Problems passing arguments to lua
by Nik Middleton 09 Feb '09

09 Feb '09

Hi Guys, I'm having some issues passing an argument to an lua script. Basically in an originate command I pass the name of a .wav file If I hard code the file session:streamFile("myfile.wav"]); It works, However, using this: session:streamFile(argv[1]); causes this error 2009-02-08 22:09:07 [ERR] mod_lua.cpp:176 lua_parse_and_execute() cannot open /usr/local/freeswitch/scripts/helloworld.lua,myfile.wav: No such file or directory Any Ideas? Regards

Mod_native_file FreeSWITCH files (and script) available
by Kristian Kielhofner 09 Feb '09

09 Feb '09

Hello everyone, Now that I've got FreeSWITCH compiling under AstLinux I'm starting to look at ways to optimize FreeSWITCH. First things first: minimize transcoding. I hate transcoding. I modified a concept I came up with back in the day for Asterisk. I've created a script to convert WAV files to FreeSWITCH mod_native_file formats for various codecs. Of course I also updated the wiki: http://wiki.freeswitch.org/wiki/Mod_native_file#Script_to_convert_a_sound_f… As you can see I've also converted the current FreeSWITCH prompts and MOH into various file formats (including G.729 and G.723). These files have undergone very little testing (basically none) so I would appreciate some feedback on them. I'm also working on G.729, iLBC, speex (VBR?!?), and G.722. What about Siren, CELT, and some of the others? I don't have much experience with these and I could certainly use some help. P.S. - I'm currently using sox and Asterisk res_convert to do the conversion. I don't know how else to legitimately (and consistently) convert to these various formats. Without bringing up the usual G.729/G.723 discussions, I'm in the US and this is how I could legally do all of these conversions. -- Kristian Kielhofner http://blog.krisk.org http://www.submityoursip.com http://www.astlinux.org http://www.star2star.com

Struggling with Originate
by Nik Middleton 09 Feb '09

09 Feb '09

Hi Guys, I'm placing calls ok by using the event socket. However, I need to modify the To: Sip header prior to the call going out for routing purposes. Is it possible to do this in the Originate action? If not, can someone explain if it's possible to trigger part of the dial plan externally? I can then modify the headers and then place the call/ Regards,

Transcoding G723
by Ali Al-Rubaie 08 Feb '09

Hi, I need FreeSWITCH to transcode from G711 to G723 but I couldn't do so because it supports G723 only in passthru mode. So, what's the solution? Thanks,

Seeking opinion on shared disk space
by Woody Dickson 08 Feb '09

08 Feb '09

Hi, In my deployment scenario, I plan to have two redundant freeswitch servers running on two different boxes. Two key features I am leveraging on freeswitch are voicemail and call recording and playback., and as a result of that, a shared storage for playback of the recorded wav files is needed. When the user traffic is high, I am affraid that NFS or even GFS can't scale well. On the other hand, a real SAN hardware with optical-fabric is too expensive for us. We are therefore considering using iSCSI SAN to build a cheap SAN for that purpose. Does anyone have experience setting up a shared storage between multiple freeswitch servers and can share some inputs with me? Thanks for all your help. Woody

Re: [Freeswitch-users] mod_shout delay in trunk
by freeswitch-users＠digitaldan.com 07 Feb '09

That worked great! I wanted to say just how awesome Freeswitch is, I have been doing voip related development with SIP since 2000 and this is by far the most well designed piece of voip software I have used or developed on. I currently have a homegrown sip server built on the NIST sip stack with Sun's JMF libraries for RTP processing. 95% of the code and complexity is handling the SIP and RTP sessions, the other 5% is the final application logic and what is most important to me . By letting freeswitch do whats its good at (call routing, sip and media handling) it allows me to focus on what I'm good at (what should we do with those streams, like record them). I have been bragging about this project to anybody who will listen!

Tell me if it helps you and i will consider making it configurable. On Fri, Feb 6, 2009 at 2:01 PM, < freeswitch-users(a)digitaldan.com > wrote: For me it is. For what I'm using it for I can tolerate around a second or two delay. I have the icecast server setup to only buffer 1K for their on-connect burst as well as my flash/flex player to only buffer 1k (yes I might as well not buffer at all, which I may end up doing). In 1.0.2 this worked very well. Is this buffer configurable? If not, where is it being set?

This is why you have this delay which is 100% normal.... is realtime a critical thing? It is shout cast so you know it doesn't have to be realtime.. in fact some clients will buffer a little bit anyway and add to it. /b On Feb 6, 2009, at 1:43 PM, freeswitch-users(a)digitaldan.com wrote: I have, do you know what would have changed between 1.0.2 and trunk that would cause the buffer to change? Also if its not in mod_shout.c (which I copied from 1.0.2 to trunk for testing with no luck), where else would fs be buffering? One thing I have noticed is that in 1.0.2 as soon as the dial plan hits my record statement I see mod_shout logging that it has connected to the icecast server, in trunk it takes about 5 seconds to see the same log mesage.

need suggestion on using mod_easyroute
by Juan Backson 07 Feb '09

07 Feb '09

Hi, I notice that there is a newly-developed mod_easyroute model available. Has anyone used it with large amount of routes ( ex > 1M ) on a high traffic scenario? For that kind of scenario, would it be better to consider using out-going event socket to serve that purpose? I would greatly appreciate any recommendation. Thanks, JB

Hi Guys I'm looking for some pointers on how to collect CDR's and store in mysql. Is there anything built in yet? I can rate the calls as a batch process, I simply need the call data. Regards

Outgoing registration expiry
by UV 07 Feb '09

07 Feb '09

I’m trying to set up a default provider via the example.com.xml using the variables set in vars.xml. The provider has a registration expiry of 120 seconds and I’m trying to set it up to register every 60 seconds but when I change the “expire-seconds” variable (in directory/default/example.com.xml), it doesn’t seem to have any effect. Actually, doesn’t matter how long I wait, it doesn’t seem to re-register at all… Any idea what I’m missing?
