Can I whitelist specific numbers?

Yes: suppliers, family, priority customers — you add their numbers to a whitelist and they never face the filter, whatever they say or whatever their history. Conversely, a blacklist permanently blocks known unwanted numbers, and both are managed from the dashboard in a few clicks. Whitelisted numbers can also get special treatment: a dedicated greeting script, their own urgency threshold, direct routing to you. It's your telephony — these rules are yours.
