Re: [Freeswitch-dev] About module "Mod_pandsp", send the fax by email
by sparklezou 19 Dec '12

19 Dec '12

Hi All, I would like to implement the following feature on fax module "Mod_pandsp". Fax-to-Eaml, this feature should be simular to "Voicemail-to-Email". 1. hardware fax detection, then invoke "Mod_pandsp" at FreeSwitch side. Then send the received fax to the individual email. The email info should be set in the user account. 2.software fax detection, detected by "spandsp_start_fax_detect". But it should "answer" the call firstly. 3. The caller part side wait for a fax tone manually, then start to transfer the fax. Answer the call as common. Then press "*" or "#" to send fax tone to receive fax by email. Email-to-Fax 1. send the document which should be faxed as attachment. and in the email title, it's the destination number. 2. Freeswitch will check the mailbox timely. send the fax. Then reply one email, success or NOT. Thanks! 2012-12-18 sparklezou 发件人：sparklezou 发送时间：2012-11-27 07:52 主题：Re: Re: [Freeswitch-dev] About module "Mod_pandsp" 收件人："freeswitch-dev"<freeswitch-dev(a)lists.freeswitch.org> 抄送： Hi All, Correct! I hope the emaill function for voice-message and fax file coulde be combind. Both "Mod_spandsp" and "Mod_voicemail" could get the usre email configuration from the user profile. such as the current "vm-enabled", "vm-mailto", "vm-mailfrom" parameters in voice-message. It will be much easy to implement fax2email function. And much more coupling. Most of the email fuctions should be the same for both modules. Thanks! 2012-11-27 sparklezou 发件人：Abaci 发送时间：2012-11-27 02:57 主题：Re: [Freeswitch-dev] About module "Mod_pandsp" 收件人："freeswitch-dev"<freeswitch-dev(a)lists.freeswitch.org> 抄送： I think what he's looking for is automatic fax to email like Voicemail to email is handled. this is not something FreeSWITCH has, not sure if it's because of related patents or something else.

I means, set all of the related parameters in the user configure file. such as "vm-enabled", "vm-mailto", "vm-mailfrom", and so on. Also the mail sender configuration, such as SMTP. Something seemd the same, send "voice message" via eamil. Send "fax file" via email.

A bug in dealing with buggy DTMF handling?
by Örn Arnarson 18 Dec '12

18 Dec '12

Hello, I'm dealing with an end device whose designers don't seem to grasp the concept of negotiation. The device in question "supports" inband DTMF as well as RFC2833. However, once you set it to either, it will blindly use it, regardless of the support of the other end. I have a scenario now where I set dtmf_type=none, and export dtmf_type=none in the dialplan for certain calls, and this works beautifully for devices that actually listen and don't transmit RFC2833 when it's not an option in the SDP. However, when the device sends RFC2833 in spite of it not being supported as per the SDP, FreeSwitch will send the DTMF to the b-leg as SIP-INFO, despite dtmf_type having been set to none. If I export dtmf_type=rfc2833, it will correctly use RFC2833 for the b-leg. If I do not export it at all it will also use RFC2833. Most likely, it's not intended for FS to use SIP-INFO when explicitly told to use inband, even though the device on the A-leg is buggy. Any thoughts on the matter? Is this a conscious choice? I'm running FS stable, version 1.2.3. Regards, Örn

FreeSWITCH Weekly News and Notes
by Michael Collins 17 Dec '12

17 Dec '12

A happy and cold (in the northern hemisphere) Monday to you all! I'd like to start this week's news and notes by alerting everyone to the fact that there's been a significant addition to the functionality of the XML dialplan. If you've been around FreeSWITCH for any length of time you've probably read the words, "Nested conditions not allowed!" in yours or someone else's FreeSWITCH logs. As of last Friday<http://fisheye.freeswitch.org/changelog/freeswitch.git?cs=9b7b46dbca9c4c458…>that has changed! In response to Jira FS-4935 <http://jira.freeswitch.org/browse/FS-4935> Anthony has added provisional support for nested <condition> tags inside the dialplan. (Thanks to IRC user vipkilla for adding this to the wiki<http://wiki.freeswitch.org/wiki/Dialplan_XML#Nested_Conditions>already.) As you may know we are working the second edition of the FreeSWITCH "bridge" book<https://www.packtpub.com/freeswitch-1-0-6-build-robust-high-performance-tel…>. I will be updating chapters 5 and 8 to reflect this new change. It seems appropriate that with this new feature we should talk about it on this week's conference call<http://wiki.freeswitch.org/wiki/FS_weekly_2012_12_19>. Ken Rice and I will work up some simple examples of how to use the nested conditions and how they relate to the existing XML dialplan controls such as the break attribute and the regex tag. If you have a dialplan example that works well with nested conditions please email Ken and me off list. One last reminder for our Windows users: Dave Kompel shared with us some useful information <http://wiki.freeswitch.org/wiki/FS_weekly_2012_12_12> for gathering debug data when FreeSWITCH crashes under Windows. Our other main Windows guru, Jeff Lenk, was also on the call and gave some helpful input. If you are running under Windows you now have more tools at your disposal with which to analyze crash data and open Jira tickets. Have a great week and we'll talk to you on Wednesday. -- Michael S Collins ClueCon Team http://www.cluecon.com 877-7-4ACLUE

app that sends and receives faxes
by hagai sela 17 Dec '12

17 Dec '12

Hi, I want to write a small C# app that sends and receives faxes over SIP/RTP/T.38 and I thought about using FreeSwitch. I tried to look for examples on this and couldn't find any. Can anyone post such an example? Thanks.

Best way to test DID is hitting Freeswitch
by Everyday User 17 Dec '12

17 Dec '12

I have thousands of DID's and wondering what is the best method to run tests to see if these numbers are hitting our Freeswitch server. We have problems with our carrier assigning our numbers to other companies and need to preemptively know if the number is not pointing to us anymore before our clients find out. Currently, I run a command to originate a call for each DID which updates a database entry to see if that number went through are server. I am looking for a more efficient way to test all these numbers. Thanks. - Jim

Stereo support?
by Xijing Dai 14 Dec '12

14 Dec '12

hey guys, Have anyone try to implement stereo support in freeswitch to streaming the music? I tried, but only 1 channel is hardcoded inside freeswitch code everywhere, i can't make it work properly, just wonder if any1 tried before? Can we share some experiences? What I tried: File IO needs to support 2 channels shout module needs to support 2 channels L16 needs to support 2 channels it should auto convert between 1 channel codec and 2 channel codec for encoding/decoding. The problems I had are: * some random RTP sending error. (using PCMA codec, before encode, i did convert audio from stereo into mono). * music voice becomes noise. ( I tried to use MPG123_FORCE_STEREO to convert 1 channel music to 2 channel music). Cheers Xijing

How to find out what changed in a release
by Craig Ayliffe 11 Dec '12

11 Dec '12

Hi, I am looking at the ChangeLog in the tarball for the latest release 1.2.5.3, and it doesn't have an entry. Plus I also noticed the last two entries (1.2.5.2 and 1.2.5.1) in the ChangeLog also just say 'Maintenance release/bug fixes'. So how would I find out what has changed, i.e. which bugs have been fixed in each release? Regards, -- Craig

10 Dec '12

Greetings! We are glad to report that the FreeSWITCH team has tagged version 1.2.5.3. You can download the tarball here<http://files.freeswitch.org/freeswitch-1.2.5.3.tar.bz2>. Anyone using 1.2.5.x should update as soon as possible. We appreciate all those who have helped us with testing and tracking down some sneaky and pernicious little bugs. On last week's conference call<http://wiki.freeswitch.org/wiki/FS_weekly_2012_12_05>we spent some time talking about the XML parser and some of its pre-processor directives. We discussed specifically how you can use the "exec" command to execute a shell script in the middle of XML processing. We also discussed a few tricks on how to look at the source code when you need to learn about some FreeSWITCH functionality that otherwise is not documented. This week's conference call<http://wiki.freeswitch.org/wiki/FS_weekly_2012_12_12>subject is still pending, so stay tuned! One other item I'd like to mention is that we've had several reports of FreeSWITCH success stories. We will be providing more information about those in upcoming stories on our Web site. We've got people using FreeSWITCH in various situations as well as software developers who've added support for FreeSWITCH to their offerings. The FreeSWITCH ecosystem continues to grow and flourish! Thank you all for being a part of it. Take care and have a great week! -- Michael S Collins ClueCon Team http://www.cluecon.com 877-7-4ACLUE
