What is Telephony?
2 min read · Bolcho
The plumbing that connects a voice agent to actual phone calls — numbers, carriers, SIP trunks, and call routing.
Telephony explained
Telephony is what turns a voice model into a working phone agent: buying or porting a number, connecting a carrier, routing inbound calls, and dialing outbound. In India it also means DLT/TRAI compliance and KYC.

Why it matters for voice AI in India
Understanding telephony helps you build voice agents that actually work for Indian callers, genuine languages, low latency, and near-cost pricing. Bolcho is built around exactly these fundamentals.
