Question 1

How does an Edesy SIP trunk power pstn connectivity?

Accepted Answer

The missing telephony layer between your AI voice agent and the Indian public phone network. Edesy handles SIP signalling, media, DTMF and G.711 codecs so your agent can make and receive real phone calls. If your agent does not speak SIP, use a raw audio WebSocket or the text-based Conversation Relay instead.

Question 2

Which AI voice-agent platforms support pstn connectivity?

Accepted Answer

There are quickstarts for LiveKit Cloud, Vapi, Retell, Bolna, xAI Grok and Dograh. Pipecat connects over WebSocket media streams, and any other SIP-capable stack, such as Synthflow, can use the generic SIP setup.

Question 3

What is a SIP trunk for an AI voice agent?

Accepted Answer

A SIP trunk is the telephony layer that connects your AI voice agent to the public phone network. Platforms like Vapi, Retell, LiveKit, Bolna, xAI Grok and Dograh run the conversation, but they need a SIP trunk and phone numbers to make and receive calls. Edesy provides that trunk plus Indian DID numbers.

Question 4

What is BYOC and how does it work with my voice-AI platform?

Accepted Answer

BYOC (Bring Your Own Carrier) lets you plug Edesy in as the telephony provider for your AI voice-agent platform. You add your Edesy trunk's SIP host (port 5070) and credentials, or allowlist the platform's IP, inside Vapi, Retell, LiveKit or similar, then route an Indian DID to the agent. Indian minutes are then billed in INR by Edesy.

Question 5

Which AI voice-agent platforms does Edesy work with?

Accepted Answer

There are quickstarts for LiveKit Cloud, Vapi, Retell, Bolna, xAI Grok and Dograh, and a Pipecat sample for WebSocket media streams. Any other platform that can dial a SIP trunk or answer a SIP URI, such as Synthflow, can use the generic SIP setup.
