Yeah, its a pretty straightforward setup of pointing DNS to your HAProxy instead of Crossbar, configuring it with the SSL certs, and setting up the backends with your Crossbar instances. Any HAProxy guide should do the trick.
Got it. Thanks a ton!

You just need to get the cert in the right location. Honestly HAProxy fronting it is probably a better solution anyway, since you can load balance among servers running Crossbar, stay up-to-date on the encryption/cipher suites better, etc.
Interesting. So, do you guys have any tutorials for the HAProxy option? Or is this just something I have to "go google"?

Single-server installs are proofs of concept, for testing/instructive purposes, do not use in production, here be dragons!
There are two common "minimal" installations:
- 2 zones, 4 servers per zone - in each zone, 2 bigcouch servers, 1 kazoo/kamailio/rabbit, 1 FreeSWITCH
- 1 zone, 7 servers - 3 bigcouch servers, 2 kazoo/kamailio/rabbit, 2 FreeSWITCH
But the big one is to have 3+ servers for bigcouch from the start.
Is there a tutorial for the (2 zones, 4 servers per zone - in each zone, 2 bigcouch servers, 1 kazoo/kamailio/rabbit, 1 FreeSWITCH) server?

There's a page from a while ago: https://docs.2600hz.com/dev/applications/crossbar/doc/securing_crossbar/
It shows setting up a self-signed certificate but you can just skip to where the guide configures Crossbar. Should work as expected once you restart Crossbar.
Another option is to use HAProxy or similar in front of Crossbar to handle SSL termination.
Does that mean I cannot use something like Godaddy's Godaddy EV SSL Certificates?

Hello,
Right now I only have a single server setup: https://docs.2600hz.com/sysadmin/doc/install/install_via_centos7/
I am using cloud services such as digitalocean. I was wondering how I might go about scaling up servers as slowly as I need and if needed scale down -so that I might be able to automate the scaling to save money. Any guidance that could be provided would be much appreciated.

Hello,
I am familiar with setting up a server and am using Digitalocean to do so: https://docs.2600hz.com/sysadmin/doc/install/install_via_centos7/
I was just wondering about setting up SSL with it. Would a Godaddy Extended Domain & Business Validation (EV) certificate work?

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?

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

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?

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.

Is this comment up to date:
# Add 2600Hz RPM server # You can find the latest Release RPM here: https://packages.2600hz.com/centos/7/stable/2600hz-release/ # Currently, 4.2 is considered 'stable' so: # https://packages.2600hz.com/centos/7/stable/2600hz-release/4.2/2600hz-release-4.2-0.el7.centos.noarch.rpm -
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/hostsCan I just leave the `aio.kazoo.com aio` parts, or am I supposed to change them? So, I do `subdomain.mydomain.net subdomain`?

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:

Oh, okay.

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

The server config shows you how to prefer querying database nodes in the same kazoo zone and using the other zone as a failover (hopefully minimizing WAN latency). Since couch is multi-master, even if the data isn't on a given node, the handling node knows how to retrieve it from its peers.
Each db server will have its own hostname; any on the same LAN (typically) should be in the primary list and any that live across a WAN would include the 'backup' signifier.
I think I might be starting to understand. So, I am using a digitalocean droplet -Centos 7- for this project. To set up these zones to Bigcouch, would it be sufficient to just keep making subdomains for the two zones via the digitalocean admin?

You should edit the DB servers in that file, after "balance roundrobin". Change to your CouchDB server info.
What does this all mean:
server db1.zone1.mydomain.com 127.0.0.1:5984 check server db2.zone1.mydomain.com 127.0.0.2:5984 check server db3.zone2.mydomain.com 127.0.0.3:5984 check backup server db4.zone2.mydomain.com 127.0.0.4:5984 check backupShould I simply give the subdomain from the output of:
kazoo-bigcouch statuswhich is
bigcouch@subdomain.example.netso just replace the first two with
subdomain.example.net?

Okay. Thank you.

I am now on the HAProxy part. It does not really give much guidance on what to put into the file it wants me to edit. All it says is:
# Edit /etc/kazoo/haproxy/haproxy.cfg to setup the backend server to point to BigCouchNow, after some googling, I found this: https://github.com/2600hz/kazoo-configs-haproxy/blob/master/haproxy/haproxy.cfg
It looks like an official enough source, so that part should be covered. However, should I use what is in that file from the git repo linked above? Or should I use something else?

If there are no FreeSWITCH servers yet, you are correct that the destination sets should be empty.
When you setup FreeSWITCH and ecallmgr, there's a heartbeat that Kamailio will receive and auto-add FreeSWITCH to the proper destination set.
Got it, thanks for the explanation.
-
So, I finished going through the kazoo-kamailio setup in the official docks and ran:
kazoo-kamailio statusand I got:
error: 500 - No Destination SetsIs that an acceptable response to where I am at in the setup at this moment -i.e, it will change once I finish entire setup? or does it indicate that I did something wrong at this stage?

Hmm ... thanks for the advice. I understand completely what you are saying :-)
How much people would a conference support for cluster setup?
in 2600Hz Mobile

Based on this discussion:
I am interested in knowing how, for example, the 7 servers per single setup mentioned in the discussion above, many people such a cluster can handle if all that we are looking for is conferencing for many people. If we were using a VPS from AWS, linode, Google, or Digitalocean, what specs for the machines should we look at to get support for say, 10,000 people per conference?
