Gateway Throttling Profiles

Gateway Throttling Profiles define rules for automatically disabling a Gateway when its error rate exceeds a configured threshold. When a gateway receives too many error responses within a time window, Yeti temporarily stops sending calls to it.

A throttling profile is assigned to a gateway via the Gateway configuration.

Id

Unique identifier.

Name

Name of the throttling profile.

Codes

The SIP disconnect codes that are counted toward the error threshold. Multiple codes can be selected. Available options:

Local 408

Local timeout — call attempt timed out on Yeti side before receiving any response.

SIP 408

Remote timeout — gateway responded with SIP 408 Request Timeout.

SIP 480

Temporarily Unavailable — gateway responded with SIP 480.

SIP 503

Service Unavailable — gateway responded with SIP 503.

Threshold Start

The error rate percentage (1–100) at which throttling begins. When the error rate rises above this value, the gateway starts being throttled (probability of sending calls to it begins to decrease).

Threshold End

The error rate percentage (1–100) at which the gateway is fully blocked (no calls sent). Must be greater than Threshold Start.

Window

The time window in seconds (1–120) over which the error rate is calculated.

Minimum Calls

The minimum number of call attempts required within the window before throttling logic activates. Prevents throttling on gateways with very low traffic.
