How does Gamma with Cisco Webex compare to 8×8?

If you’re reviewing your current communications system, these are two platforms you’re likely to come across. Both bring calling, meetings and messaging together, and both can extend into contact centre capability when needed.

For many businesses, this is not about moving to VoIP for the first time. It is about reviewing whether their current setup still fits the way the business works today. That might mean improving reliability, reducing complexity, supporting hybrid teams more effectively, or replacing a platform that no longer gives you the flexibility, reporting or user experience you need.

And with the UK PSTN switch-off deadline set for 31 January 2027, many businesses are also using this point to review older lines, legacy services and wider communications infrastructure as part of a broader refresh.

Why many businesses are reviewing their systems

Many businesses are taking a fresh look at their communications platforms because reliability has dipped, legacy systems have become harder to maintain, or teams have ended up juggling too many separate apps since hybrid working became the norm.

In many cases, the business is already using VoIP in some form, but the setup no longer feels joined up, flexible or easy to manage. A well-planned review gives you the chance to simplify your setup, strengthen performance and create a better day-to-day experience for both employees and customers.

What the platforms actually are

Gamma + Cisco Webex

Gamma offers two Webex-based solutions: Horizon with Webex and Webex for Gamma. Horizon with Webex is designed for SMEs, while Webex for Gamma offers the full Webex experience for larger SMEs and enterprises, all running on Gamma’s UK network.

1. Horizon with Webex – Gamma’s Horizon cloud phone system enhanced with the Cisco Webex app for meetings and messaging.
2. Webex for Gamma – a fuller Webex app experience with calling, meetings and messaging, plus AI features and centralised admin.

8×8 (Work / X Series)

8×8 provides a unified communications and contact centre platform combining voice, video, messaging and customer engagement. The core user experience is delivered through 8×8 Work, with additional capability unlocked through the X Series tiers.

1. 8×8 Work – one app for calling, video meetings and team messaging, including AI-supported tools.
2. 8×8 Contact Centre – an omnichannel platform offering voice, chat, email, social and SMS with analytics and routing tools.

What really matters when you switch platforms

1. Day-to-day experience

   If a platform is not intuitive, people tend to revert to old habits. The ideal is one app that handles everything cleanly, works well on mobile, and lets you switch devices without fuss. Webex is particularly strong for meetings and collaboration, with AI features built in. 8×8 performs well for everyday calling and adds more call-handling capability as you move up the licence tiers.

2. Customer conversations

   If you rely heavily on voice for sales, service, support or reception, your requirements may be more demanding. Webex Contact Centre brings AI-supported tools and strong reporting, while 8×8’s Contact Centre has a strong track record in the omnichannel space and is well known for its routing and analytics capabilities.

3. Admin and control

   IT teams usually care just as much about user management, reporting, security and device coverage as they do about the user experience. Webex Control Hub gives you a single place to manage users, devices, policies and analytics. 8×8 also offers a unified admin experience across unified communications and contact centre, with capability increasing by tier.

A simple comparison

Making the switch work in practice

• Migration and switching

  Switching can be phased and controlled. Number porting can be scheduled with minimal downtime. Webex for Gamma can run alongside your existing system during rollout, and 8×8 Work supports staged onboarding. dbfb manages the migration plan end to end.

• Integrations

  Webex integrates with Microsoft Teams, Salesforce, Zendesk and more. 8×8 also integrates broadly with CRMs and helpdesks and supports Microsoft Teams with certified contact centre capability.

• Reliability and network performance

  Gamma’s UK carrier network is known for strong uptime and call quality. 8×8 offers Global Reach technology to support consistent international performance.

• Security and compliance

  Both platforms offer enterprise-grade encryption, secure cloud infrastructure and compliance features suitable for regulated industries.

• Device support and compatibility

  Both Gamma Webex and 8×8 support softphones, mobile apps, headsets and a wide range of IP desk phones. dbfb checks compatibility before deployment to help avoid unnecessary hardware costs.

Which platform suits which business?

• Choose Gamma + Webex if you want Gamma as your service provider but like the Cisco Webex collaboration experience and admin model.
• Choose Webex Contact Centre if customer experience, AI-supported workflows and contact routing are an important part of the requirement.
• Choose 8×8 Work if you want a straightforward all-in-one communications app with flexible package structures.
• Choose 8×8 Contact Centre if you need omnichannel customer engagement with routing, reporting and AI-enabled functionality.

Final thoughts

Both Gamma with Webex and 8×8 can give businesses a modern cloud communications platform. Both can support calling, meetings and messaging. Both can also extend further when customer engagement becomes more complex.

The better fit usually comes down to this. If you want a more straightforward cloud phone system with Webex collaboration built in, Horizon with Webex is the natural Gamma comparison. If you want a broader Webex-led experience with more advanced collaboration and administration, Webex for Gamma is the stronger fit. If you want a single communications platform with a clear route into higher-tier customer engagement capability, 8×8 is a strong option to consider.

The important part is not just which platform has the longer feature list. It is which one fits the way your business works now, how your teams communicate day to day, and what you need the platform to support over the next few years.
