Owner asked for total minutes, call time and missed calls in one place, and the money left on
voip.ms. Reports now totals answered calls, talk time and outside minutes (in from arrival, out
from the answer: roughly what the provider bills), charts outside minutes per day, and shows each
voip.ms trunk's balance (getBalance; verify with a real account).
integrations/voipms/client.ts: voipmsApi(url, creds, method, params)
per 06 §5.1 (GET rest.php, 15 s timeout, status "success" or an error
code). The API password is only in the query string: never logged,
never in an error. Known codes get a message for people
(invalid_credentials, ip_not_enabled, ...). getServers and getDids
parse forgivingly; no_did is an empty list.
Routes: GET /api/trunks/:id/voipms-servers, GET and POST
/api/trunks/:id/import-dids. Import adds only numbers voip.ms lists
and that aren't added yet, label from the description, destination
hangup. 400 without API credentials, 502 provider_error with voip.ms's
reason. VOIPMS_API_URL overrides the endpoint for tests.
Web: the trunk form's server list comes from voip.ms once the trunk
has API access, falling back to the built-in list with the reason.
"Import numbers from voip.ms" sits in the trunk form's API section and
the setup wizard's numbers step. Saving a new API password asks
voip.ms again (found in e2e: the old error stayed).
The response shapes are from the 06 spec, not a real account: voip.ms's
API docs need a login. Marked TODO(spec) and (verify) in 06. Tests use
a fake rest.php; e2e m9-t1 too (trunk created off, so nothing registers
to the real voip.ms).
