Goal

Have max. 6 participants dial on to an asterisk pbx, make each of their voices individually available as a mono output. Each participant should hear the other participants plus an external input from the mixing desk (studio mics / music), but not hear themselves back.

Documentation should be provider for common platforms (linux, macosx, ms windows). Pick one voip client on each platform, and document every step from installation, configuration to connecting to the conference pbx and joining.

Todo

Needs a lot of testing in the field:

  • get a bunch of typical users to give up a few hours of their time, explain they will need to be patient and do exactly as we say
  • set up a conference bridge with different types of connections: pots, voip, skype to sip gateway
  • documentation
  • create sample set to guide users in joining the conf

Setup

  • ESI u46xl sound card (6 out, 4 in, sponsored by Hxx)
  • Mixing desk with at least 6 line-ins, one aux or sub out
  • linphone instances to connect to the pbx
  • asterisk with custom extensions and scripts
  • siptosis skype gateway

ESI u46xl

Linux has crappy support for this device. To initialize the device properly, send the following to the usb mixer with 'amixer -c 1 -s': 

cset numid=1 on,on
cset numid=2 on
cset numid=3 0,0,0,0
cset numid=4 on,on
cset numid=1 off,off
cset numid=5 off
cset numid=1 on,on
cset numid=7 on,on,on,on
cset numid=8 on
cset numid=6 0,0,0,0
cset numid=9 31,31,31,31,31,31

(yes, we turn 1 on, of and on again, needed to properly load 5, which disables monitor)

This .asoundrc makes the channels individually adressable and creates some fake input/output for linphone:

You need a sip.conf with a spy user and a feedback user, which both are in context spy.

You may want to create sip accounts for the panel members. Dump them in context panel.

You might want to make an extension 'panel' in your public sip context, which goes to panel|s|1.

And you will need something like this in your SkypeToSipAuth.props: 

*,sip:panel@pbx.sonologic.net:5060

Somehow it seems to dial the sip uri without registering, so panel must be in the public incoming SIP context.

Known issues

  • siptosis - spy output is very choppy, is this for all sip channels?? needs testing, spy works perfect when spying on iax channels
  • killing siptoskype without hanging up the incoming skype call will result in odd lingering channels in asterisk, messing with your head
