ESL command completion
by Josh Rivers 26 Nov '09

26 Nov '09

Is there a way of determining if a call-command sent to a session via ESL has completed? Is there a return event which is always fired? Is there a identifier I can use to verify that the return event matches my command? Thanks, Josh

Handling the 302 Moved Temporarily response from JavaScript
by John Platts 26 Nov '09

26 Nov '09

I have considered writing JavaScript code to bridge two calls together. However, I would like to perform custom handling of the 302 Moved Temporarily response. How do I handle the 302 Moved Temporarily response if I use JavaScript? _________________________________________________________________ Bing brings you maps, menus, and reviews organized in one place. http://www.bing.com/search?q=restaurants&form=MFESRP&publ=WLHMTAG&crea=TEXT…

Grandstream gateways
by Samuel Mukoti 25 Nov '09

25 Nov '09

Hi all, I'm wanting to try out a my first large scale setup at the office, 200 extensions and 24 POTS incoming, also a T1 line once the telco guys are ready. I wanted assistance with choosing the most appropriate hardware. We already have about 150 analogue phones, and I was wondering what's best? A couple of grandstream FXS GXW4024? Also for my POTS lines, gxw4108 FXO gateway or is it better to buy a sangoma or digium card? The best voice quality is paramount. Lastly for T1 what cards are recommeded, I was also proposing to use a Dell T116 Quad core intel i7 8G DRAM, would that perform? Or do I need hardware transcoding?

Patch: VMD Configurable MIN_TIME
by Andrew Fritz 25 Nov '09

25 Nov '09

I've created a patch to override the value of MIN_TIME in the vmd modules using a channel variable. In this way, it can be configured on a call by call basis. The channel variable is name "vmd_min_time". I didn't add the other detection parameters, but doing so would be straight forward. So, in our app, we can catch T-Mobile and the other problematic cell carriers beeps. I did this because in our app, we would rather have false positives than miss the start of recording on a voice mail system. This way, anyone using the VMD module can configure the vmd module to be as touchy or hard to trigger as they would like. I not sure how to implement it (at least in the vmd module code), but a way to make mod_vmd more robust to false positives, especially with short beeps would be to have it look for short silence immediately proceeding and/or following the beep. I've noticed that it tends to trigger on noise if there is tone in the noise, if for example I extend a syllable in a word or I have music on in the background. However on a voice mail system there will likely be a short near silence before the tone and an indefinite silence after it. In fact, background noise should be non-existent, except for line noise which should be Gaussian and not look like a structured tone. Looking for a beep + near silence after it for some period should eliminate many false positive where tones are embedded in other sounds (e.g. music or someone holding a vowel for longer than normal).

Hello all, is there a way how to enable very short recordings (1-3 seconds) in FreeSWITCH other than editing source code and recompiling? Thanks for your time! Best regards, kokoska.rokoska

How to find whether the destination extension supports encryption
by Yehavi Bourvine 25 Nov '09

25 Nov '09

Hello, We have a mix of phones that support RTP encryption and those that do not. I have to support both types in the meanwhile, and would like to have encryption enabled on the relevant leg, even if the other leg does not support it (why? one of our ATAs either must have it unencrypted or have it encrypted, but cannot have both). How do I find whether the *destination* supports encryption? I do not want to manage an additional table in the database... Thanks! __Yehavi:

mod_conference kick to abort invitations
by Jan Thiemo Fricke 25 Nov '09

25 Nov '09

Hi members, I'm controlling freeswitch with the conference module via xmlrpc. Is it desired that the kick command can only kick users that are connected to the conference? Is there no chance abort an invitation? The kick command has no effect until the person I invited with the dial command is connected. Thanks in advance! Jan

modify SDP for 200 OK
by Juan Backson 25 Nov '09

25 Nov '09

Hi, If I am using proxy_media=true, bypass_media=false, is there anyway of modifying o= and c= so that it won't show the IP of the far-end B leg? I am using fs as b2b2a and I want to hide the far-end ip as much as possible. I got to hide the IP for invite by modifying the sdp within C code, but I don't know how to do that for 200 OK. Any idea? Thanks, jb
