Cloud Phone System Architecture

A business phone system is really a set of call rules.

The phone number is only the entry point. Behind it sits the carrier connection, phone platform, call routing, users, devices, voicemail and business-hours logic that determine what happens when somebody calls.

End-to-End Call Path From the public phone network to the person who answers. A well-designed phone system gives the business control over how calls arrive, where they go and what happens when nobody is available.
Call Routing Active
01
Number Business phone number Existing or new numbers provide the public entry point into the phone system.
02
Carrier Calling service The number is connected through a compatible carrier or VoIP provider to the phone platform.
03
Platform Teams Phone or cloud PBX The cloud phone platform controls users, devices, call handling and system features.
04
Routing Attendant & queues Calls can be directed by menu choice, department, location or other routing logic.
05
Users Staff & devices Calls can ring authorised desk phones, computers, mobiles or users working at another location.
06
Unanswered Voicemail & fallback Missed and after-hours calls can follow different rules rather than simply ringing forever.
Call Routing

The useful part is deciding what should happen to each call.

Modern cloud systems can route calls very differently from a traditional single-line phone. Reception can ring several people, callers can choose departments, different sites can share a main number and after-hours calls can follow a completely different path.

Menu Auto attendant “Press 1 for Sales, 2 for Support” or a simpler greeting with direct routing.
Team Call queues Ring available members of a team instead of relying on one reception handset.
Site Multi-location routing One number can potentially route callers to different shops, offices or business locations.
Person Direct users Selected staff can have direct numbers or extensions where the system design calls for them.
Users & Devices

The phone system does not have to stop at the desk.

Depending on the platform and licensing, staff may be able to use physical handsets, desktop applications, laptops or mobile devices while remaining part of the same business calling environment.

Reception Desk phones Dedicated business handsets for reception desks, counters and users who prefer a traditional phone.
Desktop Computer calling Make and receive business calls through supported desktop applications and headsets.
Mobile Business calling away from the desk Suitable platforms can allow authorised staff to participate in the business phone system from mobile devices.
Remote Different locations Cloud platforms can connect users across multiple offices, shops or remote working locations.
Business Hours

The same number can behave differently after hours.

Instead of leaving callers with unanswered ringing, the system can switch automatically to an after-hours greeting, voicemail or another defined destination.

Open Normal call flow Calls follow the daytime menu, queue or reception routing used while the business is operating.
Closed After-hours message Play a different greeting that tells callers the office is closed and provides appropriate instructions.
Message Voicemail or fallback Capture the caller's message or route to another approved destination where the platform supports it.
Planning a New Phone System? Start with the call flow before choosing the handsets.

Who should answer? What departments exist? What happens after hours? Do staff move between locations? Those answers determine the system design much more than the phone sitting on the desk.

Choosing the Phone Platform

Teams Phone or hosted VoIP?

Both can provide professional business calling. The better choice depends on how the business already works, how many users need phones, what devices they prefer and whether Microsoft Teams is already part of daily operations.

Microsoft
Teams Phone

Business calling inside Microsoft Teams.

Teams Phone can suit organisations already using Microsoft 365 and Teams for staff communication. Business calling can become part of the same environment used for meetings, chat and collaboration.

Teams desktop and mobile Users can make and receive supported business calls through the Teams applications they already use.
Auto attendants & queues Build reception menus and team-based call routing without relying on a physical PBX in the office.
Compatible desk phones Physical Teams-compatible handsets can still be used where reception or staff want a dedicated phone.
Multiple locations Users can participate in the same cloud calling environment while working across different sites.
Cloud Telephony
Hosted VoIP

A dedicated cloud business phone system.

Hosted VoIP can be a good fit where the business wants conventional phone-system behaviour without making Microsoft Teams the centre of the solution. It can often provide a familiar handset-first experience with cloud management.

Traditional phone workflow Well suited to reception desks, retail counters and users who primarily want a business telephone.
Auto attendants & queues Cloud PBX platforms can provide menus, extensions, ring groups and team routing.
Wide handset choice Depending on the provider, a range of supported SIP or cloud handsets may be available.
Independent of Microsoft 365 Useful when the business does not use Teams heavily or wants telephony managed as a separate service.
Which One Fits?

Start with how your staff actually answer calls.

Platform selection should follow the workflow. A mobile workforce already living in Teams has different requirements from a retail business with a busy front desk and several roaming handsets.

Teams Phone Microsoft-heavy workplace Worth considering where staff already use Teams and Microsoft 365 throughout the working day.
Teams Phone Mobile & hybrid staff Useful when people work across office, laptop and mobile rather than sitting beside one desk handset.
Hosted VoIP Handset-first business Often attractive where reception, retail or operational staff primarily need straightforward physical phones.
Either Multi-site business Both approaches can support multiple locations when the carrier, network and call flow are designed appropriately.
Before Migration

The phone platform is only one part of the project.

Existing numbers, carrier arrangements, licensing, internet connectivity, emergency calling requirements, handsets and current call flows all need to be considered. A clean migration plans those details before the old system is disconnected.

Numbers Check porting eligibility Confirm which business numbers need to move and obtain the current account information required by the receiving provider.
Licensing Match licences to users Users, resource accounts and phone features may require different licences depending on the selected platform.
Network Check internet & LAN Cloud calling depends on reliable connectivity, sensible Wi-Fi and a network capable of supporting real-time voice traffic.
Cutover Plan the transition Configure users, routing, prompts and devices before the old number or phone service is finally moved where possible.
Handsets & Mobility

Not everybody needs the same type of phone.

Reception, office staff, roaming retail workers and remote users can all have different device requirements. The handset should fit the role rather than forcing every user into the same setup.

Desk Business desk phones Dedicated handsets for reception, offices and users who want traditional physical call controls.
Wireless Cordless & roaming options Suitable systems can support staff who need to move through a shop, warehouse or workplace while remaining reachable.
Software Computer & mobile clients For staff who prefer a headset, laptop or mobile application instead of another physical desk phone.
Teams Phone or VoIP? We can design around the business instead of forcing the business around the platform.

Tell us how calls currently work, how many people answer them, whether staff move between sites and what you want to improve. That is a better place to start than choosing a phone brand first.

Phone System Migration

Replace the old system without losing the call flow.

Moving away from an older PBX or hosted phone platform is not just a hardware replacement. Existing numbers, extensions, reception behaviour, after-hours routing and staff habits need to be understood before the new service goes live.

Migration & Cutover Build the replacement before disconnecting what already works. Where the providers and porting process allow it, the new environment can be configured and tested before the final number cutover.
Planned Migration
01
Audit Understand the current system Record numbers, extensions, users, handsets, queues, menus and current provider details.
02
Design Rebuild the call flow Decide what should ring, where calls should go and what can be simplified in the replacement.
03
Configure Prepare users & devices Create users, queues, attendants, prompts, handsets and supported mobile or desktop clients.
04
Port Move eligible numbers Coordinate number porting with the receiving provider using the required account information.
05
Test Confirm inbound & outbound calls Verify call routing, caller ID, queues, after-hours behaviour and key users after cutover.
Real Business Scenarios

Phone systems should follow the way the business operates.

A professional services office, retail business and multi-location operation can all use cloud telephony very differently. The system should be designed around those differences rather than copied from a generic template.

Reception Busy front desk Ring a primary reception handset while allowing overflow, backup users or a queue to answer when reception is busy.
Retail Staff moving around the site Use appropriate cordless, mobile or roaming solutions where staff are not sitting beside a desk all day.
Professional Services Department routing Route callers to administration, sales, property management, support or other defined teams.
Multiple Sites Shared business number Calls can potentially be distributed between different shops or offices while remaining under one cloud phone environment.
Hybrid Work Office and remote staff Allow supported users to participate in the business call flow when working away from the main office.
Departments Nested call menus More complex organisations can use additional routing levels where a simple single menu is not enough.
Unanswered Shared voicemail Team voicemail can provide a more practical destination than leaving one person's mailbox responsible for a department.
Seasonal Holidays & closures Temporary greetings and alternate call handling can be configured for holidays or special closures where supported.
Multi-Site Calling

Different locations do not need separate isolated phone systems.

Cloud calling can connect users across offices, retail sites and remote locations. Reception at one site can potentially transfer a caller to another location just as easily as transferring to someone in the next room, subject to the capabilities of the chosen platform.

Main Number One public entry point Use a primary business number and route callers to the right location or department.
Transfers Move calls between sites Staff can transfer calls to users or teams in another connected office where the platform supports it.
Overflow Backup reception Another site or user can potentially help answer calls when the normal reception point is unavailable.
Users Central management Cloud platforms make it easier to manage users and call routing across multiple physical locations.
After-Hours Routing

Closed does not have to mean unanswered.

After-hours behaviour can be designed separately from daytime reception. That may include a closure greeting, department voicemail or another approved destination.

Greeting Explain that the office is closed Give callers useful information instead of simply allowing the main number to ring unanswered.
Voicemail Send messages to a team Shared or department voicemail can be more suitable than sending every call to one individual.
Exceptions Alternate routing Where supported and appropriate, certain callers or options can follow a different after-hours path.
↔
Phones Depend on the Network A cloud phone system can only be as reliable as the connectivity underneath it. Internet quality, firewall configuration, switching, wireless coverage and power availability can all affect cloud calling. Where the existing network is weak, we can review that as part of the phone project rather than treating the two systems as unrelated.
Replacing an Existing Phone System? Keep what works, simplify what does not, and plan the cutover before moving the number.

We can review the existing call flow, current provider, number requirements, users, devices and network before designing the replacement.

Routing Reception & queues Auto attendants, call queues, departments, users and after-hours routing.
Locations Multi-site systems Connect staff and call handling across different offices, shops or remote work locations.
Can we keep our existing business phone number?

Often, yes. Existing numbers can frequently be ported to a new provider, but eligibility depends on the number, current carrier and receiving service. The account details should be checked before cancelling the existing phone service.

Should we cancel the old phone service before porting?

Generally, no. Cancelling an existing service before its number has been successfully transferred can create avoidable problems. The porting process and provider instructions should be completed before the old service is closed.

Do we need Microsoft 365 to use Teams Phone?

Teams Phone requires an appropriate Microsoft environment and licensing. The exact licence combination depends on the Microsoft subscription and the calling arrangement being used, so licensing should be reviewed as part of the project rather than assumed.

Can we use Teams Phone if our email is with Google Workspace?

Yes, a business can use Microsoft Teams and Teams Phone while continuing to use Google Workspace for email. The telephony environment still needs the appropriate Microsoft accounts and licences, but email does not have to be migrated to Microsoft 365 simply to use Teams Phone.

Do we have to use desk phones?

No. Depending on the chosen platform, users may be able to answer from a supported desktop application, laptop or mobile device. Physical business handsets are still useful for reception, counters and staff who prefer a traditional phone.

Can staff answer the business number on their mobiles?

Suitable cloud platforms can allow authorised staff to make or receive business calls through a mobile application. The exact behaviour depends on the platform, licensing and call-flow design.

Can one business number ring two different locations?

Yes, cloud systems can be designed so a main number routes to staff, queues or departments across different locations. The exact routing can be based on menus, reception logic, sites or other business requirements.

Can we have an auto attendant such as “Press 1 for Sales”?

Yes. Both Teams Phone and many hosted VoIP platforms support auto attendants or IVR-style menus. These can route callers to departments, users, queues or other destinations supported by the platform.

What happens to calls after hours?

The system can follow a separate after-hours call flow. That might play a closed message, route to voicemail, send a caller to another defined destination or use a different menu, depending on the platform and business requirements.

Can voicemail go to more than one person?

Depending on the platform, voicemail can be designed around a team, group or shared destination rather than one person's private mailbox. This can be particularly useful for reception or department messages.

Will Teams Phone or VoIP work over Starlink?

It can, provided the connection is sufficiently stable for real-time voice. Call quality depends on latency, packet loss, network configuration and overall connection behaviour, not simply the advertised download speed.

What happens if the internet goes down?

Cloud telephony depends on connectivity. Some users may still be able to operate through mobile data or another location, and some platforms or providers can offer alternative routing options. Businesses that depend heavily on phones may also consider backup internet connectivity.

Phone System Design

We start with the business workflow, not a handset catalogue.

The important design questions are who should answer, which teams need queues, whether callers need menu choices, where staff work and what should happen when nobody answers.

Entry Business numbers Decide which existing numbers need to be retained and whether new numbers are required.
Reception Auto attendants Design greetings and menu choices that make sense to callers rather than creating unnecessary menu layers.
Teams Call queues Define who answers each queue and what should happen when all members are busy or unavailable.
Closed After-hours routing Decide what callers should hear and where messages or urgent calls should go when the business is closed.
