Calling, numbers & call routing
How this is scored
What the phone system does with a call: local geographic numbers in the customer's own area code and in other countries, number blocks and porting of existing numbers, extensions, IVR menus, queues, ring groups and hunt groups, time-based and holiday routing, call forwarding and transfer, voicemail to email, fax to email, conference calls, call recording, call park and pickup, busy lamp fields, caller ID per user or team, and emergency calls (110 and 112) with the caller's location.
0 — Places no phone calls on the public telephone network; a chat or meeting tool with internal calling only.
3 — Phone numbers and extensions with forwarding and voicemail; IVR, queues, time-based routing and porting are basic or not described.
5 — Local numbers in the customer's area code with porting documented, IVR menus, queues and ring groups, time-based and holiday routing, voicemail to email, call transfer and pickup, call recording, fax or fax to email, and emergency calling described.
8 — Number blocks and international numbers in many countries, a visual call flow editor, skills or priority routing, call park and busy lamp fields, recording rules per user or queue with consent announcements, emergency calls with a registered location per user or site, and the porting process and its timelines documented.
10 — Call handling a large multi-site company runs on: every feature above with number provisioning and porting by API, routing by caller data from the CRM, location-aware emergency calling for home offices, and the full feature set documented per plan with its limits.
The IT Administrator
Multi-level auto attendants, call queues with automatic distribution and overflow rules, business-hours routing by time zone, blind and warm transfer, call park, voicemail with transcription, recording, online fax and number porting are all documented, with local, toll-free and national numbers across dozens of countries including Germany. Emergency calling is documented down to registered locations per user, a prompt when calling from an unregistered location, and routing to a 24/7 emergency call centre when no address is detected. We found no public information on porting timelines, number blocks or a visual call-flow editor. 3 11 12 19
