Edesy SIP trunking connects your PBX or AI voice-agent platform to the Indian phone network. A termination trunk gives you a SIP host to dial out through, and any Edesy number can send its inbound calls to a SIP URI you choose. Calls cost Rs 0.50 per minute with a 60-second pulse, and unanswered calls are free.
Ready to connect? Sign in at voice-app.edesy.in, create a trunk under SIP, and place a test call from the trunk page. See the Quick Start.
