Deep Telephony Learning Path

Prepare yourself for Deep Telephony Tech.

Telephony is built from several layers, technologies and sources of information. You do not need to learn everything at once. The steps below guide you through the stack in a practical order and show you where to go deeper.

It is not just us. The learning path brings together open-source projects, documentation, telecom platforms and practical implementation experience. Follow each source for deeper information.
01
Understand the telecom base Asterisk and PBX fundamentals first.
02
Connect the infrastructure Trunks, GSM, routing, NAT and media.
03
Add the application layer Bring MYLINEHUB into the working stack.
AI Calling Demo

Experience AI calling on your own infrastructure.

Request an on-premise AI calling demo configured around your requirement. We can prepare the telephony and AI calling flow on your infrastructure so your team can experience how it works in its own environment.

Approx. ā‚¹10,000 setup charges

Final charges depend on the required call flow, infrastructure, integrations and configuration. More involved requirements may exceed ā‚¹10,000.

Your Learning Path

Learn the stack. Then build it yourself.

Start with Asterisk, move through PBX configuration and telecom connectivity, understand networking and media flow, then connect MYLINEHUB on top.

01

Learn the Asterisk Base Layer

Start with the telecom engine so everything above it makes practical sense.

Start with Asterisk Tutorials (Recommended For Beginners)

Many beginner tutorials online are based on legacy SIP (chan_sip). MYLINEHUB documentation is aligned with modern PJSIP architecture, helping you move from basic PBX learning to real production telecom deployments.

02

Configure FreePBX Properly

Move into extensions, trunks, IVR, queues and business-ready PBX configuration.

FreePBX Series (UI-Based Asterisk Control)

If you donā€™t want to write dialplan or manage raw Asterisk configs, FreePBX lets you control your PBX through a UI. These tutorials are written for FreePBX 16/17 with PJSIP (modern SIP), and every guide includes step-by-step screenshots so you can configure safely.

Recommended routing order: Trunks ā†’ Inbound Routes ā†’ Outbound Routes (so calls can enter, route correctly, and exit).
