Staff Training for a New Phone System: 30-Minute Plan

Tom Reed · Updated 31 October 2026

You can train a team on a new hosted PBX phone system in about 30 minutes. Cover five things in order: get the app connected, make and transfer calls, handle voicemail, use presence and chat, and find call history. Finish by handing everyone a one-page cheat sheet.

This guide is for the office manager or owner who has just switched the business to a new phone system and now has to get everyone using it. It assumes the admin side is already done: people have been invited, extensions exist and calls are routing. What's left is the part that decides whether the change sticks, which is getting staff comfortable with the app. If you're an MSP or IT reseller, the last section shows how to reuse this plan for every customer you put on SessionPBX through the SessionPBX partner programme. Throughout, Teams Phone and Teams Business are SessionPBX plans, not Microsoft Teams.

What should staff training on a new phone system cover?

Good phone system training is short, hands-on and done with the app open. Most people don't need to know how the system works behind the scenes. They need to know how to answer, how to pass a call on, where their messages are and how to tell whether a colleague is free. Keep the session practical: everyone brings the phone or laptop they'll actually use, and every block ends with them doing the thing, not watching you do it.

Here's a suggested plan. It isn't a measured benchmark, just a sensible split that keeps each topic short enough to hold attention. Stretch or squeeze the blocks to suit your team.

Run it as one session for the whole team if you can. If people work shifts or remotely, run it twice rather than letting anyone skip it. The people who miss training are the ones who end up forwarding calls to their personal mobile.

How do staff install and connect the app?

Start with the step that causes the most worry and turns out to be the easiest. The admin invites each person by email from the portal. That email is how they connect: on a mobile they scan a QR code, and on a desktop they open a setup link. The app connects to the business phone system with their calling and messaging settings ready to use. There are no SIP settings to type and no config file to pass around.

Point people to the softphone apps for Windows, macOS, iOS and Android before the session so the download is out of the way. The same account works across all four, so someone can use the desktop app at their desk and the mobile app when they're out, with the same history. Push notifications mean incoming calls still reach the phone when the app isn't open, and calls ring the devices a person has registered, so they can answer wherever it suits them.

In the session, ask everyone to connect at least two devices if they have them, then call each other to prove it works. Ask them to check the app shows their name and extension. If you're rolling out the desktop app across a lot of machines at once, our guide to rolling out desktop softphones on Windows and Mac covers the deployment side.

How do you make, hold and transfer calls?

Once everyone is connected, move straight to calls. Staff can make voice and video calls to colleagues and customers from any of their devices. Show them how to dial a colleague by extension or from the team directory, how to answer, and how to put a caller on hold and come back to them.

Transfers are where most people get nervous, so give them the most practice. There are two ways to pass a call on:

• Transfer directly. The call goes straight to the colleague. Use it when you know they're free and the caller just needs the right person.
• Speak to a colleague first. Put the caller on hold, talk to the colleague, explain who's calling, then hand the call over. Use it when the colleague needs context or might not be able to take it.

If people aren't sure when to use which, our post on warm transfer vs blind transfer explains the difference in plain terms.

Practice drill in pairs. One person plays the customer and calls the other. The person answering puts them on hold, then transfers them directly to a third colleague. Next round, they speak to the colleague first before handing over. Swap roles and repeat. Doing it twice each is usually enough to make it feel normal.

How does voicemail work?

Keep this block short and concrete. If the admin has enabled it, staff get voicemail emails with the audio attached, so they can play a message straight from their inbox. The admin can also turn on missed-call notification emails, so people know who needs a call back even when no message was left.

Show them where to listen to, download and manage messages in the portal too, for when they want to go back to an older message or clear out ones they've dealt with. Ask everyone to leave a voicemail for the person next to them and then find it, first in the email and then in the portal. Then agree one simple rule as a team, such as who calls back missed callers on a shared line.

How do presence and team chat help?

Presence is what turns a group of extensions into a team. Before transferring a call, staff can see who's available, which saves the caller from being sent to someone who's away from their desk.

The same app handles team messaging alongside calls: direct messages, group chats and file sharing, with delivery and read receipts and message history kept in sync across devices. Show people how to start a direct message, how to post in a group chat and how to share a file. A good habit to teach is a quick message to check someone is free before a call is passed to them. Our guide to phone system presence and team chat goes into how teams use these together.

Where do staff find contacts and call history?

Finish the hands-on part with follow-up. Colleagues are in the team directory, business contacts are in a shared address book, and incoming, outgoing and missed calls are listed in the call history in the app. Show staff how to find yesterday's missed call and call it back from the history, rather than writing numbers on sticky notes.

If the business is on Teams Business, two extra points are worth covering. Managers have call reports covering call volumes, answered and missed calls, and talk time, with filters by member, direction and outcome. Recording is set for each member by the admin: off, on demand or automatic. Staff should know which applies to them, so tell each person whether their calls are recorded before they start taking them.

Leave the last few moments for questions. Write down anything you can't answer and come back to people with it.

What goes on the one-page cheat sheet?

The cheat sheet is what people will actually use after the session, so keep it to one page and fill it in for your business before the session. Print it, pin it in the team chat and send it to anyone who joins later.

Phone system cheat sheet template

• Connect a new device: open the invite email, scan the QR code on mobile or open the setup link on desktop.
• Put a caller on hold: [fill in where the hold button is in your app].
• Transfer directly: [fill in the steps].
• Speak to a colleague first, then transfer: [fill in the steps].
• Check voicemail: open the voicemail email, or sign in to the portal at [fill in your portal address].
• Check presence: look for a colleague's status before transferring; [fill in what each status means for your team].
• Team chat: [fill in the group chats your team uses and what each is for].
• Your phone admin: [name].
• Who to contact for help: [name and how to reach them].

Leave space at the bottom for each person to note their own extension. The template is deliberately simple. If something on it confuses people, that's a sign the training missed it, so fix the sheet and mention it at the next team meeting.

For MSPs and IT resellers: make this your standard customer training

If you sell phone systems, training is the part customers remember. A consistent session for every new customer gives their staff a confident start with the app and the features they're paying for. This plan is built to be reused: the same agenda, the same drill, and a cheat sheet you fill in with each customer's details. For the steps before training, see our guide to MSP customer onboarding on a hosted PBX.

The SessionPBX partner programme is for PBX resellers, managed service providers, IT companies and communications providers that sell phone systems to business customers. Here's what it gives you, as described on the partner page:

• You own the customer relationship. You set your own price and invoice your customer. There are no commissions to chase and no payouts to wait for.
• Hosted or self-hosted. Put small customers on the hosted platform, where SessionTalk takes care of hosting and maintenance, or self-host SessionPBX on your own infrastructure. Self-hosted is available to approved partners only.
• One project per customer. On hosted, each customer gets their own SessionPBX project under your partner account. You create it, you own it, and you manage extensions, the SIP trunk and call flows for that customer. Self-hosted partners can run many customer tenants on their own server, with every customer kept separate.
• App logo branding. Put your logo and in-app product name on the softphones your customers use, so staff see your brand in the app and in their setup emails from the first invitation. App logo branding is included with Teams Business and available as an add-on on Teams Phone.
• Bring your own trunk. Customers connect the SIP trunk they already use, from any SIP-compliant carrier.

You don't need a portal account to apply, and every application is reviewed by our team, by hand.

FAQ

How long does phone system training take?

About 30 minutes using this plan: a short block each for app setup, calls and hold, transfers, voicemail, presence and chat, and call history with questions. It's a suggested plan, so adjust it to your team.

Do staff need to enter SIP settings?

No. The admin invites each person by email, and they connect by scanning a QR code on mobile or opening a setup link on desktop. Their calling and messaging settings are ready to use.

Can staff use the same account on mobile and desktop?

Yes. The same account works on Windows, macOS, iOS and Android, and message history stays in sync across devices.

What's the difference between a direct transfer and speaking to a colleague first?

A direct transfer sends the caller straight through, while speaking to a colleague first lets you explain the call before handing it over. The transfers section above has a practice drill for both.

Can voicemail come by email?

Yes. When it's enabled, voicemail emails arrive with the audio attached, and missed-call notification emails can be turned on as well.

Are Teams Phone and Teams Business Microsoft Teams?

No. Teams Phone and Teams Business are SessionPBX plan names. SessionPBX is a standalone phone system and isn't related to Microsoft Teams. For background on phone systems in general, see what a PBX phone system is.
