[Freeswitch-dev] FreeSWITCH Weekly News and Notes
by Michael Collins 12 Feb '13

12 Feb '13

Hello all! News and notes are back after a brief hiatus last week. We (the FreeSWITCH team) were in Milwaukee last week and we appreciated being fed by the community. Thank you! We love this community. It seems the big news <http://freeswitch.org/node/435> last week came courtesy of our friend Kristian Kielhofner <http://blog.krisk.org/>. As reported in this blog post<http://blog.krisk.org/2013/02/packets-of-death.html>, Kristian ran into a rather unusual set of circumstances that resulted in Packets of Death for some Intel NICs. In addition to being Slashdotted<http://tech.slashdot.org/story/13/02/06/2024251/intel-gigabit-nic-packet-of…>, Kristian's research ended up being featured in a Wired.com story<http://www.wired.com/wiredenterprise/2013/02/packet-of-death/>. Don't forget to read Kristian's update post<http://blog.krisk.org/2013/02/packets-of-death-update.html> that includes information about Intel's response to the whole situation. This week things will start to return to normal with our weekly conference call <http://wiki.freeswitch.org/wiki/FS_weekly_2013_02_13>. We are going to spend a few weeks talking about various FreeSWITCH GUIs, starting with the CudaTel <http://www.cudatel.com>. For the past four years or so we've been building the CudaTel Communication Server and we'd like to show off some of the cool things it can do. We have two other news items. The first one has to do with mod_ha_cluster<http://wiki.freeswitch.org/wiki/Mod_ha_cluster>, which our very own Eliot Gable is building. Financial support for this open-source module will be done through FreeSWITCH Solutions<http://www.freeswitchsolutions.com/>. An interesting discussion can be found in this email thread<http://lists.freeswitch.org/pipermail/freeswitch-users/2013-February/092095…>. The other item comes from Ken Rice who has some updates on Jira and ZRTP. Check out his mailing list post<http://lists.freeswitch.org/pipermail/freeswitch-users/2013-February/092155…>for more information. Have a great week and we'll talk to you on Wednesday. -- Michael S Collins Twitter: @mercutioviz http://www.FreeSWITCH.org http://www.ClueCon.com http://www.OSTAG.org

[Freeswitch-dev] DTMF duration unit
by François Delawarde 05 Feb '13

05 Feb '13

Hi all, I don't clearly get what unit we should use in dtmf-duration parameters (core min-dtmf-duration / max-dtmf-duration and sofia dtmf-duration). The variable name and some parts of the code/wiki imply it's in milliseconds (for example in sofia.c, we can see a line saying profile->dtmf_duration = 100;). However, the default values in switch_types.h suggest the values should be based on timestamp like in RTP. Something like: minimum = 400 @ 8kHz => 50ms default = 2000 @ 8kHz => 250ms maximum = 192000 @ 8kHz => 24s If the later is the right one, should I change values when using WB codecs that are NOT sampling at 8kHz? Also, is the "unit" consistent across all endpoint modules? Thanks, François.

[Freeswitch-dev] [patch] build with the recent binutils (DSO link change)
by Jun Sun 02 Feb '13

02 Feb '13

When I tried to build against the latest 64bit amazon ec2 instance, I got the following error: ---- ... checking for tgetent in -lncurses... no checking for tgetent in -lcurses... no configure: error: libtermcap, libcurses or libncurses are required! ---- A little bit research shows there was a ld behavior change recently. See the link below. http://fedoraproject.org/wiki/UnderstandingDSOLinkChange The attached patch fixes the problem. I *believe* the patch should be safe to older systems, but someone would have check it out. Cheers. Jun
