BYOC SIP Trunk

Six Platform Quickstarts

Indian DID Numbers

The short answer

To put an AI voice agent on an Indian phone number, create an Edesy termination trunk for outbound calls and route an Edesy DID to your agent's SIP address for inbound calls. Dashboard quickstarts cover LiveKit Cloud, Vapi, Retell, Bolna, xAI Grok and Dograh; Pipecat connects over media streams. Calls cost Rs 0.50/min with a 60-second pulse.

Follow the quickstart in the Edesy dashboard or the docs for exact values.

Telephony Infrastructure for Voice AI

What your AI agent needs to reach the Indian phone network

BYOC Termination Trunk

Add your trunk's SIP host (port 5070) and credentials, or allowlist your platform's IPs, as the carrier in Vapi, Retell, LiveKit or Dograh. Standard SIP, no lock-in.

Indian DID Numbers

Buy +91 mobile (Rs 499/mo), landline (Rs 449/mo) or toll-free (Rs 999/mo) numbers after KYC and route each one to your agent.

Rs 0.50 Per Minute

Calls are billed in 60-second pulses at Rs 0.50/min from a prepaid INR wallet. Unanswered calls are free, which helps outbound dialers.

Inbound SIP Destinations

Save your agent's SIP address in an address book, press test call, then point any number at it.

Platform Quickstarts

Quickstarts for LiveKit Cloud, Vapi, Retell, Bolna, xAI Grok and Dograh, plus a generic setup for any SIP-capable stack.

Media Streams for Pipecat

No SIP on your side? Stream raw L16 PCM audio at 8 or 16 kHz to your WebSocket. A Pipecat sample serializer is available.

Conversation Relay

If your bot works in text, Edesy handles speech-to-text, text-to-speech, barge-in and DTMF over a Twilio ConversationRelay-compatible WebSocket.

Auth and Encryption

IP/CIDR allowlist or digest credentials with password rotation. SIP TLS + SRTP is available on request.
