  • “We implemented Callroute … as a replacement for our legacy telephony system, which had a number of limitations and no integration with MS Teams. The experience with Callroute has been very positive. The Teams integration has been seamless, the reporting is robust, and the portal is easy to use…we now have far better control over call routing and number allocation.”

Microsoft Teams allows phone number assignment via the Teams Admin Center or PowerShell, but managing numbers at scale can be time-consuming. Orto simplifies Teams number management with automated policies, user-based routing, and real-time visibility across tenants.
Microsoft’s native tools are designed for basic number assignment. Orto goes further, offering rule-based provisioning, shared number pools, tenant-wide control, tags, number quarantining, custom locations, audit logs, and full lifecycle tracking – all from a single platform.

With Orto, you can also go a step further and assign numbers automatically based on job role, location, department, or Entra ID groups, removing the need for manual configuration in Teams Admin Center.

You will need to continue to use the Teams Admin Centre to purchase additional numbers from Microsoft or your Operator. However, once purchased, you can manage them all from the Callroute portal including assigning numbers to users and resource accounts.
No. There is no limit to the number of ranges or numbers within these ranges. You can add as many as you need for your business.
If you are using Callroute for your carrier services e.g. BYOC or our calling plans, number management is included in your standard Callroute per user licence. To use Callroute’s number management for other calling services e.g. Microsoft Calling Plan or Operator Connect numbers then there is a bolt-on licence you can purchase from your Callroute partner.
Absolutely. Orto enables shared number pools across multiple users, departments, and tenants, ideal for use cases like hotdesking, sales teams, or customer service groups.
Changes made directly in the Callroute Portal are instantly detected. Changes made outside the portal e.g. via PowerShell or Teams Admin Centre will be discovered during the next scheduled synchronisation. Alternatively, you can manually initiate a synchronisation whenever you feel it is necessary.
Yes. Providing your carrier services are routing via Callroute to your PBX, number management can be used.
Yes, as long as you are using BYOC or Callroute Calling Plans. Our intelligent routing allows you to assign individual numbers to any user on any service that you connect to Callroute. Whether that is Teams, Webex, PBX or Zoom. It is not possible to route Microsoft or Operator Connect numbers to different phone systems as Callroute is not party to the call control of these ranges.
