Platform matrix

All twelve platforms side by side: channel, audio, timestamps, delivery, retries.

12 systems we read conversations from, and what each one gives us. The left column is the adapter name, which is the word that goes in your webhook URL. Each platform also has a page of its own

bolna	voice · audio · second timestamps · webhook · retries
crisp	chat · audio · millisecond timestamps · polled by us · no retries
elevenlabs	voice · audio · second timestamps · webhook · retries
gupshup	chat · no audio · millisecond timestamps · webhook · retries
intercom	chat · no audio · second timestamps · polled by us · no retries
messenger	chat · audio · millisecond timestamps · webhook · retries
retell	voice · audio · millisecond timestamps · webhook · retries
sunco	chat · no audio · millisecond timestamps · webhook · retries
twilio	chat · audio · second timestamps · webhook · retries
vapi	voice · audio · millisecond timestamps · webhook · retries
wati	chat · no audio · second timestamps · webhook · retries
whatsapp_cloud	chat · audio · second timestamps · webhook · retries

What the words mean

voice, chat	Whether the platform carries calls, typed messages, or both.
audio	The platform hands us the recording, so a score can rest on how something was said and not only on what the transcript holds.
millisecond, second timestamps	How finely the platform times a turn. Seconds are enough for a reply time and too coarse to order two turns that landed in the same second.
webhook, polled by us	A webhook platform pushes each conversation to us as it finishes. A polled one is read on a schedule, so it arrives minutes later.
retries	Whether the platform sends a delivery again after a failure. Where it does not, a delivery we miss is gone, so an import fills the gap.

The generic contract is not on this list. It is the shape you post from a stack of your own, not a platform we read, and it has its own page.
