What does it mean to use Callroute as your carrier?
Callroute isn’t a telecom carrier — we’re the intelligent layer that connects you to the world’s most trusted networks.
Your phone numbers and calls are delivered via Tier-1 carriers like BT, Gamma and Bandwidth, with Callroute making it simple to leverage these networks through a single platform and one consolidated bill.
Why use Callroute as your carrier?
If you don’t want to bring your own carrier, the decision is not just who provides dial tone — it’s who makes Microsoft Teams calling easier to run, easier to scale, and easier to support.
How using Callroute as your carrier works
Callroute has wholesale interconnects with major Tier-1 carriers around the world — but all of that complexity is completely abstracted from the user experience.
For you, it’s straightforward:
- Purchase new numbers or port existing ones to Callroute
- Once complete, numbers automatically appear in the Callroute portal, ready to assign to users or services
- Route numbers to the platforms and environments you choose
Behind the scenes, Callroute handles everything else. When a call is made, we intelligently and optimally route it across the appropriate Tier-1 network to ensure reliability, quality and performance — without you ever needing to think about carriers, routing or infrastructure.
Use Cases
Using Callroute as your carrier makes sense when you want simple, scalable cloud voice without managing carrier complexity.
Purchase numbers, deliver PSTN services, and route calls to platforms like Microsoft Teams, Webex and AI services — all from a single pane of glass.
Replacing legacy PSTN providers
Move away from fragmented, on-premise or country-specific carriers. Port your existing numbers into Callroute and deliver PSTN services through modern platforms like Microsoft Teams — without managing multiple carrier contracts.
Scaling voice across regions
Quickly add local, national or international numbers as your business grows. Callroute gives you access to global numbering and Tier-1 carrier networks, all managed centrally and billed through a single supplier.
Simplifying multi-platform voice
Deliver PSTN services to multiple platforms — such as Microsoft Teams and Webex — from one control layer. Callroute handles number management and call routing, so you don’t need separate carrier setups for each platform.
One Vendor, One Bill
Callroute removes the need to contract with and manage multiple telecom providers.
While your calls and numbers are delivered over trusted Tier-1 carrier networks, your commercial relationship stays simple.
You work with one supplier, receive one consolidated bill, and manage everything through one platform — without sacrificing network quality, coverage, or control.
What does it cost?
Pricing depends on your requirements, including:
- Number types (local, national, mobile, toll-free)
- Countries and regions
- Call volumes and usage patterns
- Deployment scale
There are no mandatory carrier contracts and no hidden integration fees. We offer inclusive minute bundles and highly competitive calling rates.
Calling costs are visible in real time through the Callroute dashboards, so you can monitor usage and keep full control of spend at all times.
