[OpenSER-Users] New module - userblacklist
by Henning Westerholt 29 Feb '08

29 Feb '08

Hi, i just imported a new module, called 'userblacklist', into the svn trunk. To quote from the README: The userblacklist module allows OpenSER to handle blacklists on a per user basis. This information is stored in a database table, which is queried to decide if the number is blacklisted or not. An additional functionality that this module provides is the ability to handle global blacklists. This lists are loaded on startup into memory, thus providing a better performance then in the … [View More]

[OpenSER-Users] OpenSER 1.2.2 and 302 Moved, funny log issue?
by Tobias Lindgren 28 Feb '08

28 Feb '08

Hi there, I was trying to do this in OpenSER 1.2.2: failure_route[1] { if (t_check_status("302")){ xlog("L_ERR", "302 source ip address is $si"); if (src_ip == 192.168.5.1) { # Do something }; }; }; But the proxy sending the 302 (192.168.5.1) is not the one who ends up in my logs, instead my sip-server (192.168.1.1) who initiated the call ends up in the log. "302 source ip address is 192.168.1.1". Have I understood the "$si" psuedo variable wrong? Can I find the correct source … [View More]

[OpenSER-Users] Building openser-1.3.0 on Debian stable
by Sajith T S 28 Feb '08

When trying to build openser-1.3.0-tls (tarball from openser.org) on Debian stable, "make all" throws this error: if [ "no" = "yes" ]; then \ cd utils/db_berkeley; make all ; \ fi ; \ /bin/sh: -c: line 4: syntax error: unexpected end of file make: *** [utils] Error 2 The last backslash (after "fi ;") is the problem (line #521 in the top-level Makefile). This is in SVN trunk and 1.3 branch too as far as I can tell. Thanks, Sajith. -… [View More]

Thank you for your replies. The sipwise code did have an append branch and a branch route that dropped local branches. -- zahid -----Original Message----- From: "Andreas Granig" <agranig(a)sipwise.com> To: "Bogdan-Andrei Iancu" <bogdan(a)voice-system.ro> Cc: "Zahid Mehmood" <zm23(a)columbia.edu>; "users(a)lists.openser.org" <users(a)lists.openser.org> Sent: 2/28/08 6:32 AM Subject: Re: [OpenSER-Users] OpenSER 1.2.2 and 302 Moved, funny log issue? Hi, Puh, it's … [View More]been a while since I wrote that, so let me think :) As far as I remember, the idea was to extract the first branch and push it into R-URI, then jump somewhere into the route sections where quite some R-URI manipulation and checking is done (and most of the functions can only operate on r-uri, so...)... after that, the ruri is again appended as branch before sending it out. Only problem is that you can only use one destination. Bogdan, what exactly do you mean by "if it does append_branch somewhere later, it will just duplicate a branch"?

Re: [OpenSER-Users] asterisk load balance dispatcher
by Daniel-Constantin Mierla 28 Feb '08

28 Feb '08

Hello, I believe your problem is related nat traversal. Do you do port forwarding on the firewall? As a tip, you should do record routing on openser. To troubleshoot, watch the sip traffic on your network and on the firewall box -- see whether messages are going caller -- asterisk all the time or they are blocked by firewall.

[OpenSER-Users] What is "timezone" field in "subscriber" table for?
by Iñaki Baz Castillo 28 Feb '08

28 Feb '08

Hi, "subscriber" table has a column "timezone". While it could be useful for CDR purposes and so, I find no relationship with OpenSer itself of its modules. Why does this column exist by default in subscriber table? Thanks. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

Re: [OpenSER-Users] What is "timezone" field in "subscriber" table for?
by Bogdan-Andrei Iancu 28 Feb '08

28 Feb '08

Hi Jonathan, More or less this is the whole idea - many openser admins configures a different additional set of fields in the subscriber table, based on the needs of some provisioning tools. Of course, we cannot find a common set for this extra (non-openser) fields, so the most clear way to do it is to keep in the openser default DB struct only the fields that are used by openser. Then, anybody may "customize" the tables, based on his particular needs, without conflicting with the "… [View More]
