Real situations
When teams bring us in on Twilio
Some calls never happen
Calls fail quietly, and the first sign is a customer complaining.
What we doWe add retries and alerts so failures are seen the same day.
Error 11200 keeps appearing
Twilio cannot reach your webhook in time, so calls drop or behave oddly.
What we doWe fix the webhook endpoints and monitor their response times.
The monthly bill keeps growing
Usage rises every month and nobody can say which flows are driving it.
What we doWe break usage down by number and flow and cut what is wasted.

Questions
Twilio management — common questions
How many calls per second can Twilio place?
By default each Twilio account can create 1 outbound call per second through the API. Customers with an approved business profile can raise it themselves in the Console’s voice settings.
What happens to Twilio calls above the CPS limit?
API requests for calls over the limit are queued and placed as capacity becomes available, so bursts turn into delays rather than errors.
What does Twilio error 11200 mean?
Twilio could not get a valid response from your webhook URL — it returned an error status, the connection failed, or the response took too long or could not be parsed.
Does Twilio’s CPS limit apply to inbound calls?
No. The calls-per-second limit applies to calls created through the API, not to inbound calls or outgoing <Dial> calls.
How much does Twilio management cost?
From $100 a month. The exact price depends on users, volume and what needs setting up, and you get it in writing within 2 working days, without giving us access.
Is there a minimum term?
No. It is month to month with 30 days’ notice.
