Our product capabilities
Call Security
Preventing fraud in the contact centre by identifying suspicious calls and authenticating legitimate customers before you answer. This enables you to divert potentially fraudulent calls to specialist teams and create a frictionless caller experience for genuine customers.
Call Management
Complete call management removes the risk of telecoms migrations and ensures you never miss a call again.

Call Recording
Recording calls for business best practice or compliance. Recordings are stored securely in the cloud for as long as you need, depending on your data retention policy, or to comply with regulations such as MiFID II, which require you to store recordings for seven years.
