Phone solutions still play an important part in business communication – and how you deliver it says a lot about your organisation. Whether your team is in the office, working remotely, or spread across multiple sites, Fastcom voice solutions keep people connected clearly, reliably and cost effectively, including New Zealand’s critical emergency services with complex, critical call centre environments.

From modern SIP and VoIP solutions, hosted and onsite PBX systems, simple and complex call centres and support for businesses still running legacy PSTN infrastructure, Fastcom has the expertise to deliver the right voice solution for your business. And if those acronyms mean nothing to you, don’t worry – the Fastcom team understands voice from the ground up and will get you sorted.

SIP trunking and VoIP have transformed business telephony – delivering the features and flexibility of a modern phone system at a fraction of the cost of traditional PSTN lines. Fastcom’s Managed SIP/VoIP service runs over our own network infrastructure, giving you the call quality, reliability and control that a resold product simply can’t match.

Whether you’re replacing aging systems, consolidating multiple sites onto a single voice platform, or simply looking for a better, more cost-effective way to make and receive calls, Fastcom’s managed SIP/VoIP solution gives your business a modern, scalable voice foundation – backed by a team that manages it end to end.

  • HD call quality: Voice traffic runs over Fastcom’s managed network with QoS prioritisation – delivering consistently clear, high-definition calls without the dropouts or delays of lesser solutions.
  • Significant cost savings: Replace expensive ISDN and PSTN line rentals with cost-effective SIP trunks – reducing your monthly call costs and line charges substantially.
  • Scalable capacity: Add or remove channels instantly as your business needs change – no waiting for physical line installations or paying for capacity you don’t use.
  • Multi-site consolidation: Bring all your sites onto a single managed voice platform to simplify administration, reduce costs, and enable seamless internal calling between locations.
  • Work from anywhere: Staff can make and receive calls on their business number from any location and device, supporting hybrid and remote working without compromising professionalism.
  • Fully managed: Fastcom manages your SIP/VoIP environment end to end – provisioning, monitoring and supporting your voice infrastructure so you don’t have to.

A PBX (Private Branch Exchange) is the engine room of your business phone system, managing internal and external calls, hunt groups, voicemail, auto-attendants and more. Fastcom delivers PBX solutions both as a fully hosted cloud service and as an onsite deployment, giving you the flexibility to choose the model that best suits your business, your infrastructure, and your preferences.

Whether you prefer the simplicity and reduced overhead of a hosted PBX, or the control and customisation of an onsite system, Fastcom has the expertise to design, deploy and manage your solution. We support leading platforms including Mitel MX-ONE, and our team understands the nuances of enterprise telephony, from handsets to trunk lines.

  • Hosted or onsite – your choice: We deliver PBX both as a hosted cloud service and as an onsite deployment – so you choose the model that fits your business, not the one that suits us.
  • Enterprise-grade features: Hunt groups, auto-attendants, voicemail, call recording, conferencing and more – full-featured telephony that gives your business a professional presence.
  • Multi-site capability: Connect multiple offices under a single PBX platform with seamless internal dialling, shared resources, and centralised management across all locations.
  • Softphone & mobile integration: Extend your PBX to laptops, smartphones, and tablets, giving your team full phone system functionality wherever they’re working.
  • Fully managed & supported: Fastcom manages your PBX environment, handling moves, adds, changes, upgrades and support so your phone system just works.
  • Scalable as you grow: Add users, extensions, and features as your business expands without replacing your entire phone system every time needs change.

Your contact centre is often the first impression your customers have of your organisation. Whether you’re running a small inbound team or a multi-site contact centre operation, the technology behind it needs to be reliable, flexible and built around the experience you want to deliver. Fastcom provides end-to-end call centre solutions that give your team the tools to handle every interaction professionally and efficiently.

From intelligent call routing and queue management through to real-time reporting, workforce management, and integration with your CRM and business systems, Fastcom designs and manages call centre environments tailored to your operation. Hosted in the cloud or deployed onsite, our solutions are built on the same reliable infrastructure that underpins everything we do – giving you the performance and uptime your customers expect.

  • Intelligent call routing: Route calls to the right agent, team or queue based on skills, availability, or customer data – reducing wait times and improving first-call resolution rates.
  • Real-time reporting & analytics: Live dashboards and detailed reporting give supervisors full visibility of queue performance, agent activity, and service levels so you can manage proactively, not reactively.
  • AI agents & virtual assistants: AI-powered virtual agents handle routine enquiries, triage calls, and resolve common requests automatically to reduce agent workload, cut wait times, and deliver 24/7 customer service without increasing headcount.
  • Microsoft Teams integration: Seamlessly integrate your call centre with Microsoft Teams, enabling agents to collaborate, transfer calls, and escalate to subject matter experts directly within the Teams environment your people already use.
  • Built-in APIs to common CRM systems: Pre-built integrations connect your call centre to leading CRM platforms including Salesforce, HubSpot, Microsoft Dynamics, and more, giving agents instant access to customer history, open cases, and account details before the conversation begins.
  • Remote & hybrid agent support: Agents can work from the office, from home, or across multiple sites with the same call quality, tools and reporting regardless of where they’re based.
  • CRM & system integration: Integrate your call centre platform with your CRM, ticketing system, or business applications to give agents the customer context they need before the call is even answered.
  • Call recording & quality management: Record and review calls for training, compliance and quality assurance with secure, searchable storage and easy access when you need it.
  • Scalable to your operation: Whether you have five agents or five hundred, our call centre solutions scale with your operation, adding capacity, features, and sites without replacing your entire platform.

Many New Zealand businesses still rely on traditional PSTN (Public Switched Telephone Network) infrastructure – and there are good reasons why a transition to modern voice may not be right for you today. Fastcom provides expert support and management for legacy PSTN voice services, ensuring your existing infrastructure continues to perform reliably while you plan your path forward.

We understand that migrating away from legacy voice is a significant undertaking – one that needs to be planned carefully, at the right time, and in the right way for your business. Fastcom can manage your PSTN environment today and, when you’re ready, guide you through a structured, low-disruption migration to modern SIP or hosted voice – all at your pace, on your terms.

  • Expert legacy support: Our team has deep experience with traditional PSTN infrastructure: diagnosing faults, managing lines, and keeping your existing system running reliably.
  • Proactive monitoring: We monitor your PSTN infrastructure and act on issues quickly – minimising disruption and keeping your lines available when your business needs them.
  • Clear migration roadmap: When you’re ready to move to modern voice, Fastcom can provide a structured migration plan that minimises disruption and ensures a seamless transition for your team.
  • Migrate at your pace: There’s no pressure to move before you’re ready. We support your legacy infrastructure for as long as you need it, while helping you plan a transition that works for your business.
  • Number portability: Keep your existing phone numbers when you migrate – there’s no need to change printed materials, websites or customer-facing contact details.
  • One team for old and new: Fastcom supports both legacy and modern voice so you have a single team managing your entire voice environment throughout your transition, not two providers to coordinate.

Fastcom has been certified under ISO27001:2002 and independently audited to confirm we meet SOC2, HIPPA and NIST CSF 2.0 standards – giving you confidence that your data and systems are in safe, audited hands.
