23 Powerful Benefits of VoIP for Homes & Businesses
VoIP is becoming the preferred choice for homes and businesses across the UK. Below, we explain the key benefits of VoIP and why digital voice is a smarter, more flexible alternative to the traditional landline.
The 23 Powerful Benefits of VoIP
Discover the main benefits of VoIP for homes and businesses, and see how MIH VoIP can help you future-proof your phone service ahead of the UK landline switch-off.
Keep Your Existing Landline Number
One of the key benefits of VoIP is that you can keep your existing landline number when switching to digital voice – ideal preparation for the 2027 Big Switch Off.
Use Your Familiar Landline Handset
Use your existing phone with a VoIP Adapter — no need to replace equipment.
Make & Receive Calls on Any Device
Use the VoIP App on your smartphone, tablet, laptop, PC, iMac or MacBook.
Enjoy Lower Call Costs
VoIP typically reduces call charges compared to traditional landlines.
Work From Anywhere
Another important benefit of VoIP is that your phone number is no longer tied to a wall socket. You can work from home, a friend’s house or even abroad as long as you have an internet connection.

Explore the Benefits of VoIP that offer significant advantages for both residential and business users.
In hours Voicemail greeting…
Sorry, no one is available to take your call right now, please leave a message and we will get back to you.
Out of hours Voicemail greeting…
Our offices are now closed. Our opening hours are Monday to Friday, 8.30 am to 5 pm. Please leave a message and we will get back to you during office hours.
Our systems will email you with the audio file and transcription of the Voicemail message left. We can set the voicemails to automatically delete after they have been emailed, or leave them there for you to access via the VoIP App or VoIP Phone.
Call Timers
These are your Business opening hours, so if you are open for business, your VoIP Phone(s) will ring, and if you are closed, then any incoming calls will go directly to your Voicemail for you to pick up at your convenience.
Let us know your Business opening hours, and we can set these up for you. We will need an out-of-hours call greeting to play, see below.
Call Greetings
These can give a more professional or friendly edge to your business, depending on your wording and how you want them to sound. These can be 2 versions, or just 1 version if you don’t want any “Call Timers” set up.
In Hours Call Greeting…
Thank you for calling MIH VoIP, please note all calls are recorded for training and monitoring purposes.
If the business is closed, then use the Out of Hours Voicemail message…
Our offices are now closed. Our opening hours are Monday to Friday 8.30 am to 5 pm. Please leave a message and we will get back to you during office hours.
Auto-attendants
You may have different business locations, 1 number for the same Restaurant chain, but multiple venues to eat.
You may have different departments such as Sales, Support or Accounts, etc.
We can set up an Auto attendant where the caller can hear your Call Greeting, then they can hear something like…
Thank you for calling MIH VoIP, please press 1 for Sales, 2 for Support or 3 for Accounts.
Your messages, your way
The Auto Attendant, Voicemail and Call Greetings can say anything you like. Send us a script, and we can create it using our text-to-speech tool—but we recommend a real human voice.
If you have an audio file, you can send it via WhatsApp.
If not, record one with your phone’s sound recorder or WhatsApp voice note. Many customers send multiple versions while practising; we’ll either use the last one or the one you choose. Send as many as you like—we want you to be happy with your message.
Our business WhatsApp Number is on our contact page.
Call Recordings
We can enable call recording for your account, accessible via any web browser. This is useful if you need to revisit a conversation. Please ensure to let us know if you want us to enable this feature.
Note: Call recordings can’t be used for legal matters unless the other party is informed. Incoming calls are covered if you have a “Call Greeting” set. For outgoing calls, get into the habit of saying, “All calls are recorded for training and monitoring purposes.”
Your package includes 30 days’ free storage, with upgrade options available.
Extras and upgrades
Desk Phones & Cordless Phones.
We can supply Desk Phones or Cordless phones programmed with your VOIP Account with us, or reconfigure any existing VoIP Phones you may have.
You can have multiple devices for your VoIP Account with us, so you can use what is best for you.
Multiple User licenses
Maybe you have hired more staff, or taken on a Virtual assistant or someone to handle your calls for you. Maybe you need to transfer calls to different people in your business. We can scale and grow with you by adding Users as and when you need to.
