Multiple ring with mod_fifo
by Eduardo Nunes Pereira 15 Jun '12

15 Jun '12

Hi, folks I have two members in my fifo, and i want to ring the two members when a call comes into fifo, so i had tried many ways to accomplish, but no success, my fifo file conf is: <configuration name="fifo.conf" description="FIFO Configuration"> <settings>  </settings> <fifos> <fifo name="cool_fifo@$${domain}" importance="0"> <member timeout="60" simo="1" lag="20">{call_timeout=30,fifo_member_wait=wait}user/2001@$${domain}</member> <member timeout="60" simo="1" lag="20">{call_timeout=30,fifo_member_wait=wait}user/1000@$${domain}</member> </fifo> </fifos> </configuration> I have tried put simo="2", but nothing, sorry my limited idea of fifo, is possible to ring multiple phones registered in the fifo ? -- Eduardo Nunes Pereira skype: eduardonunesp msn: eduardonunesp http://about.me/eduardonunesp

Developers' Salon, sched_broadcast from FreeSWITCH-CN
by Seven Du 15 Jun '12

15 Jun '12

All, Sorry I didn't promote as it's mainly targeted to the Chinese Community and it's the first Salon in China and we want to keep a low profile. I'm the creator and maintainer of FreeSWITCH-CN(http://www.freeswitch.org.cn ). We'll have a Salon at this Sunday (June 17th, UTC+8) afternoon in Beijing, China. http://www.freeswitch.org.cn/blog/past/2012/4/16/freeswitchcnzhong-wen-she-… According to http://freeswitch-cn.eventbrite.com/ , we have 56 registers till now and we do accept blind reg. It will be in a coffee bar and if anyone happens to drop by is welcome to have a cup of coffee. The Chinese Community is growing and I will can have more news to ClueCon. And I have one news now. I personally received the first donation a few days ago for the in-writing book: FreeSWITCH in Action (You won't use this name in the second edition of FS book, right? Michael :) ) , it's published on site using CC-BY-NC-ND. http://www.freeswitch.org.cn/document My aim of running the FreeSWITCH-CN community was to help Chinese speakers to learn FreeSWITCH. And I had put a Paypal donation button on and planed to donate back a percentage to the core developers but get nothing till now. I just figured out that there's basically no way for us legally collecting money in my country publicly. So I replaced the paypal donation to a guide link directly to freeswitch.org and if anyone donate with a remark of FreeSWITCH-CN it's probably from our community, or probably never. Anyway, I will use the first being-donated-money to buy a few things and will give out at the Salon, it's not that much, but it's something. And if there's future donations happens privately to me I will definitely happy to donate back to upstream. Ok, back to the Salon. I will report more here after the Salon and probably we could run a tiny ClueCon in China next year?

Brute-force attack
by ocset 14 Jun '12

14 Jun '12

Hi I have deployed Freeswiitch on windows 7 and since there is no fail2ban on windows, I was wondering what the real risk is with opening it up to the internet. If I was to ensure that all users and passwords were extremely difficult to guess (passwords like "2$53E_d7?^2!3s$"), what are the risks that I am exposing myself to? Is there a type of DoS for voip where hackers can just flood my system with requests simply to be malicious? There are VB windows scripts available that emulate what fail2ban does on Linux but I was just wondering whether I really need to implement this level of security if I can control the password complexity in Freeswitch. Thanks O

Re: [Freeswitch-users] Collect DTMF via mod_event_socket
by Peter Olsson 14 Jun '12

Or just listen for DTMF events, and act on those. I personally find that's the easiest approach. /Peter Från: freeswitch-users-bounces(a)lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] För Bob Coleman Skickat: den 14 juni 2012 10:18 Till: freeswitch-users(a)lists.freeswitch.org Ämne: Re: [Freeswitch-users] Collect DTMF via mod_event_socket Hi Venkatesh, You could use this: http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_play_and_get_digits or this: http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_read On the main page you go to the docs link at the top, then everything is linked off the left hand side Bob ________________________________ Date: Thu, 14 Jun 2012 01:07:13 -0700 From: vvenkatar(a)gmail.com<mailto:vvenkatar@gmail.com> To: freeswitch-users(a)lists.freeswitch.org<mailto:freeswitch-users@lists.freeswitch.org> Subject: [Freeswitch-users] Collect DTMF via mod_event_socket Hello !

SCCP Question
by Ron McCarthy 14 Jun '12

14 Jun '12

Hi List, Has anyone been running SCCP with a larger number of phones? Im looking to deploy like 75+ phones and I want to keep SCCP so I don't have to upgrade them and for the SLA, some phones also have no SIP software for them so im forced to keep SCCP. Does anyone have any experience with this? From what ive read the SCCP support works and works well, im just worried about trying to run this many phones and if im missing any sort of issues that could come up. I would like to use FreeSwitch instead of Asterisk for this, just worried about functionality and the stability of it. Thanks!

Is SCA bridgeing Multithreaded?

14 Jun '12

I see I can use Enterprise Originate :_: to connect calls to multiple phones in threads to speed things up. Does Shared Call Appearance connect in threads or sequentially? Thanks, Sean

Re: [Freeswitch-users] How to configure ring back for calls through freetdm?
by Peter Olsson 14 Jun '12

14 Jun '12

Try to set the channel variable "ringback" to the tone you want to play. /Peter -----Ursprungligt meddelande----- Från: freeswitch-users-bounces(a)lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] För Antonio Modesto Skickat: den 14 juni 2012 16:41 Till: Freeswitch Users Ämne: [Freeswitch-users] How to configure ring back for calls through freetdm? Hi, I've written a lua script to make calls using freetdm channels, the problem is that there is not a ringback tone to the calling party, so it's not possible to know what is going on until the caller party answers the call. What do I have to do to enable this?

Re: [Freeswitch-users] ESL originate - call events are sent too fast
by Peter Olsson 14 Jun '12

14 Jun '12

You will have to generate your own channel uuid and then set origination_uuid when you do the originate call in FS. Also, you will need to subscribe to this uuid before trying to originate the actual call. /Peter Från: freeswitch-users-bounces(a)lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] För Adam Raszynski Skickat: den 14 juni 2012 15:43 Till: FreeSWITCH Users Help Ämne: [Freeswitch-users] ESL originate - call events are sent too fast Hi all I have some little problem with events generated by ESL originated calls. Maybe someone had similar problem and could post how to solve it. I would like to originate call and receive events related only to that call. At the same time my originate script is executed multiple times i.e. 100 times. Current version of my script works like this: - send api originate [params]target via ESL - wait for originate response to get uuid - add filter: filter Unique-ID <uuid of my call> - subscribe for events: event plain CHANNEL_ANSWER CHANNEL_HANGUP CUSTOM spandsp::txfaxresult Unfortunately execution of all above statements sometimes take a while and in meanwhile FreeSWITCH generates event and send it back to my script BEFORE it has subscribed to receive events. It happens for example for very fast call answer or hangup. In that case I lost important answer or hangup event and all processing logic is broken. I've tried to change sequence of commands, but when I put event subscription before adding filter then I get events from other channels. I also can't add filter earlier because need to wait for originate response. Any hints on this? !DSPAM:4fd9f54532761072142040!
