Operating contract
The call-back list: inbound calls nobody answered, newest first, each saying whether the caller left a voicemail and how long it runs.
This is a NARROWER comms.list_calls and it exists as its own capability for the same reason Quo's own MCP server added one — 'who did we miss' is a question a shop asks by name, every morning, and making a model compose it out of two filters is how it gets composed wrong.
OUTBOUND CALLS ARE NEVER INCLUDED, whatever their status: a call the shop placed that failed to connect is a dialling problem, not somebody waiting to hear back.
has_voicemail splits the list into two different jobs. A missed call with a voicemail has a message to read first (comms.get_call_recording with kind: voicemail, or comms.get_call_transcript). A missed call without one is a cold call-back, and the customer record behind customer_id is all the context there is.
TRUNCATION: total is how many missed calls match the window and omitted how many are not in this response. When omitted is not 0, call again with offset set to next_offset.
Who may call it
- Permission
calls.accessThe caller must hold Calls at the ACT level. A read-only dashboard grant on the same section is refused.- Plan
- Every planNo plan gate. Available on every Service VIN plan.
- Retries
naturalNaturally idempotent — running it twice leaves the same world as running it once. A retrying integration needs no key.- Rate class
readCounted against the read budget — the widest of the four.
Partial answers
omitted is how many matching records are not in the response, and 0 is a real answer meaning you have all of them. Continue with next_offset.

The four gates run in this order on every surface, and the order is not arbitrary — see Authentication.
| Status | Code | When |
|---|---|---|
| 404 | not_found | The id is unknown, or the feature is not enabled for this account. Deliberately the same answer for both. |
| 403 | forbidden | This login does not hold calls.access. |
| 422 | validation_error | An argument was wrong. The message names the field. |
| 429 | rate_limited | Too many read calls. Back off and retry. |
| 500 | internal_error | Something failed on our side. Nothing was changed. |
