Deployment blueprint

One phone system for a team that spans five time zones and no office.

Sixty people from Halifax to Victoria, most working from home, a customer base that expects a local number and service in both languages, and a company that lives in Microsoft Teams. This blueprint shows how 3CTel designs routing, numbers and onboarding for a distributed national team.

  • Follow-the-sun routing across time zones
  • Local numbers for each region
  • Calling inside Microsoft Teams

For a team spread across Canadian provinces, 3CTel configures a local number for each region that routes to the people serving it, follow-the-sun rules so the main line is answered by whichever region is open, presence so colleagues can see who is available, and calling inside Microsoft Teams via the integration scoped during planning. Each remote worker has a registered 9-1-1 address, and a new hire is set up remotely without shipping hardware.

Deployment blueprint: a representative, anonymized scenario compiled from how 3CTel implements this kind of organization. No client is named and no result figures are stated; every parameter is a configuration choice we design with you.

Situation

A company with no head office has staff in every region of the country. Clients in Vancouver expect a 604 number and a person awake at nine their time; clients in Quebec expect to be greeted in French. The workday for the company as a whole runs from early morning in the Atlantic to late afternoon on the Pacific coast, which is longer than any one person's shift.

Internal communication already lives in Microsoft Teams. Staff do not want a second app for chat, but they do need a phone number, presence that reflects reality and a way for calls to reach the right colleague without a receptionist.

Requirements

  • A local number in each region that rings the people who serve it, plus a toll-free number for national marketing.
  • Follow-the-sun routing so the main line is always answered by a region that is open, with no manual handover.
  • Presence visible to colleagues, so a transfer is only attempted to someone who is actually available.
  • Calling from inside Microsoft Teams for staff who want one app, and the 3CTel apps for those who do not.
  • Bilingual greetings, with French-first on the Quebec number and a French skill on the client-service group.
  • A registered 9-1-1 address for every remote worker, kept current when people move.
  • A remote onboarding process that gets a new hire calling on day one without hardware shipped.

Call-flow design

Each regional number is a front door to that region's ring group. The toll-free and main numbers use a time-of-day rule that hands answering from east to west as the day progresses and back again the next morning. Direct numbers ring the person, then follow their own rules.

Presence and Teams calling

Calling inside Teams

Staff who live in Teams place and receive 3CTel calls from the Teams client. The integration is delivered via the method scoped during planning and confirmed before activation; users who prefer the 3CTel desktop or mobile app keep those.

Presence that reflects the day

Calendar and call state drive presence, so a colleague in Halifax can see that the Calgary specialist is on a call before trying a transfer.

Meetings on the same platform

Client meetings are held on 3CTel video meetings or Teams as the client prefers; internal meetings stay in Teams.

Business SMS from the regional number

Appointment confirmations and follow-ups go out from the regional number the client already recognizes, and replies land in a shared inbox for that region.

AI agents

The AI receptionist covers the gaps that a distributed team cannot: the hour before the Atlantic team starts, the hour after the Pacific team stops, and any moment when a regional group is fully occupied. It answers in the language of the number that was dialled and switches on request.

  • Takes the caller's name, company, reason and preferred callback time, and sends the transcript to the relevant regional inbox.
  • Books a callback into the regional group's calendar where the calendar connection is scoped during planning.
  • Answers hours, location and 'who handles' questions from an approved list.
  • Transfers immediately to a person when asked, when the caller is upset, or when the topic is outside the approved list. It never discusses pricing or contract terms.

Security, privacy and continuity

  • Every remote user has a registered service address for 9-1-1, confirmed at onboarding and re-confirmed whenever the user reports a move; Canadian VoIP providers must provide 9-1-1 service and warn customers of its limitations, and 3CTel walks each user through that at setup.
  • Recording is enabled on the client-service group only, with an announcement configured with you; direct-number calls are not recorded by default.
  • Per-user credentials with device registration; a departing employee's number is reassigned or parked the same day and their apps are signed out remotely.
  • If a user's home internet fails, calls follow the mobile app on cellular; if a whole region is affected, the follow-the-sun rule routes to the next open region.
  • Outbound international calling is disabled by default and enabled per user on request.

Onboarding a remote hire

  1. Create the user

    The new hire gets a direct number in their region, a place in the regional ring group and, if bilingual, the French skill.

  2. Register the 9-1-1 address

    Their home address is recorded as the registered service address before the apps are activated.

  3. Install the apps

    Desktop and mobile apps, or Teams calling, are set up on a short video call with the 3CTel specialist. A headset is the only hardware.

  4. Test and go

    A colleague calls the direct number and the regional number; the new hire transfers a call using presence. That is the whole onboarding.

What we measure

Calls per regional number and per hour of the national day; calls handed between regions by the follow-the-sun rule; transfers completed versus abandoned; AI receptionist calls taken outside any region's hours; SMS threads per region; users with a confirmed 9-1-1 address; onboarding time from user creation to first call.

What is follow-the-sun call routing for a Canadian team?

It is a time-of-day rule that hands answering from the easternmost open region to the westernmost as the day moves. The main or toll-free number rings the Atlantic group first thing, Eastern and Central through the middle of the day, and Pacific at the end, with each region as backup for its neighbour. Nobody switches anything by hand.

Can a distributed team keep Microsoft Teams and still have a business phone system?

Yes. Calling from inside Teams is delivered through the integration 3CTel scopes during planning, so staff who prefer one app place and receive calls there. Others use the desktop and mobile apps. Regional numbers, ring groups, presence and voicemail work the same way regardless of which client a user chose.

How does 9-1-1 work for employees who work from home in different provinces?

Each user has a registered service address that is confirmed at onboarding and updated whenever they move. Canadian VoIP providers must provide 9-1-1 service and warn customers of its limitations; 3CTel covers this with each user at setup, and the admin can see which users have not confirmed an address.

Frequently asked questions.

Only where clients expect one. Most distributed teams choose a local number for each region they serve actively plus a toll-free number for the rest. Numbers are added later in minutes if a new region opens.

A list of regions, hours and languages, and whether you live in Teams, is enough to design the numbers and routing and quote it.
