halp! newb question on setting up providers..
by Bret-lists Watson 30 Jun '11

30 Jun '11

Hi All, getting freeswitch up and running - heaps easier than asterisk.... but.. I can't seem to work out what and where to put things for configuring my provider.. there seems to be a number of ways to do it.. currently I have it set in my vars.xml under default_provider.. <X-PRE-PROCESS cmd="set" data="default_provider=sip.pennytel.com"/> <X-PRE-PROCESS cmd="set" data="default_provider_username=6189xxxxxx"/> <X-PRE-PROCESS cmd="set" data="default_provider_password=xxxxxx"/> <X-PRE-PROCESS cmd="set" data="default_provider_from_domain= sip.pennytel.com"/>  <X-PRE-PROCESS cmd="set" data="default_provider_register=true"/> <X-PRE-PROCESS cmd="set" data="default_provider_contact=sofia/internal/ sip:102@192.168.1.22:5060"/> when I try and ring my mobile I get.. 2011-06-29 17:39:42.269994 [WARNING] sofia_reg.c:1329 SIP auth challenge (INVITE) on sofia profile 'internal' for [041xxxxxxx(a)192.168.1.76] from ip 192.168.1.22 2011-06-29 17:39:42.610032 [NOTICE] switch_channel.c:890 New Channel sofia/internal/102(a)192.168.1.76 [cda831fb-e8f5-4c64-936a-1562691f15cf] 2011-06-29 17:39:42.657134 [INFO] mod_dialplan_xml.c:336 Processing Kitchen <102>->041xxxxxxx in context default 2011-06-29 17:39:42.745992 [ERR] mod_sofia.c:4141 Invalid Gateway 2011-06-29 17:39:42.745992 [NOTICE] mod_sofia.c:4508 Close Channel N/A [CS_NEW] 2011-06-29 17:39:42.745992 [NOTICE] switch_ivr_originate.c:2443 Cannot create outgoing channel of type [sofia] cause: [INVALID_NUMBER_FORMAT] 2011-06-29 17:39:42.745992 [INFO] mod_dptools.c:2680 Originate Failed.

FreeSWITCH Cookbook - New recipes needed
by Michael Collins 29 Jun '11

29 Jun '11

Hello all! I've replaced the old recipe list with a new one. The link is still here on the wiki along with other information for prospective authors: http://wiki.freeswitch.org/wiki/Cookbook#Information_for_prospective_authors We've made a few changes to the content. Specifically, we've removed two chapters: "Call Center Services" and "Carrier Class Services". We do not feel that these can properly be done in "recipe" format. So instead we've take a few of the recipes from those chapters and put them into the "misc." section on the FSCB recipe list. We invite your input on what to replace them with. What do you think? What recipes would you like to see? Send use your ideas. Thanks, Michael

pause and restart while recording?
by Wes 29 Jun '11

29 Jun '11

I couldn't find much on this: Is it possible in lua script to let the user press a key to pause recording, and press a key again to continue the recording, just like a traditional recorder? Thanks!

SRTP problem with leg B inbound to FreeSwitch
by Jim Miller 29 Jun '11

29 Jun '11

I've gotten as far as I can with this problem and could use some help. Here's the problem: - Two soft phones can dial each other (ext 1001 and 1002) and voice works in both directions - Wireshark shows Leg A in/out from phone 1 (10.1.10.5) is SRTP and Leg B out from freeswitch (10.1.10.2) is SRTP. However Inbound from phone 2 (10.1.10.4) to the switch is just RTP. Any ideas? I've read what I could find on the freeswitch wiki and made the obvious changes to the dialplan  <action application="export" data="sip_secure_media=true"/> and then did this to the internal.xml sofia config  <param name="inbound-late-negotiation" value="true"/> Using Freeswitch version 1.0.head (git-2486306 2011-06-23 11-57-38 -0500) Blink is being used as the soft phone v0.24.1 released in May 2011. Linux and Mac versions. I've also tried sflphone for a linux host with no change in the behavior. If I bypass the media stream and send the SRTP between the soft clients directly all works fine. I've attached various stripped down dialplans, sip configs, and a wireshark packet dump. Thank you -Jim

Proper prompt gain/level
by Bryan Smart 29 Jun '11

29 Jun '11

As part of creating prompts for my IVRs, I've tried to match the audio gain of my prompts with the gain of the stock English prompts. During this process, I noticed that the English Callie prompts are recorded extremely low (max gain around -16DB). I have the Cepstral Callie voice, and I must set the Cepstral volume to about 50% in order to match the gain of the English prompts. In conferences and other situations where prompts are played over conversations, the level of the prompts are obviously low. I can, of course, renormalize the gain of the prompts up to -10DB or more with a sound editor. However, I wonder if there is a better way to change the level of the prompts, or if there is a good reason for the prompts to be encoded at such a low level. I haven't considered all of the implications yet, but I'm fairly sure that encoding the prompts this quietly is not the best approach, even if it is desirable for the prompts to play quietly on a call. For each 6DB reduction in gain, there is a 50% reduction in perceived volume, and one less significant bit is used for storing the audio. In a 16-bit file, a maximum gain of -16 means that only the 14 least significant bits are actually used for encoding the audio. This results in a reduction in dynamic range, but the difference isn't really noticeable as long as the data remains 16-bit. The problem comes when the audio is converted to a different bit depth. For example, most quickie routines for converting 16-bit audio to 8-bit audio will simply chop off the 8 least significant bits. Therefore, when the prompts are converted to 8-bit audio for use by most of the narrow band codecs, the prompts are only using 6 bits of audio. If the volume of the channel is increased, then the 6 bits are promoted, and the dithering errors at the bottom become louder. In the worst case, since these prompts are only encoded with 14 bits of actual data, and converting to an 8-bit channel will only leave 6 bits of actual data, boosting the gain of the prompts on an 8-bit channel to full loudness would result in the noise floor (the level of the dithering crackle) being about -18DB. That's almost as loud as the prompts themselves sound at the moment. Anyway, regardless of observations, is there a reason why the prompts must be recorded so quietly? If I'd like them louder (without increasing the gain of the entire channel), is there a way other than running them through a tool to renormalize their max levels? Bryan

FreeSWITCH Conf Call Today: Plivo, an OSS Twilio Alternative
by Michael Collins 29 Jun '11

29 Jun '11

Hello all! Today's conference call is busy! We have Venky from the Plivo project discussing the new software. We also have quite a few new FS items that have been added in the last month so we need to get some documentation done. :) Here's the agenda: http://wiki.freeswitch.org/wiki/FS_weekly_2011_06_29 There is a link in there to a PPT for us to look at during Venky's presentation. Talk to you soon! -Michael

Copy custom SIP headers - {sip_copy_custom_headers=true} doesn't seem to be working
by Jonas Borjesson 29 Jun '11

29 Jun '11

Hi all, As many others, I need to copy customer X-headers from leg B back over to leg A and have found a few threads talking about using the sip_copy_custom_headers=true with the dial string but this does not seem to be working. I am doing exactly what is described in the thread below but like that guy, it does not work for me either and that thread never came to any conclusion. Does anyone know the status of this feature or what I may be doing wrong? Any help is greatly appreciated! Of course, I tried on the latest and greatest FS - 1.0.head-git-4962542 2011-06-27 10-15-03 -0500 The tread talking about this very feature: http://comments.gmane.org/gmane.comp.telephony.freeswitch.user/36287 And documentation: http://wiki.freeswitch.org/wiki/Variable_sip_copy_custom_headers Thanks, /Jonas

While executing a lua script, I got this error.
