Preview
Your reps only ever pick up the phone to someone who already said yes.
LeadsLiner is a voice-agent platform that makes and takes phone calls. It was built from scratch on Telnyx Call Control, with its own audio bridge, so it owns the parts that other platforms hide: who the call comes from, when it can be interrupted, and when it hands over to a person.
An agent greets the person, qualifies them, and warm-transfers to a human rep the moment they say yes. It detects voicemail and phone menus, and every call is recorded, costed and reviewable.
