Microsoft Teams Phone Migration in Portsmouth
Moving Portsmouth organisations onto Teams Phone in stages, which means running two systems at once and deciding where every call lands while you do. Coexistence is configurable per user, and a migration where nobody has settled which client rings produces missed calls that are difficult to explain and harder to reproduce.
Why this comes up
The problem
Half the company has moved, calls to the other half ring in two places or nowhere, and nobody can say why.
What you get
What we deliver
- Coexistence mode set deliberately per user rather than left at the tenant default
- A pilot group chosen from people who will report problems rather than tolerate them
- Internal calling between migrated and unmigrated users tested before the first wave
- Transfers between the two systems verified, since these fail in ways calls do not
- Voicemail routed to one place, because two mailboxes is the common complaint
- Waves organised by team so the people who cover each other move together

Microsoft Teams Phone Migration in Portsmouth — common questions
- What does coexistence actually control?
- Where a user's calls arrive and which client they place them from. Set inconsistently across a part-migrated organisation, it produces users whose calls ring in the old system while they wait in Teams — and the symptom presents as an unreliable phone system rather than a configuration choice.
- Why move teams together rather than by floor?
- Because cover arrangements follow teams. People who pick up each other's calls, share a queue or transfer routinely need to be on the same platform, and splitting them across two systems breaks the informal arrangements that keep the phones answered.
- What usually breaks first?
- Transfers between systems. Calling across the two platforms tends to work while transferring a live call between them does not, and since reception transfers constantly this surfaces within an hour of the first wave unless it was tested beforehand.
- How long should coexistence last?
- As short a period as the porting schedule allows. Every additional week doubles the support burden and the opportunity for confusion, so the sensible plan compresses the overlap deliberately rather than allowing it to extend while teams decide when they are ready.
- Do you work with businesses across Hampshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Portsmouth and the surrounding Hampshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Portsmouth businesses do you usually work with?
- Port, ferry and defence logistics systems, plus visitor operations for the waterfront attractions. Beyond that we work across Marine & Defence, Ports & Ferries, Higher Education, Retail and Tourism.
- Do you cover the areas around Portsmouth?
- Yes — we work throughout South East, including Southampton, Chichester, Brighton. Portsmouth is an urban area of roughly 240,000+, and we take on work across the wider Hampshire region rather than the city boundary alone.
