[Serusers] How to send PSTN CALLs to a NATED PSTN GW?
by Alberto Cruz 16 Jul '06

16 Jul '06

Hi guys maybe this have been asked before. I have the following: * I have an ADSL Internet access with a public dynamic IP. * I have a broadband router in order to share the Internet access using NAT. * I have a VoIP GW that supports register connected behind the NAT. When the GW registers itself SER knows its source IP and UDP port. Does anybody knows how to forward the PSTN calls to the GW when it is behind a NAT? Regards Alberto Cruz

[Users] REFER To: (how to handle in OpenSER)
by Frogger 16 Jul '06

16 Jul '06

I am trying to handle the REFER method for call-transfer and I need some assistance. What is the openser.cfg structure to handle a refer from ua1 to ua2 so that ua2 can call ua3? Basically, I am trying to establish a new INVITE with the REFER-To for ua2 calling ua3. Also, I need to clean up the initial transaction between ua1 and ua2. BTW, I read the rfc on REFER and I have a good sense of whats supposed to happen but I lack the mechanics to make it so. All the guidance will be very helpful. Thanks, F __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

That's actually a deep architectural observation with which I can only wholeheartly agree. -jiri At 21:40 13/07/2006, Richard Z wrote: >Hi, > >All SIP ALGs are broken one way or another.

Hi Largo, the replicated REGISTER should not be authenticated by the other server as the request was already authenticate by it. You should do something like this: if (src==other server) { save(); } else { do auth save() replicate() } regards, Bogdan Largo wrote: > Hi Bogdan, > > > I got a problem regarding the t_replicate function. > I got an openser server working as a loadbalancer with (DISPATCHER); > let´s call it OPENSER-0. > He is dispatching to 2 openser servers ; let s call them OPENSER-1 and > OPENSER-2. > > Everything works fine, but if one analyses the packets and the error > logs closely, we observed the following: > - Every day there is only one of the servers who is correctly woking , > the second one sends always a "404 Not Found". > - There are problems by replicating: OPENSER-1 as example, receives a > "401 Unauthorized" back from the OPENSER-2 > - And in the syslog files , I see this: > /Jul 14 13:58:56 OPENSER-2 /usr/local/sbin/openser[30005]: PG[224] > str2valp got string f3415bc4b2e66989142d134d0d33be91 > Jul 14 13:58:56 OPENSER-2 /usr/local/sbin/openser[30005]: PG[224] > str2valp got string Jul 14 13:58:56 OPENSER-2 > /usr/local/sbin/openser[30005]: SRC not 23: Replicating... > / > - Here are scarps from the openser.cfg Files of the 3 servers (only > important configs) > > -------------------------------------------------------- > #OPENSER-0 (DISPATCHER) > > listen=192.168.1.21 > alias="openser_0.XXX.com" > > ... > > route{ > # log all incomming requests > xlog("L_INFO", "RECV: <$rm> signal from ip <$si> r-uri <$ru> > from <$fu> to <$tu> contact <$ct>\n"); > > if (!mf_process_maxfwd_header("10")) { > sl_send_reply("483","Too Many Hops"); > exit; > }; > > if (msg:len >= 2048 ) { > sl_send_reply("513", "Message too big"); > exit; > }; > > ds_select_dst("2", "0"); > forward(uri:host, uri:port); > } > > > > > -------------------------------------------------------- > -------------------------------------------------------- > #OPENSER-1 > > listen=0.0.0.0 > alias="openser_0.XXX.com" > > ... > > if (method=="REGISTER") { > > # Uncomment this if you want to use digest > authentication > if > (!www_authorize("sip-main.kh.emindgroup.com", "subscriber")) { > > www_challenge("sip-main.kh.emindgroup.com", "0"); > exit; > }; > > if(!save("location")) > { > sl_reply_error(); > } > else if( !src_ip==ip-of-openser-server-2 ) > { > xlog("L_INFO", "SRC not > openser-server-4: Replicating..."); > #if(t_newtran()) > #{ > # xlog("L_INFO", "NewTran: > Replicating..."); > t_replicate("ip-of-openser-server-2", > "5060"); > #} > } > else > { > xlog("L_INFO", "SRC 24: do nothing..."); > } > exit; > }; > > > -------------------------------------------------------- > -------------------------------------------------------- > #OPENSER-2 > > listen=0.0.0.0 > alias="openser_0.XXX.com" > > ... > > if (method=="REGISTER") > { > # Uncomment this if you want to use digest > authenticatio > n > if > (!www_authorize("sip-main.kh.emindgroup.com", "subscr > iber")) { > > www_challenge("sip-main.kh.emindgroup.com", "0") > ; > exit; > }; > > if(!save("location")) > { > sl_reply_error(); > } > else if( !src_ip==^ ) > { > xlog("L_INFO", "SRC not > openser-server-1: Replicating..."); > #if(t_newtran()) > #{ > #xlog("L_INFO", "NewTran: > Replicating..."); > t_replicate("ip-of-openser-server-1", > "5060"); > #} > } > else > { > xlog("L_INFO", "SRC 23: do nothing..."); > > } > exit; > }; > > lookup("aliases"); > if (!uri==myself) { > append_hf("P-hint: outbound alias\r\n"); > route(1); > }; > > # native SIP destinations are handled using our USRLOC DB > if (!lookup("location")) { > sl_send_reply("404", "Not Found"); > exit; > }; > append_hf("P-hint: usrloc applied\r\n"); > }; > > route(1); > } > > -------------------------------------------------------------------------- > > > Thanks in advance > Largo !

Hi Largo, for questions related to OpenSER, the right mailing list is users(a)openser.org .

[Users] database version override
by Mike Williams 14 Jul '06

14 Jul '06

All, I am adding a second system to my setup, the first is version 1.0.1, and the second is 1.1. I would like to use both at the same time, to be sure that my new version functions properly, and so I can keep services running as I transition. However, I need a way to override the version table; OpenSER 1.1 detects that it is an old version. I know I need to add the new columns, but I will still need to force OpenSER to use it. Does anyone know how to do this? ---Mike
