[Users] rtpproxy - fax
by Hakan YASTI 07 Jul '06

07 Jul '06

Dear All, I use openser 1.0.1 and use rtp proxy for some cases other than nat option. At voice calls I do not have any problem. But When I try to send fax,it is unsuccesful. I investigated the logs and saw that, after the reinvites ( to take the session from g729 to G711u bypass mode ), the last OK message's SDP that is sending from openser to user agent is not correct.Etheral logs are attached. Is it a bug of rtpproxy ? Any suggestion. Best Regards, Hakan.

[Users] Performance troubleshooting
by Dimo 04 Jul '06

04 Jul '06

Hi, I am having performance issues with openser running on Fedora. Here is the scenario: I have a openser which is sending calls to two asterisks, doing radius accounting and local syslog accounting, the database for user location is a local MySQL and the asterisks are load-balanced through dispatcher. i have modules: loadmodule "/usr/local/lib/openser/modules/mysql.so" loadmodule "/usr/local/lib/openser/modules/sl.so" loadmodule "/usr/local/lib/openser/modules/tm.so" loadmodule "/usr/local/lib/openser/modules/rr.so" loadmodule "/usr/local/lib/openser/modules/maxfwd.so" loadmodule "/usr/local/lib/openser/modules/usrloc.so" loadmodule "/usr/local/lib/openser/modules/registrar.so" loadmodule "/usr/local/lib/openser/modules/nathelper.so" loadmodule "/usr/local/lib/openser/modules/textops.so" loadmodule "/usr/local/lib/openser/modules/xlog.so" loadmodule "/usr/local/lib/openser/modules/avpops.so" loadmodule "/usr/local/lib/openser/modules/avp_radius.so" loadmodule "/usr/local/lib/openser/modules/acc.so" loadmodule "/usr/local/lib/openser/modules/options.so" loadmodule "/usr/local/lib/openser/modules/uri_db.so" loadmodule "/usr/local/lib/openser/modules/auth.so" loadmodule "/usr/local/lib/openser/modules/auth_db.so" loadmodule "/usr/local/lib/openser/modules/auth_radius.so" loadmodule "/usr/local/lib/openser/modules/dispatcher.so" Now the problem is that if i use sipp to send INVITE with 10-20 call attempts per seccond at one time ser just timeouts without answering for 1-2 seconds and sipp has to retransmit the packets. The timeout which sipp waits is 500ms so it should be enough. I have something like on 500 call attempts i get 700 retransmits. I will start stripping the config to troubleshoot but i was wondering if you can give me some idea what the problem might be or some good advice on troubleshooting, where should i look, and if you have any bes practices to recommend. BR, Dimitar

Re: [Serusers] How do I get rid of npdi=yes?
by Jiri Kuthan 01 Jul '06

I don't think that the problem in URI is presence of npdi. The problem is IMO that it is a SIP URDI without a domain -- I don't really see to where I would be able to send such a URI. -jiri At 19:53 23/06/2006, John Clements wrote: >I've looked around and have found one or two other posts asking about >this, but I have never seen an answer.

[Serusers] Logging weirdness with Aliases.
by sip 01 Jul '06

01 Jul '06

Okay... help me visualise something. Now, as far as I can tell, SER is doing exactly what it's supposed to be doing, but I can't figure out how to get it to do something different. I have an accounting section (my log flag is 1) that looks like this: if((method=="INVITE" && !has_totag()) || method=="BYE") { setflag(1); }; Basic, simple logging section. But when someone calls through from a DID to an alias in the aliases table, it of course logs the sip_to as the alias. Fine, I thought. I'll just add a lookup("aliases") before the setflag and all will be well, right? No. Then it doesn't seem to log anything at ALL. So what I'm trying to figure out is how to get SER to log a call coming into an alias as a call to the user who's aliased. I.e. a call is coming in from 1010(a)remote.proxy.com to 9999(a)proxy.com (which is really an alias to user 1234(a)proxy.com). Right now, SER is logging in the acc tables that the call went to sip:9999@proxy.com. I want to have it log that the call went to 1234(a)proxy.com and NOT that it went to the alias. This: if((method=="INVITE" && !has_totag()) || method=="BYE") { lookup("aliases"); setflag(1); }; gets me nothing at all. Ideas, anyone? I'm stumped. I'm sure it's something drastically simple that I'm just not getting. N.

[Serusers] SER statistics
by Adrian A 30 Jun '06

30 Jun '06

Hi, I'm looking for a way to extract statistics from SER such as registrations or invites per second. I was thinking I could either log all of these to a file using xlog and then parse it, but it's not going to be pretty. Does anyone have any suggestions? Thanks.

[Users] Radius accounting on debian
by Jeff Williams 30 Jun '06

30 Jun '06

I have openser-tls and openser-tls-radius-modules install on a debian sarge box, but the radius options for the acc module seem not to work. galileo:~# /etc/init.d/openser restart There are errors in the configuration file. Please fix them first. Also make sure you have installed the debian packages that provide the additional modules that your configuration requires. cpl, jabber, mysql, postgres and radius are in separate packages. 0(14929) set_mod_param_regex: parameter <radius_config> not found in module <acc> 0(14929) parse error (34,20-21): Can't set module parameter 0(14929) set_mod_param_regex: parameter <radius_flag> not found in module <acc> 0(14929) parse error (35,19-20): Can't set module parameter 0(14929) set_mod_param_regex: parameter <radius_missed_flag> not found in module <acc> 0(14929) parse error (36,19-20): Can't set module parameter ERROR: bad config file (3 errors) Is radius support for the acc module not included in these packages? Do I need to grap the source? Jeff

[Users] Cisco radius auth
by Jeff Williams 30 Jun '06

30 Jun '06

Is there any way to get openser to do radius auth using attribute from the Cisco VSA Voice Implementation Guide <http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_programming…>? i.e. something like: Access-Request NAS-IP-Address = 203.56.98.120 NAS-Port-Type = Async User-Name = "62186234" cisco-h323-conf-id = "h323-conf-id=89437006 E20011DA B677BBCA D2EBCDD5" Called-Station-Id = "0011553334112401" Calling-Station-Id = "0295731743" User-Password = "<145>;<22><242>$<251><243>)u<183>h<225>y<173><150><193>" I would like to get openser to authenticate against an existing billing system if possible.
