[Freeswitch-dev] trailing white spaces in code cleanup suggestions and jira question
by Seven Du 09 Apr '12

09 Apr '12

Hi, Some code has trailing white spaces and I found it's a little hard to manage code locally and keep it up to date with the upstream. Would any interest in cleanup? I could help with 1) one big change that write a script to clean all and 2) change one file/module a time to be safe but takes more time. I understand you are all busy working on the 1.2 branch and maybe causing trouble when merging back and forth. Jira questions: 1) I found jira is not sending alerting email when I create or comment issues recently. 2) Some modules are missing such as mod_fsv and mod_rtmp, is it ok to report to FS-CORE if cannot find a matching entry on jira? Thanks. 7. -- About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn Sent with Sparrow (http://www.sparrowmailapp.com)

[Freeswitch-dev] Terminal Emulators
by Michael Collins 06 Apr '12

06 Apr '12

Hey folks, Today on the conference call we had a brief but passionate discussion about terminal emulators. I'm finding that more and more I'm using all of the "big 3" operating systems and that they each have their own quirks and peculiarities. I decided to start a wiki page on the topic: http://wiki.freeswitch.org/wiki/Terminal_emulators I have been spending more time than I really want to on a Windows laptop so I have been getting familiar with putty. I added some putty info to the wiki plus a few other tidbits. I would like to invite everyone to hop on and add whatever knowledge or tips & tricks that they've learned over the years. If you know of a good terminal program that you use then feel free to add it to the list. Thanks! -MC

[Freeswitch-dev] Requirements to get actual UUIDs?
by Michael Giagnocavo 06 Apr '12

06 Apr '12

Hello, Does anyone know what's required for APR to generate UUIDs? Currently, FreeSWTICH is generating sequential timestamp-like numbers instead of UUIDs. When configuring APR, I get this output: Checking for OS UUID Support... checking uuid.h usability... yes checking uuid.h presence... yes checking for uuid.h... yes checking for library containing uuid_create... no checking for library containing uuid_generate... -luuid checking for uuid_create... no checking for uuid_generate... yes checking for os uuid usability... no This is on CentOS 6.2. Installed packages: libuuid, libuuid-devel, e2fsprogs, e2fsprogs-devel, and util-linux-ng. What do I need to do to make APR pick up on this and generate proper UUIDs (that is, 128 bits of randomness)? -Michael

[Freeswitch-dev] mod_esf ignores client BYE
by Lesley Pervis 04 Apr '12

04 Apr '12

I've discovered a bug with multicast paging that affects phones (like Cisco/Linksys/Sipura) that listen for multicast session control packets to hang up. Sniffing on the FreeSWITCH shows that FreeSWITCH does not respond to caller BYE on hangup, but waits five minutes before timing out waiting for media. It then sends its own BYE and sends multicast session control packets. For those five minutes, mod_efs is stuck continuing in a for(;;) loop and phones that count on hearing the multicast session control packets stay in session. The problem is with FreeSWITCH not replying to client BYE. I don't think the problem is necessarily in mod_esf, but currently this is beyond my ability to troubleshoot further. If anyone has an intuition on how to proceed, please let me know. I've raised a bug report in JIRA and it's been auto-assigned, but I haven't seen an indication it's been acknowledged. The bug is here: http://jira.freeswitch.org/browse/FS-4067 I've attached pcap and logs to the bug report.

[Freeswitch-dev] ZRTP Code Now In Tree
by Michael Collins 02 Apr '12

02 Apr '12

Hello all! This isn't an announcement so much as an FYI. Phil Zimmermann has been working diligently with our very own power user Travis Cross (IRC: tc) on getting ZRTP into a truly useful state. The first big step on that journey has been taken: libzrtp code has been added to the git repository. Travis Cross reports that getting to this point was a serious amount of work, and for that we thank him and Phil both. We are all going to benefit from ZRTP when it is ready for use. The code is available for your perusal, however it is not quite ready for use at this time. We invite everyone to join us on the FreeSWITCH conference call this Wednesday (agenda here<http://wiki.freeswitch.org/wiki/FS_weekly_2012_04_04>). Travis will be discussing what has been done thus far and what remains to be done. This will dovetail nicely with AEP who will be discussing the Freedom Fone project on Wednesday also. -Michael
