A practical guide to multi-site connectivity planning

Start with each site, not the network

Before thinking about how locations connect, describe each one. A head office, a branch, a warehouse and a retail store usually have quite different needs. For every site, note:

How many people work there, and during which hours.
What the site does and which systems it relies on, such as point-of-sale, stock control or cloud apps.
How calls are made and answered at that location.
How disruptive an interruption would be for that site specifically.

Review every address separately

The options at one location say nothing reliable about another. Services can differ between towns, streets and even buildings, so each address needs its own review. It is quite normal for a multi-site business to end up with different connection types at different locations, chosen to suit what each address and site requires.

Building access, equipment space and cabling can also vary from site to site, so record a contact person for each location early.

Agree shared standards

Shared standards are the common rules and settings you want every site to follow, even where the underlying connections differ. They make support simpler and help staff move between locations. Consider standards for:

Network security and firewall policy (a firewall controls which traffic may enter or leave a network).
Staff and guest Wi-Fi naming and separation.
Voice numbering, extensions and how calls move between sites.
Device setup, naming and documentation.

Standards should be adapted where a particular site’s options or needs call for it, rather than forcing an identical design everywhere.

Consider how sites reach shared systems

Think about where your important systems live and how each site gets to them. If most work happens in cloud apps, each site mainly needs reliable internet access with sensible security. If some systems are hosted at a head office, sites may need a secure connection to that location. These choices are reviewed against your requirements rather than decided up front.

Sequence the rollout

Changing several sites at once increases risk. A sequenced rollout lets you learn from the first location and apply those lessons to the rest. Consider:

Starting with a site that is representative but not the most critical.
Working around each site’s busy periods.
Dependencies, for example a head office that other sites rely on.
How existing contracts and end dates differ by location.

Plan the handover for each location

Each site should finish with clear documentation, a named local contact, guidance for staff and a simple route for reporting problems. A consistent handover pack across sites makes ongoing support far easier, even when the sites themselves are different.

Keep a simple site register

A site register is a single shared document that lists every location and its key details. It becomes the reference point for planning, reviews and day-to-day support. For each site, record:

The full address and a local contact person.
Current services, providers and contract end dates.
Where network equipment is kept and who has access.
Any agreed exceptions to your shared standards, and why.

Keeping the register up to date as sites open, move or close helps prevent forgotten services and makes future changes easier to plan.

Questions to bring to your review

What does each of our sites need, based on its people and systems?
What must be confirmed separately for each address?
Which standards should apply across all sites, and where should they flex?
How should each site reach our shared or cloud-based systems?
Which site should go first, and in what order should the rest follow?
What should the handover look like at each location?

Final service options, availability and delivery steps are confirmed during the relevant address and requirements reviews.
