Authorizations

​
Authorization
string
header
required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Path Parameters

​
call_control_id
string
required

Unique identifier and token for controlling the call

Body

application/json

Start noise suppression request

​
client_state
string

Use this field to add state to every subsequent webhook. It must be a valid Base-64 encoded string.

Example:

"aGF2ZSBhIG5pY2UgZGF5ID1d"

​
command_id
string

Use this field to avoid duplicate commands. Telnyx will ignore any command with the same command_id for the same call_control_id.

Available options:
inbound,
outbound,
both
Example:

"outbound"

​
noise_suppression_engine
enum<string>
default:Denoiser

The engine to use for noise suppression. For backward compatibility, engines A, B, C, and D are also supported, but are deprecated: A - Denoiser B - DeepFilterNet C - Krisp D - AiCoustics

Available options:
Denoiser,
DeepFilterNet,
Krisp,
AiCoustics,
aic_l_quail,
