Does an AI sales agent improve with more calls? Only with outcome labels. Worked maths: 13,791 leads per arm to tell 2% from 2.5%, plus a feedback-signal table.
Is AI cold calling legal in the UK? PECR reg 19 vs reg 21, TPS and CTPS screening, the ICO avatar fine and the unresolved live-speech question, in one table.
Twilio records AI calls at $0.0025 a minute, then bills $0.0005 a minute each month to store them, so storage passes capture after five months. Worked tables.
Your AI voice agent needs the caller’s number before it speaks. LiveKit SIP attributes, Twilio Media Streams parameters and Pipecat, with every limit checked.
My AI voice agent says the same thing twice: test whether callers heard it or only the log shows it. 11 LiveKit and Pipecat cases, fixes checked 24 Sep 2026.
How long Twilio takes to approve a UK or Australian KYC bundle: three published windows, a day-by-day timeline, and fixes for all 21 listed rejection reasons.
AI SDR vendors bill per seat, contact researched, message sent or credit, and the units do not convert. Worked sums at 2,000 contacts from nine pricing pages.
A vendor language count proves generation, not parity. Run 12 probes in English and your target language, score the delta, then apply the ship-or-hold gate.
A subcontractor who never answers in Procore may never have activated the account. Diagnose it with the Four-Door Test, an escalation ladder and the NSW clock.
