Edesy keeps two separate lists. The inbound blocklist (/v1/blocked-callers) refuses calls from listed numbers to any number in your workspace, before any routing runs. The DNC list (/v1/dnc) stops your campaigns calling to listed numbers. Adding a number to one list does not affect the other.

	Inbound blocklist	DNC list
Stops	Calls from the number to you	Your campaign calls to the number
Applies to	Every inbound call in the workspace	Campaign contacts and leads
Endpoint	`/v1/blocked-callers`	`/v1/dnc`

Inbound blocklist#

Method	Path	Description
GET	`/v1/blocked-callers`	List blocked callers
POST	`/v1/blocked-callers`	Block a caller
DELETE	`/v1/blocked-callers/{id}`	Unblock

curl -X POST https://voice-api.edesy.in/v1/blocked-callers \
  -H "Authorization: Bearer $EDESY_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "phone_number": "+9198XXXXXXXX", "note": "Repeated spam calls" }'

Field	Type	Required	Description
`phone_number`	string	Required	4 to 20 characters. Numbers are normalised, so `+91 98...`, `098...` and `98...` match the same caller
`note`	string	Optional	Up to 200 characters

Blocked calls are refused before they are answered, so there is no talk-time charge.

DNC list#

Method	Path	Description
GET	`/v1/dnc`	List entries
POST	`/v1/dnc`	Add numbers
DELETE	`/v1/dnc/{id}`	Remove an entry

curl -X POST https://voice-api.edesy.in/v1/dnc \
  -H "Authorization: Bearer $EDESY_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "phone_numbers": ["+9198XXXXXXXX", "+9197XXXXXXXX"], "reason": "opt_out", "source": "agent_disposition", "notes": "Asked not to be called" }'

Field	Type	Description
`phone_numbers`	array	Numbers to add
`reason`	string	`opt_out`, `complaint`, `registry` or `manual`
`source`, `notes`	string	Your own context

{ "data": { "added": 2, "already_present": 0, "invalid": 0, "invalid_samples": [] } }

Entries marked global: true are platform-wide suppressions. You can see them but not remove them.

When contacts or leads are added to a campaign, DNC numbers are counted as suppressed_dnc and never dialed. See AMD, Fallback Caller ID and DNC.
