A guide on voice agent function calling that covers direct answering capability, latency tolerance thresholds from a 2013 study, function selection accuracy decline with increasing tool count, and fixed two-hour session limits including warning and error signals.

Function calling allows a voice agent to directly answer questions like 'Where’s my order?' rather than transferring the caller to a human agent.

Originalauszug
The HumanMCP study measured a drop from 98% at 10 tools to 88% at 100.
When the toolset grows, selection accuracy falls. Add functions one at a time and re-check selection accuracy after each. One lookup, three failure lines, and a filler function make a complete first release.

Function calling is how a voice agent answers "where's my order?" instead of transferring the caller to someone who can.
One order-status lookup on the inbound telephony agent pattern takes two round trips, three function calls, and a spoken line for every way it can fail.
Originalauszug
Ratings of perceived willingness drop off noticeably at 600ms in the classic 2013 gap-tolerance study from Roberts and Francis, and the difference turns statistically significant between 700 and 800ms.
Dead air is what the caller hears while your handler works, and it costs you fast. InjectAgentMessage is what covers that silence in the reference pattern.

Yes, at two hours, and an in-flight lookup won't hold the session open. You get a Warning with MAXIMUM_SESSION_LENGTH_APPROACHING at 1 hour 55 minutes, then an Error with MAXIMUM_SESSION_LENGTH_REACHED at the two-hour limit .
KeepAlive doesn't extend it, and the docs don't cover a pending FunctionCallRequest at close. Finish or abandon it, then reconnect with agent.context .
