Virtual hold/callback lets callers opt out of waiting on hold and receive an automatic return call when an agent becomes available.
3. What is a 'unified agent desktop' in the context of a CTI-integrated contact center?

Hosted cloud models convert large upfront hardware costs (CapEx) into predictable recurring operational expenses (OpEx).

DNIS identifies which number the caller dialed, allowing the ACD to apply different routing rules for different advertised numbers.
