[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.

[Users] openser as b2bua

The openser website clearly states that OpenSER is not a B2BUA. Is there a particular architectural limitation that would prevent a module from implementing a B2BUA within OpenSER? Cheers, M

[Users] pseudovariables in rewriteuser() - OpenSER 1.1.x
by Edoardo Serra 18 May '07

18 May '07

Hi all, I have the need to call rewriteuser() with a pseudovariable. My need is to rewrite the user with the content of an extra header I put in the SIP packet coming from a PSTN gateway I tried with rewriteuser("$hdr(X-DNID)"); but it doesn't replace the string with the ocntent of the pseudovariable. Any idea ? Tnx in advance Edoardo Serra WeBRainstorm S.r.l.

[Users] using of myself Core Values
by Victor Gamov 18 May '07

hi is it possible to do following in config if ( $avp(s:var_name) != myself ) { # do something } var_name is AVP looking like "192.168.0.1" If not -- how I can check that $avp(s:var_name) is not one of my IP-address (without using DOMAIN or other module but by core only) ? Thanks! -- CU, Victor Gamov

I've done the packet dump on both ends, on a box running x-lite (with the windows-firewall disabled) and on the proxy-host. Both show the same source/destination ip-adresses and ports, so I assume there cannot be any kind of ALG. However, there is some packet filter (not doing NAT) between the box and the proxy, maybe x-lite does some firewall-detection on startup and uses the wrong port-number in the via header intentionally to enforce the use of an rtp-proxy? I'll do some tests on a box that isn't protected by a packet filter on Monday. > By default, x-lite binds to local port 5060, but you've some > non-standard ports in there. So my guess is either a non-standard > port setting in x-lite and NAT, or a faulty ALG on the NAT device. I don't have any special settings in X-Lite, ICE is disabled, "Use local IP address" is enabled. I've noticed that your version of x-lite uses UDP, mine seems to use TCP by default.

Hi Users, I'm trying to setup a mediaproxy 1.7.2 running with operser 1.2.0 on Fedora 6. I can see all service running up. But when I make a call, the SDP does not change the owner address in the INVITE to callee. Openser only report following error: May 18 09:25:51 localhost /sbin/openser[2808]: error: mediaproxy/sendMediaproxyCommand(): can't connect to MediaProxy Configure as attachment, can anyone help? Thanks in advance. Regards, Lesley
