NexGenVoice is a leading cloud PBX solutions provider offering hosted business phone systems powered by Asterisk and FusionPBX. Manage calls, IVR, extensions, and remote teams with a scalable VoIP PBX system designed for modern business communication.
Enterprise-grade phone systems for modern businesses
Our cloud PBX solutions deliver enterprise-grade business phone systems with VoIP PBX technology, advanced call routing, IVR systems, and scalable hosted PBX infrastructure for businesses of all sizes.
Our hosted PBX solutions allow unlimited extensions with VoIP PBX functionality, DID numbers, call transfers, voicemail, and internal communication — making it the perfect business phone system for startups, enterprises, and call centers.
Employees access the PBX from any device — desktop IP phone, laptop softphone, mobile app, or web browser — from any location worldwide. Remote workers get identical features as office-based staff including extension dialling, presence status, call forwarding, voicemail access, and participation in call queues and conference bridges.
Configure sophisticated time-of-day and day-of-week routing rules, department-based distribution, hunt groups with configurable ring strategies (round-robin, least-recent, ring-all, memory), overflow escalation chains, failover routing, and holiday schedules — ensuring every call reaches the right person at the right time.
Build multi-level auto-attendant menus with custom audio prompts, DTMF keypress detection, and optional speech recognition. Route callers to departments, extensions, queues, or external numbers based on their input. Support for multi-language prompts, time-based IVR switching, and sub-menu nesting for complex organisational structures.
Every extension receives a dedicated voicemail inbox with configurable greeting, maximum message length, and storage quotas. Voicemail messages are automatically forwarded as email attachments with optional speech-to-text transcription — ensuring staff never miss important messages whether they are at their desk, on the road, or working from home.
Record calls on-demand, per-extension, or system-wide with encrypted storage and compliance-ready retention policies. Full Call Detail Record (CDR) reporting with searchable logs, filterable by date, extension, caller ID, disposition, and duration. Real-time dashboards show active calls, queue depths, and per-extension usage statistics.
Connect your PBX directly to our SIP trunking infrastructure for cost-effective PSTN connectivity with competitive per-minute rates to worldwide destinations. Support for concurrent channel scaling, caller ID management, failover trunk groups, and DID number provisioning — all configured and managed from within the PBX admin interface.
Set up departmental call queues (sales, support, billing) with configurable hold music, estimated wait time announcements, priority queuing, and skills-based agent matching. Callers hear position-in-queue updates and can request callbacks instead of waiting — reducing abandon rates and improving customer satisfaction scores.
All voice traffic encrypted with SRTP/TLS, SIP registration protected by fail2ban intrusion detection, encrypted storage for recordings and voicemail, role-based admin access controls, IP-based access restrictions, and DDoS mitigation. Infrastructure hosted in SOC 2 compliant data centres with automated backups and disaster recovery protocols.

Everything runs on our enterprise cloud infrastructure — you pay a predictable monthly fee with zero capital expenditure and no hardware depreciation.
Use SIP-compatible IP desk phones from any manufacturer, softphone applications on laptops and desktops, mobile apps on iOS and Android, or the WebRTC browser phone. One PBX system serves your entire organisation regardless of device preference, location, or network — office WiFi, home broadband, or cellular data.
Auto attendant, multi-level IVR, conference bridges, call queues with skills routing, voicemail-to-email with transcription, call recording, CDR analytics, presence management, and mobile twinning — all the features that Fortune 500 phone systems offer, delivered at a price point accessible to growing businesses starting at just $15/month.
The PBX admin portal allows business owners, office managers, and IT staff to add extensions, modify call routing, update IVR menus, manage voicemail settings, view call reports, and configure features through a graphical interface — no command-line access, no Asterisk dial plan syntax, and no specialised telecom training required.
Add 5 extensions or 500 extensions — the cloud PBX scales instantly without hardware upgrades, licensing renegotiations, or system restarts. As your business grows, opens new offices, or onboards remote teams, the PBX expands seamlessly to accommodate any number of users and concurrent calls.
NexGenVoice PBX Solutions integrates directly with the SIP devices, softphones, IP phones, CRM systems, and business tools your team already uses — no rip-and-replace required, no proprietary hardware lock-in, and no vendor-specific endpoints.
Explore what PBX technology is, how cloud-hosted PBX differs from traditional on-premise systems, why Asterisk and FusionPBX are the leading open-source platforms, and what factors determine the right PBX solution for your organisation's communication needs.
PBX (Private Branch Exchange) is a private telephone switching system used within an organisation to manage internal and external voice communication. A PBX allows employees to call each other using short extension numbers (e.g., dialling 101 instead of a full phone number), transfers calls between departments, routes incoming calls through auto-attendant menus, and provides shared features like voicemail, conference bridging, and call recording.
Traditional PBX systems required physical hardware — a PBX server cabinet installed in a telecom closet, connected to the public telephone network through PRI or analog lines, with proprietary desk phones wired to Ethernet switches throughout the office. These systems cost thousands to tens of thousands upfront, required specialised technicians for installation and maintenance, and could take weeks to provision or modify.
Cloud PBX replaces all of this hardware with software running on enterprise-grade servers in secure data centres. Phones connect over the internet using the SIP (Session Initiation Protocol) standard, and all PBX features — extensions, routing, voicemail, IVR — are delivered as a managed service. The result is dramatically lower costs, faster deployment, and the ability to support remote and distributed workforces that traditional PBX simply cannot accommodate.
The fundamental difference between cloud PBX and on-premise PBX is where the phone system software runs and who manages it. With on-premise PBX, the organisation purchases, installs, and maintains physical server hardware on-site — bearing full responsibility for security patches, software updates, backup procedures, hardware failures, and power protection. Capital expenditure is high (typically $5,000 to $50,000+ depending on scale) and ongoing operational costs include maintenance contracts, IT staff time, and eventual hardware replacement cycles.
Cloud PBX shifts the entire infrastructure to a service provider's data centre. The provider handles server provisioning, OS and application updates, security hardening, backup and disaster recovery, and 24/7 monitoring. Businesses pay a predictable monthly subscription with zero upfront capital cost, scale capacity on demand, and eliminate the risk of hardware obsolescence. Deployment that once took weeks happens in hours.
The cloud model also fundamentally changes geographic flexibility. On-premise PBX ties phone service to a physical location — if the office loses power or internet, phones go down. Cloud PBX with SIP endpoints allows employees to work from anywhere with an internet connection, receive calls on their business extension whether they are at home, in a co-working space, or travelling internationally — with identical feature access and call quality.
Asterisk, created by Digium (now Sangoma), is the world's most widely deployed open-source PBX software. First released in 1999, Asterisk powers an estimated 80% of all PBX systems globally — from small business phone systems to carrier-grade telephony platforms handling millions of concurrent calls. Its modular architecture supports virtually every telephony protocol (SIP, IAX2, ISDN, analog) and codec, making it extraordinarily flexible.
Asterisk's power lies in its dial plan language — a scripting system that can implement virtually any call routing logic, from simple extension-to-extension dialling to complex multi-site failover chains with time-based rules, database lookups, and external API integrations. However, this flexibility comes at a cost: Asterisk requires significant technical expertise to configure and manage, and its native management interface is command-line based.
This is why most Asterisk deployments use a management GUI on top — FreePBX being the most popular for single-tenant installations. NexGenVoice's engineers are Asterisk specialists who handle the entire technical layer, presenting businesses with a fully managed, professionally configured Asterisk PBX without requiring any in-house telecom expertise.
FusionPBX is a multi-tenant PBX management interface built on top of the FreeSWITCH telephony engine. Unlike Asterisk, which was originally designed as a single-tenant system, FusionPBX was architected from the ground up to support multiple independent PBX instances (tenants) on a single server — making it the platform of choice for service providers, resellers, and organisations managing phone systems for multiple branches or client companies.
FusionPBX provides a comprehensive web-based admin interface that makes it significantly easier to manage extensions, call routing, IVR menus, call queues, conferencing, and other PBX features compared to raw Asterisk configuration. Its object-oriented architecture separates domains, users, and devices cleanly, and it includes built-in support for features like call recording, fax-to-email, SMS messaging, and LDAP directory integration.
NexGenVoice recommends FusionPBX for organisations that need multi-tenant capabilities (managing separate PBX instances for different departments, branches, or client companies), prefer a graphical management interface over command-line configuration, or want the FreeSWITCH engine's known performance advantages for high-concurrency scenarios.
The shift to remote and hybrid work models has made cloud PBX essential rather than optional. Traditional on-premise phone systems were designed for a world where every employee sat at a desk connected to the office network — they fundamentally cannot provide full phone system features to employees working from home, co-working spaces, or while travelling.
Cloud PBX eliminates this limitation entirely. Employees register their SIP softphone (installed on their laptop or mobile device) to the cloud PBX over any internet connection and instantly receive their business extension, voicemail, call forwarding rules, presence status, and access to company call queues and conference bridges. A sales rep working from home answers calls exactly as they would at their office desk — callers see the same business number, hear the same IVR menu, and reach the same extension.
For hybrid teams splitting time between office and home, cloud PBX provides seamless continuity. An employee's extension follows them between locations — they simply launch their softphone wherever they are working. Office-based staff can use physical IP desk phones, while remote staff use softphones or mobile apps, all connected to the same PBX with identical features. This flexibility has become a competitive necessity for attracting and retaining talent in the post-pandemic workforce.
Choosing a cloud PBX solutions provider requires evaluating reliability, scalability, VoIP quality, SIP trunk integration, and support. NexGenVoice delivers hosted PBX systems with enterprise-grade performance, flexible pricing, and expert VoIP engineering support.
Support quality is the single biggest differentiator between PBX providers. Phone systems are business-critical — when they go down, revenue stops and customers are lost. Evaluate whether support is provided by actual VoIP engineers who can diagnose SIP registration issues, troubleshoot audio quality problems, and modify dial plans, or by tier-1 agents limited to password resets and basic account changes. NexGenVoice's support team consists entirely of experienced VoIP engineers available 24/7.
Additional evaluation criteria include: SIP trunk integration capability (can they provide competitive calling rates or do you need a separate trunk provider?), number porting experience (how smoothly do they handle carrier-to-carrier transfers?), scalability track record (can they demonstrate deployments at your target scale?), security practices (encryption, intrusion detection, compliance certifications), and contract flexibility (month-to-month vs long-term lock-in). NexGenVoice scores strongly on every dimension with 500+ PBX deployments, 99.9% uptime SLA, integrated SIP trunking, full number porting support, and no long-term contracts.
Replace your outdated on-premise phone system with a powerful, feature-rich cloud PBX from NexGenVoice. Setup is fast, features are unlimited, and expert support is available around the clock.
Everything you need to know about NexGenVoice PBX Solutions — from platform selection and extension scaling to number porting, security, and remote work capabilities.
PBX (Private Branch Exchange) is a private telephone network used within an organisation. It allows internal users to communicate with each other using short extension numbers and connects to the public telephone network for external calls. Modern PBX systems include features like auto-attendant (IVR), voicemail, call routing, call queues, conference bridging, and call recording. Cloud PBX delivers all of these features over the internet without any physical hardware on your premises — the PBX software runs on enterprise servers in secure data centres, and your phones connect via SIP over your existing internet connection.
Asterisk is the most widely deployed open-source PBX engine in the world, offering extraordinary flexibility through its dial plan scripting language and support for virtually every telephony protocol. However, Asterisk requires significant technical expertise to configure and is primarily managed through command-line interfaces or third-party GUIs like FreePBX. FusionPBX is a multi-tenant web management interface built on the FreeSWITCH telephony engine, designed from the ground up with a graphical admin panel that makes PBX management accessible without deep technical skills. FusionPBX excels in multi-tenant environments where separate PBX instances are needed for different departments, branches, or client companies. NexGenVoice deploys both platforms and recommends the right one based on your specific requirements, team capabilities, and scalability needs.
There is no hard limit on the number of extensions with our cloud PBX. We support deployments ranging from 5-extension small businesses to 1,000+ extension enterprise installations. Critically, our pricing model scales based on the number of simultaneous calls (concurrent channels) rather than extension count — meaning you can provision extensions for every employee, including part-time staff and seasonal workers, without additional per-extension licensing costs. A 50-person company with a maximum of 10 concurrent calls pays for 10 channels, not 50 extensions.
Yes. We handle full number porting from your current carrier, whether that is a traditional telecom provider, a cable company, or another VoIP provider. The porting process typically takes 5 to 15 business days depending on the losing carrier, and we coordinate the entire process including submitting port requests, providing required documentation (LOA, recent bill copy), and scheduling the cutover. Most importantly, we ensure there is no service interruption during business hours — the cutover is scheduled for a time window you specify, and we test all numbers before confirming the port is complete.
Absolutely. Cloud PBX is inherently designed for distributed teams. Remote workers install a softphone application on their computer or mobile device, register it to the cloud PBX over their home internet or cellular data connection, and instantly receive their full business extension with all features. They can make and receive calls using their business number, transfer calls to colleagues, join conference bridges, access voicemail, and participate in call queues — identically to office-based staff who may be using physical IP desk phones. Callers experience no difference whether the person answering is at a desk in the office or working from a home office in another city.
IVR (Interactive Voice Response) is an automated phone menu system that greets callers and routes them to the correct destination based on their input. When a caller dials your main business number, the IVR plays a recorded greeting (for example, "Thank you for calling ABC Company. For Sales press 1, for Support press 2, for Billing press 3") and then routes the call based on the keypress. Modern IVR systems support multi-level menus (sub-menus within menus), time-based routing (different menus during business hours vs after hours), custom hold music, estimated wait time announcements, and optional speech recognition for hands-free navigation. Both Asterisk and FusionPBX include full IVR capabilities that we configure and customise for your organisation.
No. Cloud PBX works entirely with software-based endpoints — softphone applications installed on computers, laptops, smartphones, and tablets. Popular softphones like Zoiper, MicroSIP, and built-in WebRTC browser phones provide full calling capabilities including HD voice, call transfer, conferencing, and presence status without any physical hardware. If you prefer the feel and reliability of a desk phone, any SIP-compatible IP phone from manufacturers like Yealink, Grandstream, Cisco, Polycom, or Sangoma works seamlessly with our PBX — we can recommend models based on your requirements and provide provisioning configuration so phones auto-configure when connected to your network.
NexGenVoice cloud PBX is protected by multiple layers of enterprise-grade security. All voice traffic is encrypted using SRTP (Secure Real-Time Transport Protocol) with TLS-encrypted SIP signalling, preventing eavesdropping or call interception. SIP registration is protected by fail2ban intrusion detection that automatically blocks IP addresses after repeated failed authentication attempts. Call recordings and voicemail messages are stored with encryption at rest. Administrative access is controlled through role-based permissions, and optional IP whitelisting restricts SIP registration to known networks. Our infrastructure is hosted in SOC 2 compliant data centres with DDoS mitigation, automated backups, and documented disaster recovery procedures. We also conduct regular security audits and apply patches promptly to address any identified vulnerabilities.
