[Users] MAJOR FIXUP: avp access in reply route
by Bogdan-Andrei Iancu 12 Feb '07

12 Feb '07

Hi everybody, The ability of accessing/processing AVPs in reply route was a long debated and wanted functionality. Finally, OpenSER 1.2.x fixes this. The new code allows two types of behaviours: - use per message AVPs in reply route - no special synchronization is needed, but there is no persistence outside reply route. - use per transaction AVPS in reply route (as in failure route). the above behaviours apply to the reply routes triggered by TM. You can control this via the new TM parameter "onreply_avp_mode": http://www.openser.org/docs/modules/1.2.x/tm.html#AEN303 in default reply route only per message AVPs will be available. regards, bogdan

[Users] invitation: SER User and Developer Meeting, collocated with the IETF, in Prague, March
by Jiri Kuthan 12 Feb '07

12 Feb '07

Ladies and gentlemen, boys and girls, be wholeheartly welcome to the SER user/developer meeting in Prague, March, colocated with the IETF meeting. For more information see http://www.iptel.org/ietf_meeting If interested in participation, just register yourself. Whereas this event is coming from the SER crowd, the content is going to be primarily technical and openser all in all draws greatly from SER. I believe this can be most useful for users(a)openser.org as well. -jiri -- Jiri Kuthan http://iptel.org/~jiri/

[Users] MEDIAPROXY - Cannot detect inactive rtp sessions, any other BYE fix method?
by Dan-Cristian Bogos 12 Feb '07

12 Feb '07

Hi Guys, I know that this is not the support channel of mediaproxy, but just hoping that somebody from ag-projects is monitoring this list as well. I found out that, in my case, the SIP-BYE issue is still persistent even by using mediaproxy . If I will stop sending rtp through mediaproxy (eg by killing my client from task manager, or loosing the internet), mediaproxy will still find the session active, like nothing happened and therefore the bill will be inaquarate. I am using the version 1.7.2, and as read in the change log, 1.8.0 didn't change anything on this chapter. Is there any other solution or workarround available? Thxs, Dan

[Serusers] Patch for MySQL 5.0.19 and above in SER 0.9.x
by sip 12 Feb '07

12 Feb '07

I've attached a patch file for people to use (it really only adds 3 lines) to patch the my_con.c file in the mysql module for SER 0.9.x I've tested it for a week with inactivity, restarts of mysql, etc, and it holds up rather well, but of course I would be remiss if I didn't add a 'use at your own risk' disclaimer. ;) The basic problem is that, after MySQL 5.0.3, they changed the default behaviour of the mysql connection socket to NOT reconnect in the case of a timeout or a restart of the server. If you had SER up and running for a while, or if there were a glitch with your mysql, the connection would time out/disconnect, and SER would no longer be able to hit the database (requiring a restart of SER). The MySQL coders added an option to enable the reconnect ability of the mysql connection, but it didn't work until 5.0.19. SO... if you're using mysql 5.0.19 or above with SER 0.9.x (there may only be 3 of us doing this ;) ), here's a patch file for you to apply to my_con.c in your modules/mysql directory. I'd recommend backing up your my_con.c file before patching. N.

[Users] A better way to count the length of a variable
by Tavis P 12 Feb '07

I'm trying to find a fast way to count the length of a variable (and detect when the length exceeds a certain value) All i've come up with so far is a regex, does anyone know of a faster/better way to do this? Heres my current approach: !avp_check("$ci", "re/^.{1,128}$/g") tavis

[Serusers] Problems with Rtpproxy traffic balancing in SER 0.10.x
by Angelo Taddeo 12 Feb '07

12 Feb '07

I'm using ser 0.10.x ( CVS version). About rtpproxy traffic balancing, I don't know where I have to put rtpproxy IP address and where I have to set $node variable value. How does SER obtain rtpproxy IP address ? What the relation between rtpproxy IP address and N0, N1.....etc ? What parameters have I to put in force_rtp_proxy() function? Only rtpproxy IP address? In my framework happens : when SER receives INVITE Request and 200 OK it rewrites the body of SIP message (SDP). The problem is that it doesn't put in connection information (c) rtpproxy IP address; it puts its IP address. So clients send their RTP packet to SER instead to rtpproxy. How I can force SER to rewrite correctly SDP so that clients receive rtpproxy IP address in INVITE and 200 OK SIP message? Thanks in advance Alekos --------------------------------- L'email della prossima generazione? Puoi averla con la nuova Yahoo! Mail
