A categorised guide to the VoIP features that matter, from call routing to AI and reporting.
By the Telappliant team
Business VoIP has grown well beyond simply making and receiving calls over the internet. This guide groups the features that actually matter into categories, so you can compare providers on substance rather than a marketing checklist.

- Time-based routing for opening hours, lunch and out-of-hours
- Hunt groups and ring groups across teams

- Call forwarding, including conditional forwarding on no answer or busy
- Call parking and pickup between colleagues
Mobility and flexible working
- Softphone apps for desktop and mobile carrying the business number
- Call handoff between desk phone and mobile mid-call, without redialling

Choosing what actually matters for your business
Not every business needs all thirty-six of these. A ten-person professional services firm gets most of its value from mobility, voicemail-to-email and CRM integration, while a contact centre needs the full reporting, recording and AI stack. Match the feature list to how calls actually flow through your business rather than buying the biggest package available.
