Some things like Mute and Deaf are dynamic and I want to control them with application code (JavaScript in this case). In regards to using multiple profiles & conference controls for any one conference. The mod_conference Wiki says it is not possible/practical. What would happen if the same conference name was used with two separate profiles? Does it use the profile to set up the member or does it use the profile to affect the entire conference? The comments by Bret McDanel would seem to indicate that the later effect occurs, when a profile is specified for a conference, it affects the entire conference. Sometimes you have to go by the axiom "The devil is in the details." I have not looked at mod_conference.c. In this case, I would like to check to see what the code is doing. And: Yes, I could use the more multiple profile/control capability. But I still would like the capability I have proposed which would have the mod_conference code do the loop over the members to do mute and unmute when I want to mute/unmute a class.

static libfreeswitch.a OSX
by Paulo Vicentini 10 Jun '10

Hi, I am trying to link my application against libfreeswitch.a (statically) on mac os x but I am getting undefined symbols (it happens even with freeswitch ). If I use libfreeswitch as a shared lib..it does work. Have you faced such issue on Mac? Is -static linking with libfreeswitch.a a problem? Thanks

mod_conference - User Classes
by David Swardstrom 09 Jun '10

Video is a separate topic. Would like to get into it someday. I refer you to the following example of a conference. This is the type of conference capability I am replicating to FreeSwitch. http://www.conferencecall1.com This type of conference requires an IVR front end to determine the room number and Host identifier. It also requires additional IVR capability to handle the menu enabled by a menu key. One of the features of this conference type is the ability to mute everyone who did not login as a host. I have used several different conference systems and have been working with the RemoteLink conference capabilities for over a year. Recently I spent some time looking at a outside "free" conferencing capability. I really have several primary goals: * Simple conferencing, * Replicate RemoteLink conferencing, * Provide a configurable system that can do even more sophisticated things. In conference types, there could be the capability of having more than two classes of Conferees. I have come up with 5 that seem to fit the range of capabilities desired. * Classes whose members are always allowed to speak. Host/Moderator - Owner of the conference. Assistant - Someone one who can control the conference (not owner). Speaker - Think of this as a panel or a series of speakers. * Class of conferees that can be muted or unmuted by host/assistant control. Guest * Class of conferees that are never allowed to speak Participant I spent some more time looking over the mod_conference code and think that I would like to add two flags: * guest * listener At this time I do not see the need to have mod_conference track the difference between the 3 classes of speakers. Any API that uses “CONF_API_SUB_MEMBER_TARGET” is a potential user of these flags. For example. > To allow the capability to mute/unmute all guests. * mute <confname> mute <[member_id|all|last|guest]> * unmute <confname> mute <[member_id|all|last|guest]> > To allow the capability to deaf/undef all guests and listeners. * deaf <confname> mute <[member_id|all|last|guest|listener]> * undeaf <confname> mute <[member_id|all|last|guest|listener]> > To kick off guests or listeners only leaving the speakers: * kick <confname> mute <[member_id|all|last|guest|listener]> Note: I have found some other surprises in the code that I will address some other time.

FXS bridged on FXO ports and DTMF
by devel＠thom.fr.eu.org 08 Jun '10

08 Jun '10

I come back on this topic as I did not find a clean/good solution to this problem. As reminder, the problem occurs when an FXS channel is bridged on an FXO channel (seen with sangoma A400 hardware with HW DTMF detection). The problem is that each leg of the bridge is detecting the inband DTMF, and so freeswitch sends each detected DTMF from one leg to the other, and so on and so forth (as each leg detects the DTMF again and again). I guess what would be needed for these cases is some application that would prevent detected DTMF to be sent to the other leg. Can anybody give me a hint on whether or not such application exists, and if not, a starting point to try to create one. Thanks François

Hi, I find a way to send ssml directly to the tts, but I can't see a similar function for sending srgs to asr? Does this exist or will I need to add it? Jan

mod_conference - User Classes
by David Swardstrom 07 Jun '10

07 Jun '10

One feature that many conferences have is classes of users. There is the Host/Moderator, speakers, and Guests/participants. In such conferences, the Host may have the ability to Mute all non-speaking Conferees. Currently this requires a separate flag for each user indicating the user class. To toggle conference level mute, the application will need to get a conference list and run through it. For each conferee in the list, the current mute status and user class must be determined. I would like to propose introducing a new member flag: speaker. This indicates that the member is a speaker and should not be automatically muted. This would be provided as a “speaker” flag as part of the status on a list. A new set of Conference APIs would be also be provided: mute & unmute at the conference level. When issued, any member that does not have a moderator or speaker flag set would be muted or unmuted. If the conference is “guest muted”, the first line of the list API response would indicate this a “muted” similar to the locked indicator currently provided. If this seems like a reasonable proposal, I would take a stab at modifying mod_conference and testing it and then submit it via a Jira request. Regards, Paul David Swardstrom

Core dump after 'Auto Changing port'

I am calling into freeswith which is on a public ip from a soft phone behind a NAT'ed ip. The call connects and I can hear the playback of the configured audio file but only for a second before a core dump with the message below. 2010-06-05 23:33:59.228651 [INFO] switch_rtp.c:2049 Auto Changing port from 192.168.1.24:8000 to xxx.xxx.xxx.xxx:8000 Segmentation fault (core dumped) Any ideas on what this could be?

JavaScript - how bad is it?
by Jan Berger 05 Jun '10

05 Jun '10

Hi, I know from a previous postings/discussions that the Javascript we use is considered to be bad - performance and memory wise. Can someone explain a little - who did the Javascript integration? The reason I ask is because I am working on ccxml and vxml - and I need to add ECMAScript due to compatibility with external tools/libraries . The impression I get from wiki is that Lua perform 2 x the speed of JavaScript - does anyone know exactly why? Jan

What is the current shape of T38 support in mod_fax in the trunk? Is it ready for prime time (real world use) or is it still in development? Peter
