[Serusers] Immediately update aliases table
by Nick Hoffman 16 Apr '06

16 Apr '06

Hi guys. Even when using db_mode=2 for usrloc: modparam("usrloc", "db_mode", 2) there's still some time between adding an alias and the alias being written to the aliases table. Is there any way to immediately update the aliases table? Are there any reasons to not do this? Thanks! -- Nick e: nick.hoffman(a)altcall.com p: +61 7 5591 3588 f: +61 7 5591 6588 If you receive this email by mistake, please notify us and do not make any use of the email.

[Serusers] SER & MySQL Cluster v5 - no caching!
by Kerker Staffan 16 Apr '06

16 Apr '06

hi can anyone give me a hint here of what's true and what's not? i'm planning to use a multiple SIP proxy installation sharing location database using a MySQL cluster. i planned to use SER as proxy, but to me it seems like the SER caches location DB instead of reading from the MySQL database? in a multiple proxy installation, every proxy may recieve an incomming REGISTER and store that registration to the shared mysql database. but if the other proxies caches the location database instead of reading from the cluster, they will never be aware of registrations not made by them self... so this makes the SER no good for my installation. is this true or just bad rumours? best regards, /Staffan Staffan Kerker Saab Communications, Växjö m. staffan.kerker(a)saabgroup.com

[Serusers] Not found in usrloc
by davor jovanovic 16 Apr '06

16 Apr '06

Hi all, I have a problem with using aliases when user doesn't answer the call (408, request timeout). for this I'm using failure_route[1]. After 20sec when user doesn't answer the call, call comes in failure_route and it is recognizes as 408, but when I want to rewrite URI with alias "884" I get "Not found in usrloc", but as you can see from the output of "serctl ul show" user is in both tables (location and aliases). Can somebody help because I don't know what I'm doing wrong. Thanks a lot davor ******************************************* failure_route[1]{ if(t_check_status("408")){ log("LOG:entered failure route 1 on code 408\n"); lookup("aliases"); rewritehostport("161.53.2.235:5060"); t_relay(); } } ******************************************** 1(22439) ->>>>>>>>> T_code=180, new_code=408 1(22439) DEBUG: t_check: msg id=2 global id=2 T start=0x40460708 1(22439) DEBUG: t_check: T already found! 1(22439) DEBUG:t_check_status: checked status is <408> 1(22439) LOG:entered failure route 1 on code 408 1(22439) lookup(): 'djovanovic' Not found in usrloc 1(22439) ERROR: t_forward_nonack: no branched for forwarding 1(22439) ERROR: w_t_relay (failure mode): forwarding failed ******************************************** serctl ul show domain: 'location' aor : 'djovanovic' ~~~Contact(0x404604a8)~~~ domain : 'location' aor : 'djovanovic' Contact : 'sip:djovanovic@161.53.0.77:5060' Expires : 429 q : Call-ID : '40C79AFEA5C644ADB6FEA320F247C793(a)sipgw.srce.hr' CSeq : 52664 ...Record(0x4045e238)... domain: 'aliases' aor : '884' ~~~Contact(0x4045e298)~~~ domain : 'aliases' aor : '884' Contact : 'sip:djovanovic@sipgw.srce.hr' Expires : Permanent q : 1 Call-ID : 'The-Answer-To-The-Ultimate-Question-Of-Life-Universe-And-Everything'

[Serusers] Problems with PSTN and REINVITE
by sip 14 Apr '06

14 Apr '06

I appear to be having problems with REINVITE messages lately (I may have simply never before received them and there was ALWAYS a problem... I don't know for certain). When I dial certain numbers -- so far it's only been numbers over the PSTN going through likely Asterisk gateways, everything goes fine UNLESS I get a reinvite. At that point, audio stops (though the stream appears to remain open). My UA will send an INVITE, I'll hear the answer on the other side for about a second -- audio will be fine... then a REINVITE is sent from the remote side and audio stops completely while the stream remains active. Has anyone run across this before? Is there something special I should be looking for in my ser.cfg to handle REINVITES as they bounce along? Is it a problem, perhaps, with a swallowed ACK somewhere? I'm hoping someone can give me a clue or two to point me in the right direction. Thanks, N.

FW: [Serusers] NOTIFY Packet loss with big sip message
by Gourav Jain 14 Apr '06

14 Apr '06

Hi Vaclav, Thanks for the response.. But the problem here is my ISP blocks the TCP requests. I have to sent it over UDP only. And also over local network this message is getting delivered does SER operated on the message and converts it to TCP, is it so then how can we disable that. Gourav Jain -----Original Message----- From: Vaclav Kubart [mailto:vaclav.kubart@iptel.org] Sent: Friday, April 14, 2006 4:43 PM To: Gourav Jain Cc: 'serusers(a)lists.iptel.org' Subject: Re: [Serusers] NOTIFY Packet loss with bit message Hi, you should use TCP instead of UDP in the case of big messages like presence notifications... I think that something about this is written in SIP RFC (3261).

Hi Jayesh, I have a problem similar at yours, could you help me ? I need to load data from acc table using avp_db_load. I setup my cfg file in this way: modparam("avpops", "db_scheme", "scheme0:username_col=username;value_col=sip_callid;table=acc") if (avp_db_load("$to", "$avp(s:sip_callid)/scheme0")) { xlog("L_INFO","Lettura OK"); }; But I have this error in the log: Apr 14 01:07:55 localhost /usr/sbin/openser[6799]: ERROR:avpops:parse_avp_db: unknow alias"avp(s:sip_callid)/scheme0" Apr 14 01:07:55 localhost /usr/sbin/openser[6799]: ERROR:avpops:fixup_db_avp: parse failed Apr 14 01:07:55 localhost /usr/sbin/openser[6799]: ERROR: fix_expr : fix_actions error Any thought? Thanks for help Davide ________________________________ Da: users-bounces(a)openser.org [mailto:users-bounces@openser.org] Per conto di Jayesh Nambiar Inviato: mercoledì 12 aprile 2006 0.06 A: openser Oggetto: [Users] avp_db_load problem Hi all, I was trying to do the following: Whenever a user presses *86 and then any number, first openser should check in the subscriber table, whether the value for features column is 1. (I've added an extra column features in the table subscriber with datatype int). If the value is 0, he should be replied with the message Forbidden. I tried doing the following: modparam("avpops","db_scheme", "scheme1:username_col=username;value_col=features;table=subscriber") if(uri=~"sip:\*86[0-9]*@") { log(1,"entered condition"); if(avp_db_load("$fU", "$avp(s:features)/$scheme1")) { log(1,"db load succeeded"); if(!avp_check("$avp(s:features)", "eq/1/g")) { sl_send_reply("403", "Forbidden"); exit; }; strip(3); log(1,"stripped"); avp_db_query("insert into usr_preferences values('', '$fU', '', 'callfwd', '', '$ruri', 'CURRENT_TIMESTAMP')"); sl_send_reply("200", "OK"); exit; }; }; But in the logs I only get "condition succeeded" which means it does not do the avp_db_load() properly. Can someone please help me in what should be the exact syntax to load it from the db and then check the value. thanks in advance, jayesh ________________________________ Jiyo cricket on Yahoo!
