[Users] editing header multiple times
by zm23 20 Jun '07

20 Jun '07

Hi all, I am having some issues with editing remote party header. I understand that changes are saved as a diff and are sent when packet goes on wire. In my current config rpid is edited when invite is received and it seems to work fine. There is one scenario where I need to edit rpid or remove rpid altogether before relaying it. "remove_hf" did not remove the header after it was edited earlier. Is there a way to do this? Thanks in advance for your help. -- Zahid

[Serusers] avp_radius - ser2.1 - Access Request Contents
by tzieleniewski 07 Jun '07

07 Jun '07

hi! When I invoke the radius_load_attrs() the message send to radius has the following shape: Thu Mar 8 10:50:46 2007 Packet-Type = Access-Request User-Name = "sip:hellboy@voip.rd.touk.pl" SER-Service-Type = Get-User-Attrs NAS-Port = 0 NAS-IP-Address = 127.0.0.1 the message doesn't contain any authentication data like password. so do I understand right that radius in such case should be configured in such a way to accept any message of the SER-Service-Type = Get-User-Attrs? Are still the avp loaded from radius prefixed or they are just put into the particular track and class? Could You please give me one example of the radius one avp record and the shape in which it will appear in ser after loading. Thank you in advance Best Tomasz

[Users] presence module and retransmissions
by Klaus Darilion 25 May '07

25 May '07

Hi! Does presence module handles PUBLISH/SUBSCRIBE stateful or stateless? Thus, how should retransmission be handled. Will they be detected by presence module or is it possible to wrap the handle_publish inside t_newtran()? regards klaus

[Users] Dropped calls with OpenSER 1.1.x and Asterisk >= 1.2.14
by Edoardo Serra 19 May '07

19 May '07

Hi guys, I'm having a problem about asterisk dropping calls received from OpenSER The problems was spotted at Asterisk users mailing lists http://lists.digium.com/pipermail/asterisk-users/2007-April/184875.html Asterisk complains about an ACK not received and drops the calls. It expects OpenSER to send an ACK back to its '200 OK' when the call is set up Is that a problem OpenSER should solve ??? Tnx in advance Regards Edoardo Serra WeBRainstorm S.r.l.

[Serusers] Capturing all messages for testing purposes
by POON Ben 11 May '07

11 May '07

Hi, I am setting up a testing environment with about 100 users. I would like to see who is online/registered, conversation times, protocols, etc. Basically I want to be able to capture all the messages for troubleshooting purposes, durability, compatibility, reliability, etc. Will the acc module do that for me, how do I set it up to capture the data? Thank you very much, Ben

[Users] XCAP-Lite problems
by Schumann Sebastian 09 May '07

09 May '07

Dear all, starting to build up OpenSER as presence server, I had no mentionable problems. Now, I tried to implement an Apache2 based XCAP server to store presence info, buddy lists etc. there. I have a problem setting up the XCAP-Lite server v0.9. Searching the web and the mailing list did not lead to a successful answer why the following happens: After setting up Apache2 with all required modules, virtual host etc. I try to use Eyebeam 1.5 to write the presrules and resource-list.xml to the database. This failes. I have successfully installed Apache2 with pear (+ extensions), php, mysql support. I created a virtual host with the following settings: NameVirtualHost * <VirtualHost *> <Location "/"> Dav On #necessary for PUT method </Location> ServerName 172.16.167.128 DocumentRoot /var/www/ #/var/www/xcap-root didn't work for GET as well, changed RewriteEngine On RewriteLog /var/log/apache2/rewrite.log RewriteLogLevel 2 RewriteRule /xcap-root/(.*) /xcap-root/index.php ProxyVia On </VirtualHost> I putted all files from XCAP-Lite archive in /var/www/xcap-root. After using PUT method through Eyebeam (change in contact list) I receive the 204 No content message. BUT: Not the database content is changed, the putted XML file overwrites index.php instead, which means, further requests fail. Does anybody know why the access to database does not work? Password etc. in config.php is ok. Thanks in advance. Best regards Sebastian PS: As I didn't find a mail address of the author of the program, I hope he is also subscribed to that list. There is probably an error in xcap-lib.php on line 766. I think there is a space between function and XCAPclient necessary.

[Users] 183 early media and NATed clients
by Jeff Williams 07 May '07

07 May '07

Guys, I'm wondering what solutions there are to this problem. We have some NATed clients making outgoing calls. The NAT traversal is done using mediaproxy and works fine. However, we have a problem with 183 responses and early media ringing sounds. The problem is that before the NATed client starts sending out RTP data, mediaproxy doesn't know which IP and port to send the RTP traffic to. Some of the NETed clients don't start sending out RTP traffic until the call is connected, therefore none of the early media (ringing sounds) reaches the user - making it sound like dead air. Any ideas? Jeff

[Users] rtpproxy CPU usage issue..
by Sajith T S 04 May '07

04 May '07

Hi, Have any of you folks seen an abnormal CPU usage issue with rtpprpxy? At times, "top" shows rtpproxy uses 100% CPU (sometimes 99%, sometimes even 101%!), and it stops responding to openser. I have to restart everything now. A small thread in Serdev list recommends upgrading rtpproxy to latest in CVS: http://lists.iptel.org/pipermail/serdev/2006-June/007459.html Mine was fairly old, so I upgraded, but without much progress. What really bugs is I don't know what triggers it. Backtraces suggest that this occurs in different places in rtpproxy, before and after upgrading. Before upgrade: (gdb) where #0 0xb7f49410 in ?? () #1 0xbffd6d88 in ?? () #2 0x00000076 in ?? () #3 0xbffd2410 in ?? () #4 0x4a8d9fd1 in sendto () from /lib/tls/libc.so.6 #5 0x0804ac0c in main (argc=7, argv=0xbffd6e14) at main.c:1467 After upgrade: (gdb) where #0 0xb7f0a410 in ?? () #1 0xbfcb0258 in ?? () #2 0xbfcadfc0 in ?? () #3 0xbfcab8e0 in ?? () #4 0x00bb8dd1 in recvfrom () from /lib/tls/libc.so.6 #5 0x0804a568 in main (argc=7, argv=0xbfcb02e4) at main.c:1364 Any clues? Is this a known problem and is there a patch or some sort ofworkaround? Is there anything I need to upgrade? (This is CentOS 4.4, FWIW) Anything that should be done in openser configuration? Thanks much in advance. - Sajith.
