mux with uuid_displace: soundfile to loud
by Dennis 29 Jun '09

29 Jun '09

hi, we want to use uuid_displace with mux to playback a soundfile to a bridged uuid, so that this uuid can hear the other side talk AND hear the soundfile (whispering). is there an option we can set, for defining the loudness level of the soundfile? in our tests the soundfile was way to loud, so that it was nearly impossible to hear the other side talk, while the soundfile was playing. we tried "uuid_displace uuid start /path/to/soundfile/soundfile.wav 0 mux 0.3", so that the loudness of soundfile only would be 30% - but this does not work. thanks & kind regards dennis

Myevents in outbound socket
by Nik Middleton 28 Jun '09

28 Jun '09

Hi Guys, I've almost got my c++ outbound socket control prog running, however even though the filter works, it would be truly great to just subscribe to myevents as even with the filter in place I get lots of channel Execute and complete events which I don't really need. Problem is, is that mod_VMD isn't included in those events, even though it is channel specific. Is there any chance that this will be included? If not, can someone point me to where myevents is defined and I'll have a go at it myself. Regards,

Confused with event content lengths
by Nik Middleton 28 Jun '09

28 Jun '09

Hi Guys, I'm trying to parse events in C++ for an outbound socket. The docs are a little contradictory, so I wonder if someone could help me out. As I understand it and event is terminated with double LF's (\n\n) However if there is a Content-Length header the wiki very confusingly says 'Content-Length is the length of the event beginning AFTER the very next LF only line ("\n") and inclusive the trailing LF/LF pair ("\n\n")' BUT the example says it's after the \n\n in the header!! Which is it? In addition, it also looks like the event body is also terminated by a \n\n. If this is the case, why do I care about content length value, can't I simply read until I get the termination sequence? Regards,

Hi, Although its obvious but just asking for confirmation :) Is bypass media mode in FS is fairly stateful. If it in huge network so its cdr(billing) is relaiable ? -- Muhammad Danish Moosa

att_xfer w/uuid
by Matthew Fong 28 Jun '09

28 Jun '09

I'm trying to use xml_rpc to initiate an att_xfer on channel A (which is already bridged to channel B), but I'm running into some issues. I know the uuid's from both channel A and B, but the documentation I found on att_xfer only seems to indicate a way to do this from DMTF presses occurring on channel A. my idea was to use xml_rpc to execute a lua script which would take a uuid as an argv and bind to the session with freeswitch.session(uuid). I tried this, but the audio breaks up with the session that the lua script binded too. Does anyone have any recommendations on how I might accomplish an assisted transfer w/o DTMF presses and bind_meta_app knowing only a uuid? Thanks. --matt

Linking problems with mod_portaudio.so module
by Jason White 27 Jun '09

27 Jun '09

I've already discussed this with a few members of the community, but I would like to raise it with a wider FreeSWITCH audience. Since upgrading to libtool 2.2.6a (now the default in debian testing), I can't successfully link mod_portaudio.so. The system is Debian Testing, x86_64 architecture. ldd -d mod_portaudio.so returns the following (after listing the library dependencies): undefined symbol: snd_config (./mod_portaudio.so) snd_config is from the Alsa library, libasound. mod_portaudio.la shows a reference to /usr/lib/libasound.la, all of which looks correct. I have also examined the build logs, without finding the problem, as there are no errors reported during linking and I didn't find any linker invocations with library parameters apparently missing. The ldd -d output: undefined symbol: snd_config (./mod_portaudio.so) linux-vdso.so.1 => (0x00007fffd31ff000) libm.so.6 => /lib/libm.so.6 (0x00007f0ccacf7000) libfreeswitch.so.1 => /opt/freeswitch/lib/libfreeswitch.so.1 (0x00007f0c ca8c6000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007f0cca6aa000) libc.so.6 => /lib/libc.so.6 (0x00007f0cca357000) libncurses.so.5 => /lib/libncurses.so.5 (0x00007f0cca118000) libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007f0cc9e08000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007f0cc9bed000) libodbc.so.1 => /usr/lib/libodbc.so.1 (0x00007f0cc998d000) /lib64/ld-linux-x86-64.so.2 (0x00007f0ccb1d1000) libdl.so.2 => /lib/libdl.so.2 (0x00007f0cc9788000) libltdl.so.7 => /usr/lib/libltdl.so.7 (0x00007f0cc957f000) I spent several hours yesterday trying to debug this one. Any suggestions would be welcome. At this stage, I'm not sure whether it's a FreeSWITCH problem or a bug in libtool, or elsewhere.

Event socket chunks don't always end with 2 line breaks?
by Lon Baker 27 Jun '09

27 Jun '09

In the latest SVN this seem to be true for CHANNEL_HANGUP, which appends the following after the normal line breaks. "Disconnected, goodbye.\n See you at ClueCon! http://www.cluecon.com/" Perhaps it can be changed to conform the chunked data structure? variable_disconnect_message: Disconnected, goodbye. See you at ClueCon! http://www.cluecon.com Just a thought. Lon

Version 1.0.4 not working with custom channel variables?
by Adam Wilt 27 Jun '09

27 Jun '09

Hi, I recently tried upgrading FreeSWITCH from 1.0.2 to 1.0.4pre8 on my server, but the application I wrote uses custom channel variables which I create using "setVariable" in Python. In version 1.0.2, I am able to retrieve that variable within the event xml (it prepends the variable name with variable_). But in version 1.0.4pre8, these variables are missing from the xml events. Could this be a bug? Thanks!

Bug reports
by Brian West 27 Jun '09

27 Jun '09

FreeSWITCHers, We have written an extensive guide on posting bugs to jira. Over the past few weeks everyone has been a little lax in posting the correct info the first time. The questions we ask are NOT optional to fill out.. You must fill out every question on the list and "doesn't apply" or "n/a" are not acceptable answers. So help us help you fix your issues that you report. Remember provide all the details even if you think its not relevant to the issue at hand because even the smallest detail can help me reproduce your issue or result in me pulling my hair out and going crazy. :P http://wiki.freeswitch.org/wiki/Reporting_Bugs Also I would like to solicit volunteers to help manage, track and collect info for any Jira's please contact me... I have asked a few times but very few expressed interest in helping. Brian West brian(a)freeswitch.org -- Meet us at ClueCon! http://www.cluecon.com
