Conference Software Architecture Roles

[conn]

Am I supposed to, perhaps, input some arguments there?

It seems there is a bash script sitting in front of the actual sup escript that is failing to pass along the command line args properly. I'm looking into it.

Bypass-able thusly:

/opt/kazoo/bin/kazoo escript lib/sup-4.2.28/priv/sup.escript -?
Usage: sup [-?] [-n [<node>]] [-c [<cookie>]] [-t [<timeout>]] [-v]
           [<module>] [<function>] [args ...]

  -?, --help     Show the program options
  -n, --node     Node name [default: kazoo_apps]
  -c, --cookie   Erlang cookie [default: change_me]
  -t, --timeout  Command timeout [default: 0]
  -v, --verbose  Be verbose
  <module>       The name of the remote module
  <function>     The name of the remote module's function

But I'm working on a fix for the bash script sitting in front of this invocation

Oh, okay.

In the guide - https://docs.2600hz.com/sysadmin/doc/install/install_via_centos7/ - where says things like:

echo "ip.add.re.ss aio.kazoo.com aio" >> /etc/hosts

Can I just leave the `aio.kazoo.com aio` parts, or am I supposed to change them? So, I do `subdomain.mydomain.net subdomain`?

It needs to match your hostname.

How do I resolve this?

Looks like you're running out of system memory (RAM).

Which specs does the server are you using have?

Hmm...

 

I was using dihgitaloceans cheapest droplet. 1 GB of RAM.

I have finished the setup here: https://docs.2600hz.com/sysadmin/doc/install/install_via_centos7/

I have looked around, but I confused where to start with my goal I first mentioned I wanted to do.

First off, how do "calls" even work here? How can I have two numbers call each other? What do I need to learn to understand that bit.

I understand what callflows are.

Where would I start to make an all voice conference service, where, like IRC, you have multiple rooms and you have an endpoint like a website where users say, click on the room they want to enter and enter a conference that is open all the time to any number of people at the same time?

 

[mc_]

There is a simplistic quickstart guide that will show you some basic API commands.

Endpoints dial numbers, some endpoints carry around a caller ID so you "know" who is calling. Numbers are assigned to callflows which determine what to do with the caller - put them in a conference, connect them other endpoints, play a recording, put the caller in a conference, etc.

Triggering calls from a website typically requires using Click-To-Call. You can also front the request with your own server and call the conference dial command from your server.

Is there a shell script that automates everything here: https://docs.2600hz.com/sysadmin/doc/install/install_via_centos7/

To really clear things up for myself, I would like to know if this software is really suitable for my use case. Much of what I have seen it be used as is as internal phone systems. Office phones, and whatever. I guess my use case is essentially a "Discord Voice Channel". I guess this software could be used for that, but am I overcomplicating things by using this for voice channels that would be used via apps for Android devices?
