Signals

Signals is a solution for detecting and blocking artificially generated traffic.

Each mobile device has a unique identifier assigned to it. It's called a Mobile Station International Subscriber Directory Number.

Use this API to create a list of trusted MSISDNs and add/remove numbers from it.

Numbers added to a MSISDN list are excluded from blocking.

Add phone numbers to a MSISDN list of trusted numbers so that Signals never blocks messages sent to these numbers.

Remove phone numbers from a MSISDN list of trusted phone numbers.

Check whether a phone number exists on a MSISDN list of trusted phone numbers.
