Tango Fix4Bizz
Tango Fix4Bizz: Simple Business Telephony, With Strings Attached
⚠️ Key limitation upfront: Tango Fix4Bizz only works on a Tango internet connection. If you use a different internet provider, Fix4Bizz is not available to you. This ISP lock-in is the most important factor to consider before choosing this product.
📞 Tango Fix4Bizz is a hosted Cloud PBX service offered by Tango SA, Luxembourg's second-largest telecom operator. It targets freelancers and small businesses that want a simple, fully managed phone system bundled with their existing Tango internet and mobile services.
This page covers what Fix4Bizz includes, what it costs, who it suits, and where it falls short.
At a Glance
✅ Choose Tango Fix4Bizz if: You have 1 to 15 employees, already use Tango for internet and mobile, want a simple all-in-one solution with hardware included, and do not need advanced features.
🟡 Consider alternatives if: You need a desktop softphone, call recording, analytics, or CRM integrations. Fix4Bizz does not include these. Businesses expecting to grow beyond 20 employees will likely need to migrate platforms later.
❌ Tango Fix4Bizz is not suitable if: You use a non-Tango internet provider, have cross-border operations needing BE/DE/FR numbers, or require flexible contract terms. The mandatory 24-month contract and ISP lock-in are hard constraints.
Detailed Comparison
Tango Fix4Bizz and Voxbi are both Cloud PBX services available in Luxembourg. They serve different business profiles. The sections below cover the key differences.
💶 Pricing and Contract
Tango Fix4Bizz starts from 9.90 EUR per user per month (excl. VAT). This is the only price published on the website. Full pricing for different phone models and additional services requires contacting Tango sales.
The contract minimum is 24 months. Early termination fees apply.
The published price does not include the cost of a Tango internet subscription, which is required for Fix4Bizz to function. If Bizz2Go (the mobile app) is needed, a Tango mobile plan is also required. The real total cost is therefore higher than the starting figure suggests.
Voxbi publishes its pricing openly. There is no mandatory ISP requirement, and contract terms are flexible.
🌐 ISP Independence
Fix4Bizz is tied to Tango's internet network. The phone system will not function on any other internet connection. If your office uses a different ISP, or if Tango's internet service is interrupted, all calls stop.
Voxbi works on any internet connection. Businesses can use their preferred ISP, add a backup connection from a second provider, or use mobile data as a fallback.
For businesses that already depend on Tango for internet, this constraint may be acceptable. For any business with ISP flexibility or continuity requirements, it is a significant risk.
📱 Softphone and Device Options
Tango Fix4Bizz includes rental of Yealink desk phones (T42U, T46U, T48U, DECT, and conference models). Hardware is covered in the monthly fee.
The Tango Bizz2Go app (iOS/Android) extends the system to employees' smartphones. Bizz2Go works via the Tango mobile network, not over WiFi or data. A Tango mobile subscription is required. The app is not usable on a non-Tango SIM.
There is no desktop softphone for PC or Mac. Employees who work primarily from a laptop cannot make or receive business calls without a desk phone.
Voxbi provides a desktop softphone for PC and Mac, a WiFi-based mobile app, and support for desk phones. All three work on any internet connection without a specific SIM requirement.
⚙️ Features and Integrations
Fix4Bizz includes a core set of telephony features: auto-attendant (voice reception), voicemail, call forwarding, call pickup groups, call cascade (sequential ringing), and absence management. All features are included in every plan. There are no tiered packages.
The system does not include: call recording, call queues (ACD), desktop softphone, video conferencing, team messaging, screen sharing, CRM integrations, Microsoft Teams integration, call analytics, or API access.
Voxbi includes all of the above features, or they are available as add-ons. For businesses that need to track missed calls, measure response times, or connect their phone system to a CRM, Fix4Bizz does not meet those requirements.
🗺️ Geographic Coverage
Tango Fix4Bizz provides Luxembourg phone numbers. The service supports multi-site setups within Luxembourg.
International virtual numbers (Belgium, Germany, France) are not available. Businesses serving cross-border clients in the Greater Region cannot present a local number in those countries.
Voxbi provides virtual numbers in Luxembourg, Belgium, Germany, France, and other countries. For businesses active across the Greater Region, this is a material difference.
📊 Reporting and Administration
Fix4Bizz includes a basic self-service portal for configuration. There are no real-time dashboards, call analytics, or reporting tools.
Business owners and managers cannot see how many calls are missed, what the busiest hours are, or how long customers wait before being answered.
Voxbi provides live dashboards, advanced call analytics, and detailed reporting. For any business where call performance matters, the absence of analytics in Fix4Bizz is a notable gap.
Frequently Asked Questions
Can I keep my existing phone number if I switch from Tango?
Yes. Luxembourg number portability is regulated by the ILR (Institut Luxembourgeois de Régulation). You can transfer your Tango number to another provider. The process takes a few business days and must be initiated by the new provider.
Can I use Tango Fix4Bizz if I have a different internet provider?
No. Fix4Bizz requires a Tango internet connection. It will not function on another ISP's network. If you switch internet providers, you would need to switch your phone system as well.
Does Tango Fix4Bizz work for businesses with employees in Belgium, Germany, or France?
Partially. The Bizz2Go mobile app allows employees to use their business number while abroad. However, Fix4Bizz does not provide virtual numbers for Belgium, Germany, or France. If cross-border clients need to call a local number in their country, Fix4Bizz does not cover this.
What happens to my Yealink phones if I leave Tango?
Yealink phones are based on the SIP protocol, which is an industry standard. In many cases, Yealink phones can be reconfigured to work with a different Cloud PBX provider. A migration specialist can assess your specific models and confirm compatibility.
Is Tango a regulated operator in Luxembourg?
Yes. Tango SA is regulated by the ILR (Institut Luxembourgeois de Régulation) and must comply with Luxembourg telecom regulations, including number portability and emergency services rules.
