Schedule Your Consultation
Replacing a business phone system is about more than choosing a platform.
Your organization must also consider PSTN connectivity, global calling, number porting, licensing, integrations, compliance, mobility, contact centre requirements and ongoing support.
CallTower helps organizations compare leading cloud calling platforms and build a communications strategy around their users, locations, existing technology and long-term business goals. Whether you are replacing an ageing PBX, moving from another UCaaS provider or modernizing voice across multiple locations, CallTower can help you evaluate your options and plan the right path forward.
Which Cloud Phone System Is Right for Your Business?
The right platform depends on how your organization operates today and where it is going next.
Microsoft Teams Calling
Microsoft Teams Calling may be a strong fit for organizations already using Microsoft 365 and Teams that want to bring business calling into the Microsoft working environment. CallTower supports Microsoft Teams Calling deployments through Operator Connect and Direct Routing, along with global PSTN connectivity, number porting, migration support, integrations and ongoing managed services.
Cisco Webex Calling
Cisco Webex Calling may be a strong fit for organizations with existing Cisco investments or businesses looking for an enterprise calling and collaboration platform with flexible cloud migration options. CallTower supports Webex Calling with Cloud Connected PSTN, migration planning, number porting, global voice, analytics, integrations and ongoing support.
Zoom Phone
Zoom Phone may be a strong fit for organizations that want to extend the familiar Zoom environment into cloud business calling. CallTower helps businesses evaluate, deploy and manage Zoom Phone alongside PSTN connectivity, migration services and broader cloud communications requirements.
CallTower supports multiple leading communications platforms. That means the conversation begins with your business requirements—not with a predetermined product recommendation.
What Should You Consider When Comparing Cloud Phone Systems?
A cloud phone system should not simply replace dial tone. It should reduce complexity, support your users and give your organization a communications foundation that can evolve.
CallTower helps your organization evaluate:
- Existing Microsoft, Cisco, Zoom and telecom investments
- User, department and location requirements
- Operator Connect, Direct Routing and PSTN options
- Domestic and global calling requirements

- CRM, compliance recording and business application integrations
