Everything your AI agent needs to reach the Indian PSTN

BYOC Termination Trunk

Configure our SIP URI and credentials as your Bring Your Own Carrier on Vapi, Retell, LiveKit, and more. Standards-based SIP, no lock-in.

Low-Latency Media Path

India-local PoPs keep the media path under 200ms so your AI agent's turn-taking stays natural and ASR/TTS accuracy holds up.

Indian DID Numbers

Provision local +91 DID numbers from our inventory at Rs 499/month and attach them to any SIP-capable voice agent in minutes.

50 Paisa Per Minute

Per-second INR billing at Rs 0.50/min keeps AI voice-agent economics predictable, with no forex markup on Indian traffic.

Inbound & Outbound PSTN

Full SIP signaling, media relay, DTMF, and codec negotiation for both inbound receptionist and outbound AI SDR use cases.

Works With Any Voice-AI Stack

Vapi, Retell, LiveKit, Bolna, Pipecat, Synthflow, or any SIP-capable agent. If it speaks SIP, it connects to Edesy.

TLS/SRTP Encryption

Secure signaling with TLS and media with SRTP. Compliance-ready connectivity for regulated Indian voice deployments.

India-Based Support

India-first onboarding, KYC, and support. Get your trunk and DID live without US-timezone ticket queues.

Trusted by Voice-AI Builders

See what AI voice-agent teams say

"We were burning USD on Twilio to give our Vapi agent an Indian number. Switching to Edesy BYOC dropped our per-minute cost to 50 paisa and media latency to Indian callers noticeably improved."

F

Founder

"Configured the Edesy SIP URI as our Retell carrier in an afternoon. Indian DID inventory and per-second billing made the unit economics for our AI SDR finally work."

C

CTO

"For our Hindi voice agent on LiveKit, the India-local PoPs kept jitter low and ASR accuracy high. The termination trunk just worked with LiveKit's SIP inbound and outbound."
