[Serusers] pstn gateway
by jorain 07 Dec '06

07 Dec '06

Hi all, I have a PSTN gateway (IP:123.456.78.90), when I route to it, there is no audio between PSTN and UA. I found that the PSTN gateway IP is different from the media IP, which is specified inside the SDP Connection Information (c) : IN IP4 xxx.xxx.xxx.xxx My RTPProxy is working and tested before. Please help. Thanks Regards, jorain

[Serusers] load balancing amongst servers
by Zeeshan Sajid 07 Dec '06

07 Dec '06

First of all thanks for the response and support ... really appreciate that ... This time the problem is alittle more complex now coming to the point I really need to know how can i do load balancing for a situation like [SER1] DIALER ----------------> [SER2] --------> PSTN [SER3] I have 3 SER servers and i want some kind of load balancing amongst them. I have been trying to make SER work behind a load balancer but that seriously involves mangling with some headers. So, is there any clean way to get this done ... Please help me in this as i am pretty struck at this point... regards, Zeeshan. --------------------------------- Cheap Talk? Check out Yahoo! Messenger's low PC-to-Phone call rates.

[Users] openser.org web site: new look
by Daniel-Constantin Mierla 07 Dec '06

07 Dec '06

Hello, just to let you know that a new template which is more in harmony with the OpenSER logo has been deployed on the web site. Anyone who considers that can improve the design and make user's experience better, please send an email to devel(a)openser.org or team(a)openser.org. The site uses the open source cms mambo/joomla engine. The OpenSER logo should have replaced old variants, and has been posted in relevant new places (e.g., dokuwiki). See: http://www.openser.org If you want to get the OpenSER logo, there are two variants available on the site, with white background and transparent: http://www.openser.org/images/openser-logo.jpg http://www.openser.org/images/openser-logo-transparent.png Cheers, Daniel

[Users] avpops multi db query
by vallimamod abdullah 07 Dec '06

07 Dec '06

Hello list, For my call routing algorithm, I need to query different databases to retrieve the destination of an outgoing call. From what I have understood, I can specify only one db url in the avpops module to use with avp_db_query(). Is there a (simple) way to make queries in different databases with openser ? Thanks. -- Regards, -vma .

[Users] ACK and re-INVITE ordering
by Jerome Martin 07 Dec '06

07 Dec '06

Hello everyone, I found many references in serdev, openser users, etc. MLs to the issue at hand, but only came up with diverging opinions and no solution whatsoever. The issue appears in case of a UA sending a re-INVITE inside of an established dialog. Depending on your configuration file, version, network conditions, there is NO guarantee that this re-INVITE will be sent to (I'm not even talking about reaching) the next hop (typically a PSTN gateway) AFTER the ACK to the first INVITE of the dialog. I perfectly understand why (openser being transaction and not dialog statefull being the only reason that really matters, given the fact that INVITE and ACK are separate transactions, often handled by separate openser processes) it is this way. However, it seems that several gateways are not handling this well at all, and just drop the transaction typically sending a "500 Server internal error". I've read reports about cisco AS5300, Asterisk, and I am myself experiencing this with an Andiocodes Mediant 2000 gateway. In my case, the issue is there 99% of the time. I know I could profile a bit my config file to ensure ACKs are processed faster than INVITEs (which propably is already the case), but this is hardly a workaround. I got tempted to even call an external "timer" via exec_msg when detecting a re-INVITE (if it is an INVITE, has a to_tag and is loose routed), but come on, I'm sure we can do better than this ! So no matter what the RFCs say or mean to say, no matter how long we argue about this, the facts are : - gateways often don't stand this ordering issue - many iPBXs are using reINVITEs for several call features - the only way to solve this is to be dialog statefull, at least for ACKs and INVITES So my conclusion is : I'm going to code an ugly little hack - using an external database and avpops - so that ACKs are logged per Cseq+callid, and when reinvites are detected, relay will be delayed until the last ACK is logged as sent. What do you think ? Is there a way to use the dialog module to optimize this (flagging the SIP headers themselves instead of an external DB) ? Best Regards, Jerome Martin

Re: [Serusers] Call transfer
by jorain 07 Dec '06

07 Dec '06

Hi all, Is it deal with the ctd.sh script? Configure inside loose_route()? I can get the REFER message but no responses (202 Accepted and NOTIFY) to it. So I send reply 202 inside loose_route if method=REFER. After that, inside ethereal, I can see the code 202 response to REFER. However, It send REFER again and after a while 408 TIMEOUT. This is what i configured: if(loose_route()){ if(method=="BYE"){ setflag(1); setflag(2); }; if(method=="REFER"){ sl_send_reply("202","Accepted"); }; t_relay(); break; }; Please help.

Re: [Users] using the acc module
by Daniel Burge 06 Dec '06

Hi Nick, Here is how the top of my cfg looks now: debug=3 # debug level (cmd line: -dddddddddd) fork=no log_stderror=no # (cmd line: -E) log_facility=LOG_LOCAL6 I also added this line to syslog.conf: # Save openser accounting logs to openseracc.log local6.* -/var/log/openseracc.log Previously there was information written to /var/log/openser.log which contained mostly things that happened on start up. It seems that openser logs to that file by default even if there is no log_facility set in the cfg file. Now all those messages are instead being put in /var/log/openseracc.log. However, still there are no accounting messages logged. Any ideas? Thanks again, Daniel nick wrote: > Daniel Burge wrote: >> Hello, >> >> I'm trying to configure the accounting module to log messages to >> syslog by following the instructions here: >> >> http://www.openser.org/docs/modules/1.1.x/acc.html >> >> I've included these lines where appropriate according to the example >> on that page.

[Users] using the acc module
by Daniel Burge 06 Dec '06

06 Dec '06

Hello, I'm trying to configure the accounting module to log messages to syslog by following the instructions here: http://www.openser.org/docs/modules/1.1.x/acc.html I've included these lines where appropriate according to the example on that page. The meaningful parts of the code are as follows: loadmodule "/usr/local/lib64/openser/modules/acc.so" modparam("acc", "log_level", 1) modparam("acc", "log_flag", 1) route { if (method=="INVITE" || method=="BYE" || method=="CANCEL") { setflag(1); /* set for accounting (the same value as in log_flag!) } } However this is not causing any information to be logged to syslog. Any idea? Thanks in advance, Daniel
