Asterisk Scale Experimentations

How to start

docker-compose up -V

This will start :

• Asterisk
• Kamailio
• Consul
• Nginx (aka api-gateway)
• Rabbitmq
• The Text-to-Speech demo app
• The Conference demo app

How to test

SIP registration :

• username: demo
• password: demo

Text-to-Speech

Once registered you can call the number 8001, you should hear which asterisk you are connected to. This is the demo App which answers to the call and play the sound.

Calling the number 8001 multiple times you should hear different Asterisk IDs.

Conference

Once registered you can call the number 7001, you will be placed in a conference room whatever Asterisk you will be connected to.

How to scale

docker-compose scale asterisk=2
