Business Phone System Comparison: A Supplier Demo Brief

Compare call scenarios, not just feature lists

A useful business phone system comparison starts with the calls your team needs to handle. Before choosing a platform, write down who answers, where calls go when nobody is available, and what the caller should experience. Use the same brief for every supplier so that a familiar product name or a low headline price does not decide the purchase on its own.

This is a planning checklist for Australian businesses, not a technical design or a promise that a particular edition supports every requirement. Confirm the proposed product, edition, carrier and integrations in writing before committing.

Build a short demonstration brief

Choose examples that reflect your working day. These fictional scenarios are a starting point, not claims about any Bestcomm customer:

• A customer calls the main number during opening hours. Which people should ring, and what happens if they are busy?
• A receptionist needs to speak to a colleague before transferring the caller. What happens if that colleague does not answer?
• A staff member is working away from the office. Which device should receive the call, and which business number should the customer see on a return call?
• A caller arrives after hours or on a public holiday. Who can update the message and schedule?
• A voicemail needs a response. Who owns that follow-up, and how will they know it has been handled?
• A manager needs to understand missed calls. Which report answers that question, and how does it define a missed or abandoned call?

For each example, record the expected result, the supplier's demonstrated result and any dependency or extra charge. Mark an unanswered question as unknown rather than assuming the feature exists.

Ask the same questions of each option

If the shortlist includes a hosted phone service, Microsoft Teams Phone, 3CX or an app-based service, ask each supplier to demonstrate the same call scenarios. Avoid deciding by staff numbers alone. The people answering calls, the call flow and the support arrangements matter to the brief.

Ask which exact licence, edition and carrier arrangement the demonstration uses. If a feature relies on an add-on, separate that dependency from the base service. For a CRM connection, ask which records are read or written, which application versions are supported, and what staff see if the connection fails. Do not use real customer information in an initial demonstration when fictional records will do.

Our unified communications service is a starting point for discussing the communications scope. Where customer records are involved, include the CRM automation requirements in the same brief.

Compare the complete written price

Request a quote in AUD that states whether GST is included and separates one-off costs from ongoing charges. Ask the supplier to itemise:

• Licences, billing frequency, minimum term and renewal conditions.
• Numbers, porting and the treatment of local, mobile and international calls.
• Hosting, handsets, headsets, installation and configuration.
• Training, support hours and any after-hours charges.
• Recording, reporting, integrations and other optional components.
• Cancellation, number-transfer and data-export arrangements.

If a trial is offered, ask what it includes, what remains chargeable and what happens when it ends. This guide does not quote a trial offer, an installation price or a go-live timeframe. Those need confirmation for the actual proposal.

Agree readiness, cutover and support ownership

Ask the proposed provider to assess the existing connection, devices and network before agreeing the implementation plan. Request a documented cutover plan, including responsibility for number-porting coordination, acceptance tests, contingency arrangements and communication with staff. The carrier and implementation team should confirm timing; do not treat an illustrative schedule as a booking.

Record who owns each support boundary: carrier, internet service, network, platform and connected applications. Ask how a problem moves between them without leaving staff to repeat the story. Include security, privacy, recording and retention questions for the appropriate specialist to review rather than treating a product comparison as legal or security advice.

Your next step

Prepare a one-page brief with your opening hours, locations, answering roles, current services and the call scenarios that matter most. Keep passwords and other credentials out of it. Take that brief to each shortlisted supplier and compare the demonstrated results, written scope and complete price.
