Line vs Vonage

Line vs Vonage Business: which suits a UK small business?

Vonage Business Communications is a traditional cloud phone system: unlimited UK calls, desk phones, extensions and Microsoft Teams, bought on a quote with a minimum term. Line is a mobile-first phone system you sign up to online: texts and WhatsApp on your UK number in a shared inbox, an AI receptionist, and no contract. Pick Vonage for desk phones and unlimited calls. Pick Line if customers text you.

Vonage Business pricing UK (2026)

Vonage publishes three UK plans, priced per user a month. Every plan is sold on a quote, with a minimum term set in your order.

Vonage UK plans, per user a month, excluding VAT
PlanMonthly billingYearly contractWhat it adds
Express£10—Unlimited inbound calls. Outbound calls charged per minute, at a rate Vonage does not publish. Desktop app.
Core£15—Unlimited UK landline and mobile calls, CRM integration, Microsoft Teams, Wi-Fi desk phones.
Max£25—Core plus a Mobile Connect eSIM with a business mobile number and unlimited texts from that phone, which do not sync to the account.

What the headline price leaves out

  • A £3.50 a month Regulatory, Compliance and Intellectual Property fee for every user, every number and every conference bridge. It is not on the pricing page.
  • Virtual receptionist, call groups, call queues, call recording and voicemail transcription are listed as add-on or premium services, with no published price.
  • Desk phones are extra, paid by card or on a monthly payment plan.
  • Leaving before the minimum term ends costs the remaining monthly charges.

Is Line cheaper than Vonage?

Line usually costs a small team less, and you see the full price before you buy. With the RCIP fee, Vonage Core costs £18.50 a user a month before add-ons, and its virtual receptionist and call groups can cost more again. Vonage's unlimited calls can work out cheaper for a team that is on the phone for hours a day. Line's Pro and Business plans have no per-user charge. Price your own team below.

Seat prices are each provider's published price for the plan a small team would buy, with UK calls included up to the provider's fair use limit. Line charges a plan fee plus the calls and texts you use. Handsets, extra numbers and add-ons are not included.

Can Vonage Business send texts from a UK number?

Not from the Vonage app. Vonage's own support page says the app texts in the US and Canada only. Line sends and receives texts on a UK 07 number on every plan.

Vonage

On the Max plan, Vonage supplies a Mobile Connect eSIM with a business mobile number. It sends texts from the phone's own messages app, runs on the EE network with no mobile data, and its texts do not sync to the Vonage account, so the rest of the team cannot see them.

Line

Every Line plan includes a UK 07 number that calls and texts. Replies land in a shared inbox, in the same thread as that customer's calls and voicemails, and anyone on the team can pick them up.

Does Vonage Business have a contract?

Yes. Your order sets a minimum term, cancelling needs 30 days' notice, and leaving early costs the rest of the term. Line is monthly with no contract.

Vonage

Vonage's own early termination example uses a 12-month term. It bills by direct debit only, gives you 7 days to dispute a bill, and moving your number away does not end the contract: you must cancel separately and keep paying until you do.

Line

Line has no minimum term and no setup fee. You sign up online, top up credit for calls and texts, and stop when you choose.

What happens to a missed call on Vonage?

It goes to voicemail, or to a virtual receptionist menu if you pay for one. On Line, a missed call can text the caller straight away, and the AI receptionist can answer instead.

Vonage

Vonage sends unanswered calls to voicemail, and the transcript is a paid add-on. Its AI Virtual Assistant is sold through sales, billed in AI tokens with automatic overage charges, at a price it does not publish.

Line

Add a Send Missed-Call SMS step and the caller gets a text from your number within seconds. Switch on the AI receptionist and it answers in a British voice, takes the details and leaves the transcript in the inbox.

Can you phone Vonage Business support?

No. Vonage supports business customers by chat, Monday to Friday 8am to 6pm and Saturday 9am to 5:30pm, and by case outside those hours. Line offers live chat, email, WhatsApp and phone in UK working hours.

Vonage

Vonage says its chat service is designed for micro and small business customers. Most of its 1-star reviews mention reaching a person, and most of its 5-star reviews thank a named chat agent.

Line

Line's team answers by live chat, email, WhatsApp or phone during UK working hours.

Does Line have the call features Vonage has?

Not all of them. Vonage has a virtual receptionist menu, call groups, call queues with monitoring, call recording and transfer, several as paid add-ons. Line covers opening hours, ring groups, forwarding, voicemail and a missed-call text, and does not record or transfer calls.

Vonage

Vonage's virtual receptionist sets menus, business hours and holiday overrides in the admin portal. Call groups hold up to 25 extensions, and call queues take 100 or more. Each is listed as an add-on.

Line

Line routes each call through a workflow: a Time Rule for opening hours, a ring group that rings only people set to Available, then a missed-call text and voicemail. If you need recording, queues or desk phones, Vonage fits better.

How to switch from Vonage to Line

Most small teams finish in an afternoon, then wait for the number to move.

  1. 1

    Open Line and choose a UK number

    Sign up, pick a UK mobile number and make a test call. The new number works straight away, so you can run Line beside Vonage while you set it up. Nothing changes for your customers yet.

  2. 2

    Rebuild your call flow from a template

    Open Workflows and start from a template such as Business Hours Call Routing or Ring Then Voicemail. Set your opening hours in the Time Rule and choose who rings. The table above shows the Line step for each Vonage feature.

  3. 3

    Invite the team and install the app

    Invite each person by email. They install the Line app on iPhone, or use the web app on a laptop. Only people set to Available ring, so nobody gets calls on a day off.

  4. 4

    Connect WhatsApp and switch on the AI receptionist

    Connect WhatsApp to the same number from Channels, so texts, WhatsApp and calls land in one inbox. Then switch on the AI receptionist and give it your opening hours, your services and how you take bookings.

  5. 5

    Move your number from Vonage

    Go to Settings, then Porting. Enter the number, the account holder and the address Vonage holds, upload a recent bill and sign the letter of authority. Our team sends the request and tells you the switch date. UK moves usually take a few weeks. Calls keep reaching Vonage until that date, and Ofcom rules limit any loss of service on the day to one working day.

  6. 6

    Cancel Vonage after the move completes

    Wait until calls to your number ring in Line, then cancel Vonage. Cancelling first can release the number before it moves.

Before you cancel Vonage
Check the minimum term in your Vonage order first. Leaving early costs the remaining monthly charges. Give Vonage 30 days' notice through its support contact form, and keep the account active until your numbers have moved, or they are lost. Moving a number does not cancel Vonage: cancel separately once the move completes. Only the account's Super User can cancel.
Export these first
  • Company and on-demand call recordings, using the bulk export
  • AI transcripts and call metadata, if you pay for them
  • Contacts as CSV
  • Voicemails you need to keep. Vonage deletes them when the service ends
  • Your virtual receptionist menus and call group settings, as screenshots to rebuild from
