SIP-Native, PBX-Ready

Connect Like Any SIP Phone

Our voice agent registers over SIP as an internal extension. Open firewalls, point your PBX at it, and use the web UI—designed to feel like the admin interface of a SIP phone your team already knows.

Works with any SIP-compliant PBX. No vendor lock-in—use the hosted provider or platform you already resell.

Connect Like Any SIP Phone

Choose Voice & LLM, Add Your Tools

Quick Setup, Your Integrations

Pick voice and LLM providers in the UI and spin up a new agent in minutes. Add your own tools and integrations, or deploy with auto-provisioning: host XML configs on your existing SIP phone provisioning server so the agent configures at boot.

Select voice and LLM providers in the interface. No coding required to get a new voice agent live.

Quick Setup, Your Integrations

Receptionist Tools Built In

Internal Extension, Full PBX Features

Because the agent is a SIP extension on your PBX, it can do what receptionists do: internal transfers, 3-way conferences, paging, and other basic telephony. All without custom integration—it just works with your existing PBX.

Transfer callers to the right department or person. The agent lives on your PBX like any other extension.

Internal Extension, Full PBX Features

Any PBX, Any Provider, Worldwide

One Agent, Every SIP PBX

Our agent speaks standard SIP. It connects to any PBX that conforms to the protocol—no matter which hosted PBX provider you use or resell. The market is global: ITSPs and MSPs can offer voice AI to their customers everywhere.

SIP is the standard. No proprietary tie-in. Connect to any SIP-compliant PBX and switch providers if you need to.
