[Freeswitch-dev] FreeSWITCH on Windows crashing when doing deflect/REFER
by Peter Olsson 12 Oct '09

12 Oct '09

I have a problem with FreeSWITCH (r13175) when using REFER. If running inside Visual Studio, everytime (during the REFER) I get a "...has triggered a breakpoint". It's possible to click continue to go on, but eventually (another 2-3 calls) FreeSWITCH crasches completely. When running outside Visual Studio I get a crasch after maybe 10 calls. Another interesting scenario is when running outside the debugger and I enable siptracing it's much more stable - even though it crasches eventually - this is what makes me wonder about mutexes... I've tracked it down to calls to malloc() and calloc() which in 100% of the cases is in the top of the call stack. My thought is that it might be related to a mutex issue somewhere. Below I've copied the call stack from two times it's happened to me. These are the most common traces, but sometimes it's a malloc being called from the sqlite lib. But so far I always think it's been related to a malloc/calloc. These things have occured in a couple of other places as well, for instance when a SIP registration fails (registering to an external server) with error 404 I also get a breakpoint triggered, but I don't think that has caused any crasches yet. I've tried to debug this on my own, but so far I didn't find anything, so that's why I'm asking you guys :) I think I'm going to try the same on Linux as well, and see if it works differently there. If you need more info, please let me know, I'll try to help out as much as possible. I thought I'd post this here first, if you have any ideas. If not I'll file a Jira for the issue. ----- ntdll.dll!DbgBreakPoint() [Frames below may be incorrect and/or missing, no symbols loaded for ntdll.dll] ntdll.dll!RtlpNtMakeTemporaryKey() + 0x3eee bytes

[Freeswitch-dev] Scalabilty of Freeswitch
by Jerry Richards 02 Sep '09

02 Sep '09

Hello All, Does anyone know what the capacity of a stand-alone Freeswitch (assuming a top-of-the-line server), in terms of how many users? Also, when that number is exceeded, how can Freeswitch server be distributed to accommodate a larger installation? Best Regards, Jerry

[Freeswitch-dev] Fwd: FS + G729
by mauro＠nohad.com.br 31 Aug '09

31 Aug '09

Hi there Interesting point. We have licenses for 723 and 729 for asterisk, and we also need to use asterisk distribution to talk with our voice card for PSTN. We dont have the drives for this card developed for freeswitch yet. So, for us the freeswitch is a great solution, and were beginning to use it, but for now we also must use asterisk for some things that: or we dont know how to do yet, or we feel more comfortable with, or we have to. I think that this is a conservative and secure approach for us, since we just beginning to scratch freeswitch. We tried to do exactly what is described in the message (bottom) but we have no success. Like I said we use and must to use asterisk for now, and we already have the 729 and 723 licenses. I know that 729 (and 723?) license like asterisk is on the way, and also know that there is at least one vendor for 729 for freeswitch, but it will be great if someone could give us the direction to make a extension registered in freeswitch to talk with another thought asterisk to make the codec trans-coding in asterisk. I also support the idea to solve things like this in the freeswitch project (were not talking here about asterisk) but for now (for us) to make a good use of the 923459283752938 good things in freeswitch we must to use it together with asterisk. Any idea to this direction (transcoding thought asterisk) would be great appreciated.

[Freeswitch-dev] Question about mod_limit
by Anatoliy Kounitskiy 31 Aug '09

31 Aug '09

I have question about mod_limit: is there a reason to have difference between the api applications and the dialplan? I mean when you use db function from the cli you can use insert/select/delete but when you use it from the dialplan you can only use insert/delete. #define DB_USAGE "[insert|delete]/<realm>/<key>/<val>" #define DB_DESC "save data" SWITCH_STANDARD_APP(db_function) but in the SWITCH_STANDARD_API(db_api_function) i have three options insert,delete and select What i try to accomplish is to be able to insert values from the dialplan and after that to be able to use them ( to select and use the result) from another extension.

[Freeswitch-dev] Portaudio upgrade
by Tamas 29 Aug '09

29 Aug '09

Hello, I'm trying to upgrade the portaudio lib due to some issues with the sound card in my box (I've found issues on 2 different boxes). I'm trying to run FS on bleeding edge distro - as this is a desktop box requiring fancy things - Ubuntu Jaunty 9.04 x86_64/i386 I know that hot new ubuntu is not supported so I'm trying to work on by myself - and give back if I have anything reasonable :) As I saw on portaudio.com, there were some improvements with ALSA handling and it should handle newer cards better now (non-mmap patch): http://portaudio.com/trac/log/portaudio/trunk/src/hostapi/alsa/pa_linux_als… As I've seen, there is some fix for windows's wdmks stuff too. I'm not qualified to hack PA, but I can play with it a bit :) What I would need to know is, which version (and source - as there is a separate fork e.g. at audacity too) is the one the FS trunk is having and what fixes/changes had been applied to it before merge (if I have had the exact version of included PA, I could make a diff and see by myself). From FS svn log I can see what changes were since the version bump- From FS svn log I see, that at r8835 we had the last version bump: r8835 | anthm | 2008-06-25 00:15:50 +0200 (sze, 25 jún 2008) | 1 line merge in newer portaudio Are the changes in FS regarding PA sent to upstream? (I know, PA is used to be pretty non-responsive) Maybe it would be good to store the last PA version and source data in tree to be able to upgrade easier in the future. We are interested in improving the quality (mainly on windows) as we try to use this excellent stuff as a softphone base :) Regards, Tamas

Re: [Freeswitch-dev] [Freeswitch-users] how to avoid many "|" in bridge application?
by Carlos S. Antunes 25 Aug '09

25 Aug '09

Max, I would like to see something similar too. For example, it would be wonderful if one could specify multiple gateways to try like this or something similar: <action application="bridge">  <gateway order=1 data="sofia/gateway/gw-1/1$1"/> <gateway order=1 data="sofia/gateway/gw-2/1$1"/> <gateway order=2 data="sofia/gateway/gw-3/1$1">  </gateway> <gateway order=3 data="sofia/gateway/gw-4/1$1"/> </action> One would be able to avoid the "[]" and "{}" hacks and combine sequential and simultaneous trying of gateways. What do the developers think of this?

Hello Freeswitch Developers, I work for an linux solution provider in spain and have lot's of experience in developing for opensource software (freeradius) and adminstration. We have quite a few clients with asterisk solutions and some pretty cool projects in our queue but we have expierenced a lot of problems with asterisk. After reading the freeswitch introduction from Anthony Minessale i at once felt at home with freeswitch as the project seems to be what I wanted from asterisk. As i am a very deep debian enthusiast I want to bring the debian package into debian itself, which means bringing it policy compliant. Which as one of the more problematic moves means: changing all directorys to be debian compliant. i really would love to do this officially as the debian maintainer for the freeswitch project, i already sent the current packet builder an email but I did not receive an answer until know. I hope we can work together and that i will be accepted into this project which has in my oppinion a very bright future in the telecomm business! all the best, -- Raimund Sacherer - RunSolutions Open Source It Consulting - Parc Bit - Centro Empresarial Son Espanyol Edificio Estel - Local 3D 07121 - Palma de Mallorca Baleares
