thanks. The setup is configured as active-passive and the 2nd OpenSER becomes active only after a Openser_1 fails and the LB fails-over to the 2nd. The 2 openser servers are SIP registrars for my voice network. REGISTRATION: remote SIP UA ---> remote firewall ---> internet ---> my firewall ---> citrix NA loadbalancer (VIP) ----> openSER_1 \---> openSER_2 1. Remote SIP client configures the LB VIP as the SIP proxy and registers 2. the citrix LB gets the registrations and forwards to the active openser (say, openser_1) 3. openser_1 stores the contact as MIP:port in the mysql database 4. openser_1 replicates the registration to openser_2 (t_replicate) OUT-GOING CALL - before fail-over remote SIP UA <--- remote firewall <--- internet <--- my firewall <--- citrix NA loadbalancer (VIP) <----> openSER_1 ^ openSER_2 | Asterisk 1. call (INVITE) is generated from asterisk and sent to LB VIP 2. the citrix LB gets the INVITE and forwards to the active openser (say, openser_1) 3. openser_1 looks-up the URI in the MySQL database, finds the MIP:port that the registration was received from the LB and forwards the INVITE to that destination. 4. the LB receives the INVITE and forwards it to the remote SIP client OUT-GOING CALL - after fail-over remote SIP UA ---x remote firewall ---x internet ---x my firewall ---x citrix NA loadbalancer (VIP) ----x openSER_1 ^ \-----< openSER_2 | Asterisk 1. call (INVITE) is generated from asterisk and sent to LB VIP 2. the citrix LB gets the INVITE and forwards to the openser now active (openser_2) 3. openser_2 looks-up the URI in the MySQL database, finds the same MIP:port of the LB that was replicated from openser_1 and forwards the INVITE to that destination. 4. the LB receives the INVITE and drops the packet without forwarding it out to the remote SIP client For the outgoing call to work: the remote sip client either has to re-register, so the registration gets passed to openser_2. OR, openser_1 is made active again. Configuration of OpenSER: REGISTRATION: # If this is a registration from the public UA, # then we store it fix_nated_contact(); # use ip address of the packet instead of the sip message force_rport(); # append rport. might not be necessary # save Registration in location table save("location"); xlog("L_DBG", "SipMsgId[$mi] Save Registration: To[$tu] Contact[$ct]\n"); append_hf("CtlRegFwd: \r\n"); # replicate the register message to the backup registrar # if I am the backup, ignore the message if(!t_replicate("sip:openser_2:5060")) { xlog("L_WARN", "SipMsgId[$mi] Fail to replicate Contact[$ct] to fail over registrar\n"); OUTGOING CALL: # Do lookup so it gets to the correct NATed destination if (!lookup("location")) { # this user has not REGISTERed or registration has expired xlog("L_INFO", "SipMsgId[$mi] Send 404-Not Found (Msg rejected because user not found)\n"); sl_send_reply("404", "Not Found"); exit; }; # keep track of reply t_on_reply("11"); if (!t_relay()) { xlog("L_DBG", "SipMsgId[$mi] Failed t_relay. Do sl_reply_error.\n"); sl_reply_error(); }; Thank you for your anticipated help. Regards, Buki A

[Serusers] e2e cancel - ghost calls
by Nuno Ribeiro 06 Mar '08

06 Mar '08

Hi all, I'm having a problem related with the "early" CANCEL's. The scenario is the following one : A PSTN call to a SIP phone. When the PSTN decides to cancel the call only a right after initiating, the PSTN will send the CANCEL message to the SER but this is discarded and not forwarded to the correct path to the SIP Phone. So what happens is that we have a ghost call.... The PSTN has already cancelled the call but the SIP phone continues to ring. The code that I have in the SER script is really simple: if(subst_uri('/^sip:(\+[0-9]+)@ 192.168.20.69.*user=phone$/sip:\1@ptinovacao.pt/i')){ record_route(); loose_route(); t_relay_to_udp("192.168.20.5", "5060"); break; } In the log file I see that: RFC3261 transaction matching failed t_lookup_request: no transaction found e2e_cancel: e2e cancel proceeding Could you help me? Thanks in advance. Best Regards, -- Nuno Ribeiro

[OpenSER-Users] WeSIP ans Openser configurations problems
by bsb093 06 Mar '08

06 Mar '08

Hi, I am new in this area and as expected I am having real problem with setting up the Openser with WeSIP . I have installed OpenSER 1.2.0 on debian platform and download WeSIP from WeSIP website. When trying to run Openser I get an error that fifo="tmp/openser_fifo" line has parse error (in the openser.cfg). Therefore I remove this line and instead I added "modparam("mi_fifo", "fifo_name", "/tmp/openser_fifo")". Why do I get the error message if that is the same in the examples? Second, "modparam("seas", "listen_sockets", "192.168.2.100:5080");" has parse error. I can't see why the IP is correct and if I change it to localhost/127.0.0.1 I get the same error. What can be the problem in this line? Everywere I checked it is just the same. Third, when trying to run WeSIP with WeSIP/bin/startup.sh I get the following Java exceptions: -Dlog4j.configuration=file:/usr/local/src/wesip/conf/log4j.properties org.apache.catalina.startup.Bootstrap -config /usr/local/src/wesip/conf/server.xml start Catalina.start using /usr/local/src/wesip/conf/server.xml: java.lang.IllegalArgumentException: This container is not a StandardHost java.lang.IllegalArgumentException: This container is not a StandardHost at org.apache.commons.digester.Digester.createSAXException(Digester.java:2792) at org.apache.commons.digester.Digester.createSAXException(Digester.java:2818) at org.apache.commons.digester.Digester.endElement(Digester.java:1070) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.endElement(AbstractSAXParser.java:633) at com.sun.org.apache.xerces.internal.parsers.AbstractXMLDocumentParser.emptyElement(AbstractXMLDocumentParser.java:221) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanStartElement(XMLDocumentFragmentScannerImpl.java:872) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(XMLDocumentFragmentScannerImpl.java:1693) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:368) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:834) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:764) at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:148) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1242) at org.apache.commons.digester.Digester.parse(Digester.java:1572) at org.apache.catalina.startup.Catalina.start(Catalina.java:428) at org.apache.catalina.startup.Catalina.execute(Catalina.java:358) at org.apache.catalina.startup.Catalina.process(Catalina.java:129) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:156) Please advise.

Hi Raphael, What are the advantages of binrpcctrl and sipctrl over the unixsockctrl? Has enough testing done on them? We are currently using SEMS with SER0.9.6 (with unixsockctrl) and it is working OK for us. IF we move to the binrpcctrl or sipctrl would we get a better performance?
