Assignment & Provisioning

Assignment & provisioning in Callroute is designed to make number administration fast, accurate and scalable.

Every number is easy to find using tags, descriptions, locations and status — including whether it’s reserved or quarantined — so you’re not relying on spreadsheets or outdated tracking.

Once you’ve found the right number, you can assign it to the user or service of your choice in just a couple of clicks.

This makes day-to-day changes simple and predictable, even across large and multi-region estates.

Call Handling & Resilience

Callroute makes it effortless to route phone numbers to the service of your choice — Microsoft Teams, Webex, existing PBXs, contact centres and more. Assign individual numbers or update entire ranges in bulk in just a few clicks.

Behind the scenes, Callroute intelligently routes calls across the Callroute network wherever possible.

That means if one Callroute-connected number calls another, the call stays on-net — avoiding unnecessary PSTN breakout and delivering better quality, lower cost and higher resilience, regardless of the platforms in use

Grouping & Organisation

Managing numbers in spreadsheets or across multiple provider portals makes it hard to stay organised and consistent.

As environments grow, visibility is lost and even simple changes become harder to manage.

Callroute brings all numbers into one place and lets you organise them using business-defined structures — such as custom locations, tags, descriptions and reservations.

The result is a clear, always up-to-date view of your numbering estate, plus powerful search capabilities that make it easy to find and manage numbers at scale.
