docksterisk

What is it?

It's a starting point to a containerized Asterisk SIP server. It includes mimimalistic extensions and dialplan configurations. It's using Asterisk 14 and PJSIP instead of CHAN_SIP.

I primarily created docksterisk for my own use but feel free to use it, or part of it, for your own SIP server.

What is it not?

• No UI
• Not Asterisk-noob-friendly
• Not Docker-noob-friendly
• No documentation
• No support

What is it based on?

Generally this is based on:

• Docker
• phusion/baseimage
• Asterisk 14

What does it include?

• A docker-compose to build/run the image/container
• Shows how to use the PJSIP wizard for easier extension and trunk configuration
• A minimalistic dialplan
• Multilingual GoogleTTS (Text To Speech) AGI, dial extension 300 for a demo
• Shows how to use a telemarketers blacklist to ban calls
• Shows how to use iptables on the host against script kiddie scans
• Asterisk log messages forwarded to Docker-logs

Additional information

• Since large port ranges in Docker (in combination with iptables) are problematic, I'm exposing the host network to the Docksterisk container
• Ports used: 5060/udp (SIP), 8088/tcp (HTTP), 16384-17000/udp (RTP)
• The configuration samples assume that the SIP phones are behind NAT and the SIP server is on a public, static IP (i.e. on a VPS)
• If you want to use the built-in webserver for uptime monitoring, you can use this URL: http://mysipserver:8088/docksterisk/httpstatus/
