The best Gamma alternatives for UK business calling are RingCentral RingEX, Zoom Phone, Dialpad Connect, GoTo Connect and 8x8 Work when you want to change the phone platform. Evaluate BT Business or Vodafone Business separately when the requirement is carrier connectivity, retained equipment or Microsoft Teams calling.
This guide compares Gamma Communications, including Horizon, PhoneLine+, SIP and Teams voice. These Gamma competitors address different service boundaries. A Gamma replacement may mean a new phone system, a different carrier or a change in the partner providing support; identify that requirement before comparing prices.
Choose Gamma Alternatives For Horizon, PhoneLine+, SIP Or Teams
Assess Gamma alternatives by product, carrier and the business operating the service. Gamma alternatives should be matched to what your company actually purchases rather than the Gamma portfolio as a whole.
Gamma lists Horizon as a cloud phone system, PhoneLine+ as a small-business line service, and separate Microsoft Teams voice options. Its portfolio also includes CircleLoop, Webex for Gamma and SIP services. Those names describe different products or connectivity arrangements; they are not interchangeable specifications.
- Horizon: assess Gamma alternatives for employee calling, reception, queues, integrations and administration.
- PhoneLine+: compare Gamma alternatives by a proportionate line service, number retention and simple call handling.
- SIP trunks: assess Gamma alternatives for retained equipment, concurrent capacity, numbers and resilience.
- Teams calling: compare Gamma alternatives by licences, tenant ownership and the selected connectivity method.
Give Gamma competitors an inventory of numbers, users, sites, devices, contracts and support tasks. A useful Gamma replacement should reproduce the required workflow and assign responsibility for everything that remains.
If you currently use Horizon Contact, identify agent, queue and supervisor requirements separately. Among Gamma competitors, an employee phone subscription does not automatically replace a contact-centre configuration.
Gamma Alternatives Compared: UK Prices, Ratings And Free Trials
G2 Customer Ratings: RingEX: 4.2/5 from 1,518 reviews; Zoom Phone: 4.6/5 from 2,682; Dialpad Connect: 4.4/5 from 4,216; GoTo Connect: 4.4/5 from 1,422; 8x8 Work: 4.2/5 from 941. These are product listings, not separate UK-plan or reseller-service ratings.
Compare Gamma alternatives against the same UK users, number types, calling destinations and service responsibilities. Verified GBP pricing is shown where established; other regional prices require a current quote rather than an assumed conversion from US dollars.

Pricing, ratings and evaluation information checked October 25, 2026. Confirm VAT treatment, commitment, minimum users, number charges, calling, hardware and add-ons. A demo is not a free trial. A refund policy or an unrelated product’s trial does not establish free phone service.
1. RingCentral RingEX: Unified Communications For UK Teams
RingCentral RingEX belongs among Gamma alternatives when the business wants to evaluate calling, messaging and meetings in one platform. Compare Gamma alternatives by UK configuration and the organisation responsible for implementation and support.
Pricing boundary: obtain a current UK quote for the tier, users, numbers, calling allowance, integrations and devices. A dependable current public GBP tier price was not established in the reviewed UK pricing page. US Core pricing should not be presented as a UK subscription.
Trial: RingCentral’s UK hosted-PBX page advertises a 14-day free trial for RingEX. Confirm account eligibility, included features, numbers and usage limits before starting. Do not assume a small evaluation reproduces a complete multi-site deployment.
Ask Gamma competitors to demonstrate reception, queues, permissions and a routine user change. A RingEX-based Gamma replacement should include number migration, training, ongoing administration and escalation ownership. When comparing Gamma competitors, treat RingCX as a separate contact-centre product.
2. Zoom Phone: Calling In An Existing Zoom Workplace
Zoom Phone is relevant among Gamma alternatives when employees already use Zoom and want business calling in that environment. Before comparing Gamma alternatives, identify whether the current issue concerns the application, carrier connection or operating partner.
Pricing boundary: Zoom documents a UK & Ireland calling option, but a current exact GBP figure was not established here. Request the applicable package, users, numbers, destinations, Workplace dependencies and VAT treatment. US & Canada prices do not establish a UK telephone-service offer.
A demonstration is available. An exact current UK Phone free trial and duration were not verified. A free meetings account or a US calling promotion does not establish UK Phone trial access.
Compare Gamma competitors using real UK reception, transfer and administrator tasks. For this Gamma replacement, use the route for 1–50 users or the route for 50+ users. Our Zoom Phone review provides product context. Contact Center needs a separate scope check.
3. Dialpad Connect: Calling With Transcription And Summaries
Dialpad Connect is one of the Gamma alternatives to evaluate when employee calls, transcripts and AI summaries matter. Test Gamma alternatives using representative UK accents, terminology and call conditions, together with the effort required to correct or use the output.
Pricing boundary: current official GBP plan data lists Standard at £12 per user/month with annual billing or £22 monthly. Confirm the UK account offer, VAT, numbers and usage. Pro adds key CRM integrations, multi-office management and 24/7 support. Support and Sell are separate products.
Trial: the UK pricing page advertises a 14-day Connect free trial. Confirm account, country and number eligibility, plus access to the required integration and administrative functions.
Have Gamma competitors demonstrate shared numbers, reception, transfers and the purchased integration tier. A Dialpad-based Gamma replacement also needs record access, identity and mobile behaviour checked. An app on a smartphone is different from native carrier SIM service.
4. GoTo Connect: Office Calling And Customer Routing
GoTo Connect merits consideration among Gamma alternatives when central phone administration and customer routing are priorities. Test Gamma alternatives with a real business-hours schedule, receptionist task and overflow scenario in the demonstration.
Pricing boundary: ask Gamma competitors for UK-specific proposals. Distinguish Phone System, AI Receptionist packages, CX, CX Complete and Contact Center. Identify integrations, regional channels, AI allowances, number charges, devices and support on the actual quoted package.
Official Connect material provides demos. An exact current UK Connect free trial with verified duration was not established. Trial terms for another GoTo product do not demonstrate Connect trial access.
Ask Gamma competitors to show both the caller experience and the administrator’s maintenance tasks. A GoTo-based Gamma replacement should address devices, number migration and support ownership. Our GoTo Connect review adds product context.
5. 8x8 Work: UK Calling Across Business Locations
8x8 Work completes the platform shortlist of Gamma alternatives for companies comparing calling, meetings and messaging across locations. When assessing Gamma alternatives, confirm local telephone-service availability separately from the overseas destinations staff can call.
Pricing boundary: ask Gamma competitors for a current Work quote covering UK numbers, users, destinations, integrations, support and any additional countries. Contact-centre or Teams-related requirements need their own entitlement checks. Historical X Series prices are not a current UK deployment quote.
Official Work pages provide demos and tours. A generally available UK Work free trial with verified duration was not established. Among Gamma competitors, a scoped partner proof of concept requires its own conditions, and an Express trial should not be presented as Work trial terms.
Compare Gamma competitors through local administration and central oversight tasks. An 8x8-based Gamma replacement should demonstrate the purchased country configuration, onboarding process and incident responsibilities.
Gamma Alternatives: Separate Platform And Support-Partner Problems
Compare Gamma alternatives against the improvements your business needs. Gamma alternatives can change the platform, the underlying carrier, the support relationship or several components together.
Gamma publishes several partner models. If a reseller supplies your service, establish the contracting entity, underlying platform and network before interpreting a new supplier name as a different technical service.
Ask Gamma competitors to identify who provisions users, owns number orders, changes routing, monitors incidents, handles bills and escalates carrier faults. Ask Gamma competitors to assign a named responsibility for each task.
A Gamma replacement based only on a different support relationship may preserve useful configuration and staff familiarity. If the platform is the problem, a reseller change alone may leave the same limitation in place.
Test Gamma alternatives using a support incident involving the app, office connection and carrier. Find out who gathers evidence, coordinates suppliers and remains accountable until the business service is restored.
Gamma Alternatives For UK Carrier Connectivity And Retained Teams
Evaluate carrier and managed-service proposals separately from the phone-platform shortlist. Gamma alternatives for retained equipment or Teams connectivity need an architecture specification rather than a feature comparison alone.
BT Business: Carrier-Focused Gamma Alternatives
BT Business publishes inbound voice and SIP services. Consider these Gamma competitors when the business wants to retain compatible equipment or compare the carrier arrangement. Ask Gamma competitors for site eligibility, number transfers, concurrent capacity, resilience, equipment requirements and support responsibilities.
Give these Gamma competitors the same number inventory and traffic profile. Use BT Business inbound voice and SIP to identify the appropriate service, then obtain current GBP pricing and evaluation conditions.
Vodafone Business: Teams-Focused Gamma Alternatives
Vodafone UK publishes Operator Connect and Direct Routing options for Microsoft Teams. Compare Gamma competitors when Teams remains the preferred application and the requirement concerns external calling or its operating provider.
For this Gamma replacement, specify Microsoft licences, tenant control, numbers, connectivity, support and any retained equipment. Visit Vodafone Business Operator Connect and Direct Routing.
Exact prices and generally available trial durations for these bespoke carrier configurations were not established. Request written quotes and pilot terms. No unverified rating is assigned to these proposals, and RingEX’s product score should not be relabelled as a Vodafone service score.
Gamma Alternatives To PhoneLine+: Keep The Specification Proportionate
For a small business needing one familiar number, Gamma alternatives should be assessed against the actual line workflow. A full collaboration suite can introduce features, subscriptions and administration that the business does not need.
Ask Gamma competitors to demonstrate inbound calls, business caller ID, voicemail, opening hours, forwarding and the devices employees will use. Confirm which users or shared endpoints need paid licences.
A proportionate Gamma replacement should also include the internet connection, power and backup assumptions. Give Gamma competitors an inventory of fax, alarm, door-entry or other specialist equipment and validate compatibility with the relevant supplier.
Prioritise the number customers already know and the support process when something goes wrong. A feature-rich product tour does not establish whether the simple daily workflow is easier to operate.
Gamma Alternatives Pricing: Match Complete GBP Quotes And Responsibilities
Price Gamma alternatives using the same users, numbers, sites, devices and calling destinations. Separate platform subscriptions from carrier connectivity, broadband, support, installation and migration work.
Ask Gamma competitors to model ordinary and peak months over the same commitment period. Compare Gamma competitors by minimum users, renewal conditions, annual price changes, out-of-bundle calling, hardware obligations and VAT treatment.
Illustration: 20 Dialpad Standard users at the £12 annual-billing monthly equivalent produce £240/month, or £2,880 over 12 months, in subscription charges. This is not a complete UK quote: the applicable offer, required tier, numbers, usage, devices, managed services and VAT still need confirmation.
- Platform: compare Gamma alternatives by users, shared endpoints, integrations, AI and analytics.
- Telecom: numbers, trunks, destinations, calling allowance and usage.
- Operations: deployment, configuration, monitoring, training and support.
- Access: assess Gamma alternatives for broadband, backup, equipment and installation.
- Transition: record exports, overlapping services and remaining obligations.
A Gamma replacement can reduce subscription charges while moving work to internal staff. Compare the total cost of preserving the required service rather than only the smallest headline figure.
Gamma Alternatives Migration: Separate Numbers, Call Flows And Contracts
Before choosing Gamma alternatives, inventory numbers, services, contracts, users, devices, routing and integrations. Before evaluating Gamma competitors, identify the provider, reseller and administrator with authority over each component.
Have Gamma competitors confirm receiving-service eligibility before scheduling a transfer. Moving a number does not automatically rebuild queues, transfer recordings, preserve every device configuration or end all existing agreements.
- Map ownership: identify numbers, platforms, tenants, devices and service contracts.
- Validate transfers: confirm number types, blocks and receiving-provider requirements.
- Rebuild behaviour: demonstrate reception, schedules, overflow, queues and voicemail.
- Test dependencies: verify identity, CRM, recording access and specialist equipment.
- Preserve records: agree exports, formats, permissions and future retrieval.
- Control cutover: document overlap, rollback, acceptance and support coverage.
Pilot the Gamma replacement with representative users and administrators. Include an urgent routing change, a remote employee and a failed integration alongside successful ordinary calls.
Ask Gamma competitors about residual services and contractual obligations before cancelling anything. Use account-specific dates and written transfer instructions when setting the migration schedule.
Gamma Alternatives Or A Smaller Change: When Keeping Gamma Makes Sense
Keep Gamma when the current platform, number coverage and operating relationship meet the requirement and Gamma alternatives cannot demonstrate enough improvement to justify migration effort.
Compare an updated incumbent proposal with offers from Gamma competitors. A different configuration, support arrangement, integration tier or commercial structure may solve the immediate problem while preserving a working phone system.
A narrower Gamma replacement can be appropriate when the issue concerns only carrier connectivity or the service relationship. Confirm the retained technology and its interfaces so the smaller change does not create a responsibility gap.
How We Evaluated These Gamma Alternatives
We reviewed Gamma’s current product and partner information, official platform and carrier descriptions, regional pricing evidence, evaluation terms and exact G2 product listings. This comparison focuses on UK business calling and collaboration.
This is a documented buying guide, not a hands-on UK call-quality benchmark. Validate Gamma competitors against your sites, numbers, account and workflows. Missing local prices and unverified trial terms are identified rather than estimated.

Frequently Asked Questions
What Are The Best Gamma Alternatives For UK Businesses?
RingEX, Zoom Phone, Dialpad Connect, GoTo Connect and 8x8 Work are relevant platforms for business calling. BT Business and Vodafone Business are worth a separate carrier or retained-Teams evaluation. Match the proposal to the Gamma service and operating responsibilities being changed.
Can I Replace Horizon Without Changing My Support Partner?
That depends on what the partner supplies. Ask whether it can deliver the proposed platform, who owns the underlying service and how migration works. Compare Gamma competitors against the complete technical and support arrangement rather than the supplier name alone.
Which Products Have A Verified UK Free Trial?
RingCentral’s UK hosted-PBX page advertises a 14-day RingEX trial. Dialpad’s UK pricing page advertises a 14-day Connect trial. Exact current UK Phone trials for the other main Gamma alternatives were not established; request the relevant demo or written pilot terms.
How Much Can A UK Calling Subscription Cost?
Dialpad Standard’s current official GBP plan data lists £12 per user/month annually or £22 monthly. Confirm offer details, VAT and extras. Other Gamma alternatives require current UK quotes here; their complete costs depend on the chosen plan and operating scope.
Can I Keep Microsoft Teams And Change The Voice Provider?
Potentially. Have Gamma competitors confirm licences, tenant control, number eligibility and the relevant Operator Connect or Direct Routing arrangement. A carrier change does not always require a new employee application, but it still needs a validated migration plan.
Can I Keep My Business Numbers?
Possibly, depending on ownership, number type, block structure and receiving-service eligibility. The proposed Gamma replacement should confirm the full inventory before cutover. Number porting does not automatically transfer call flows, integrations, recordings or every existing agreement.
Customer Feedback On Gamma Alternatives: Calling And Advanced Administration
The customer experience with Gamma alternatives varies by product scope and how administrative tasks are handled. The G2 listings used here describe product satisfaction rather than the complete UK deployment or reseller service.
RingEX carries a 4.2/5 rating from 1,518 reviews, Zoom Phone 4.6/5 from 2,682, Dialpad Connect 4.4/5 from 4,216, GoTo Connect 4.4/5 from 1,422 and 8x8 Work 4.2/5 from 941. Interpret reviews against the specific UK plan, integrations and support model.
Test Gamma alternatives against your workflows. For example, a platform can receive positive product feedback while still leaving account ownership, integrations or complex number handling unclear. During the pilot, complete realistic administration tasks, including a user change, a routing change and an urgent support request.
