[Users] A problem wiht openseradmin0.3--Add New Account Preference
by Lee Jacky 29 Apr '07

29 Apr '07

Hi,everyone,I am jacky.I use openser1.1+openseradmin0.3. Now I am troubled with a problem,and here is the detail: After I install the openseradmin, I add attribute Tel to the account_preferences_type,and then I click the link:Add New Account Preference. I fill the form like this: username:admin domain:voip.net attribute:Tel values:12456 Then I click the button:Create, and it redirect to a error page,whose content is as follows: ArgumentError in Voip account preferencesController#create wrong number of arguments (1 for 2) RAILS_ROOT: /usr/local/openseradmin-0.3/script/../config/..

Hi Gines, thanks for your support > Your servlet named "neo" is being executed and looks like it is > proxying but what from what I see in the packet it is proxying to > itself. Could you try to proxy to another address and see if this > still happens ? Aside, could you send me your configuration files and > your servlet code ? The serlvet code is the following protected void doInvite(SipServletRequest callerInvite) throws ServletException, IOException { //Get a proxy for this request Proxy callerProxy = callerInvite.getProxy(); System.out.println("doInvite within neos servlet: requestURI is " + callerInvite.getRequestURI() ); callerProxy.proxyTo(callerInvite.getRequestURI()); } This code causes the "no route" exception. The println above gives : doInvite within neos servlet: requestURI is sip:5002@192.168.1.11 where 5002 is the called SIP phone and 192.168.1.11 is the address of my OpenSER + WeSIP box (i.e. the managed SIP domain) Following your advice I have tried to change the proxyTo to a different address: SipURI dest = sipFactory.createSipURI("5002","192.168.1.16"); callerProxy.proxyTo(dest); It that case, the called phone (5002, IP address 192.168.1.16) gets the INVITE correctly. However, something puzzles me here: the serlvet is not supposed to know the IP address of the called phone. In my understanding, the AS processes the INVITE, then it must send it back to the proxy server which is supposed to forward it to the next hop, is that right ? Could you please give me an example of a doInvite which basically does nothing and which lets the INVITE be forwarded to the called party ?

[Users] Openser with Quintum voice gateway and an important load
by mailinglist-openser-users 27 Apr '07

27 Apr '07

Hi, Openser version: 1.2.0 We have 4 central Quintum CMS platform hosted in our computer room. We have several tens of Qintum voice gateway ( DX / AX / Call Relay ) on remote customer site. Our customer are mainly call centers so they generate a lot of small calls with an important number of call wich are never established ( around 50% ). The central platform is quite loaded, with around 600 simultaneous calls and around 20 new call per second. Up to now, we used H323 as the signalisation protocol. Now we are planning to migrate to SIP and use openser 1.2.0 for that. Does anybody already use openser with Quintum as voice gateway with so many calls ? I'd like to share experience with people using this kind of setup with this kind of load. There are no know problem between openser and Quintum SIP implementation ( we use firmware P104-12-16 ) ? Openser should be able to route all these call towards our 4 central gateway with LCR while as well sending radius accounting. Our main and backup SIP server are IBM X330 ( Bi-Pentium III 1266 Mhz with 2GB of memory ). Will it be enough to handle 600 simultaneous call and 20 new calls per seconds ? For radius accounting, we have 2 radius servers. It seems that when the first adius server is down, openser is trying 3 times the first radius server and then go to the second one but the children seems to be blocked during this time ( for example in debug mode, no more new call can be establised while radius accounting is not yet finished ). So should I start lots of children ( 20 or more ) so that if the first radius is down, openser will still be able to route new calls while some children are blocked for accounting reason ? As well I'm planning to use the "dialog" module, if this module largely increasing the load on openser ? Regards, Jerome. -- Jerome

[Users] How can I pass pseudovariables to functions?

Hello All! I have a question. If I declare variable like this: $var(ip_address) = "192.168.0.1"; I can't use this variable in functions like that one: revritehostport ($var(ip_address)); It leads me to the following message: omega1 ~ # /usr/local/sbin/openser -f /usr/local/etc/openser/openser_registrar.cfg -l 192.168.0.1 0(5723) parse error (316,25-37): syntax error 0(5723) parse error (316,37-38): bad argument, string expected ERROR: bad config file (2 errors) So the question is %subj%. -- With best regards!

Re: [Users] NAT ping best methods

Hi Jerome, Thanks for the quick reply. I had used Openser to send NAT ping to all the registered UAs, but how do you send an OPTIONS message from Openser to the UAs registered in the location table. Also does the UAs reply as 200OK to the OPTIONS message or is it only one way. Can you please explain a little more. Thanks a lot in advance. w/regards, Jayesh ----- Original Message ---- From: Jerome Martin <jmartin(a)longphone.fr> To: Jayesh Nambiar <voip_freak(a)yahoo.co.in> Cc: openser <users(a)openser.org> Sent: Friday, 27 April, 2007 6:13:31 PM Subject: Re: [Users] NAT ping best methods Hi, We are working with natted PAP2, and openser is sending keepalive (SIP OPTIONS).

[Users] NAT ping best methods
by Jayesh Nambiar 27 Apr '07

27 Apr '07

Hi, I am using Openser 1.2 and all the UAs that register to it are only PAP2 or SPAs. But all these UAs are on a private network. I tried using the NAT ping method from Openser to keep the NAT port open, but still sometimes the NAT port gets blocked by some NAT boxes. I tried keeping the interval as 25 seconds. So then I tried sending Keep Alive Notify messages from the UAs itself towards my Openser, but there I see a strange problem. The problem is like the device does not send the notify message from the same port which it registered from in the first place. So the port which is stored in the locaion table gets blocked and again the user is not able to receive calls. The user is able to receive calls only after it registers again but then again it is inconsistent. Has anyone worked with PAP2 and Openser and has got some best method to maintain the NAT ports open so that the user receive calls consistently. I also wanted to know what is more efficient, the UAs sending keep-alives or Openser sending NAT-ping? Thanks in advance, w/regards, Jayesh Add online presence to your web pages, find out how here - http://messenger.yahoo.com/addpresence.php
