Engineering notes and product updates from the team building Bolna’s voice AI infrastructure.
Why a single voice AI call rarely closes the loop, how Bolna Workflows give every call outcome a next step with retries, waits, extraction, API calls and WhatsApp follow-ups, and how to build your first one.
How Graph Agents work on Bolna, from nodes, transitions and routing order to per-node control, where they fit, and a step-by-step guide to building your first one.
Voice agents break when one long prompt has to carry every step of a call. Graph Agents split the call into nodes with one job each, an idea seventy years in the making. Here is where it came from.
Our Datastream to BigQuery pipeline was delivering call data 5-15 minutes late and the bill kept climbing. Moving analytics to ClickHouse Cloud, and writing less data in the first place, made call data real time and cut costs to roughly a sixth.
TypeSafe's Jev is pitched at exactly the decisions that sit around a phone call. We put it on three real jobs against 17 models: it is 1.7 to 3.3 times faster everywhere, level with the best on judging and extraction, and not ready for routing.
Customers wanted to drop a Bolna agent onto their website. We budgeted five to six weeks, had a proof of concept in two, and shipped in about three - by reusing the telephony stack we already ran.
How the Bolna engineering team cut TCP connections across their WebSocket server fleet by hundreds per pod, without adding a single server.
Our real-time voice service containers were using too much memory and restarting mid-call. Two fixes: preloading workers and copy-on-write sharing.
When a single provider combo fails, thousands of calls can suffer at once. Here's how Bolna built monitoring that catches it in 30 minutes.
