Add an AI voice agent to the phone system you already have
Most “AI voice” vendors want to replace your phone system. We don’t.
dOpenSource is a team of SIP and VoIP engineers. We build AI voice agents that plug directly into your existing SIP infrastructure — Asterisk, FreeSWITCH, Kamailio, OpenSIPS, or any SIP-compatible PBX — so you get 24/7 automated call handling without ripping out what already works or locking yourself into a proprietary platform.
If your callers currently hit voicemail after hours, wait on hold for questions you answer fifty times a day, or get lost in a menu tree, an AI voice agent fixes that in about a week.
Why dOpenSource?
We’re phone system engineers first, AI integrators second. Anyone can wire up a chatbot with a voice. Making it behave reliably on a live SIP trunk — clean call routing, no dropped transfers, proper failover to a human — is the part that actually breaks. That’s the part we’ve been doing for years.
Open-source native. We work in the open-source telephony stack every day. No black-box platform, no per-minute markup you can’t audit, no vendor lock-in. You keep control of your own infrastructure.
