Hosted telephony / managed service
Hosted PBX and telephony with support wrapped around the system.
Choose a managed business telephony service when you want the provider to look after the platform, moves and changes while your team focuses on using it.

What this can include
Judge hosted telephony by what happens after installation.
For SMEs without a dedicated voice engineer, day-two support matters as much as day-one features. The service should make user changes, call-flow updates, fault ownership and growth predictable.
Routine changes without PBX expertise
Add starters, leavers, groups and opening-hour changes without running specialist infrastructure.
Plan failure handling in advance
Decide how inbound calls behave if a site or connection is unavailable.
Design for growth and office changes
Use a managed model that can accommodate new users or sites without a complete phone-system replacement.
Designed around the workplace
A managed service works best when support ownership is clear.
Hosted telephony can reduce the day-to-day technical burden, but the user experience still depends on sensible call flow, endpoint choice, number migration and a support process that people can actually use.

Is it right for you?
Where this option works best.
Hosted telephony works well for SMEs that want a managed phone service without maintaining PBX infrastructure themselves.
Choose this when
Your SME wants one supplier to design, migrate and support the business phone environment and you do not want to maintain PBX infrastructure internally.
Consider another route when
If your priority is specifically a cloud-hosted PBX architecture, see Cloud PBX. If you want a Yeastar P-Series platform with deployment choice, compare the Yeastar page.

Common questions
Frequently asked questions.
Short answers to the questions we are most often asked about this type of system.
What is hosted telephony?
It is a managed business phone service where the core telephony platform is hosted rather than maintained as traditional PBX hardware at your office.
Who manages changes to the system?
That depends on the service design. We agree which changes your administrators can make and which changes Zero will manage for you.
Can we use desk phones and softphones together?
Yes. A mixed endpoint design often makes sense: fixed roles can use Yealink handsets while hybrid or mobile users use supported softphone clients.
Can existing numbers be moved?
In many cases yes. Number ranges are checked for portability and the port is planned as part of migration.
