# Telephony integrations for Bolna voice AI agents

> Connect Twilio, Plivo, Exotel, Vobiz or your own SIP trunk to Bolna to make and receive Voice AI calls on your own phone numbers.

Connect a telephony account to place and receive calls on your own phone numbers. All providers below support inbound and outbound calls with Bolna agents, and let you bring your own account.

Setup guides for each provider live in **Voice Agents → Deploy → Telephony providers**, next to phone numbers, inbound calls and outbound calls, because connecting telephony is part of deploying an agent.
