WAN – FAQs
A cloud phone system (hosted PBX) is delivered as a service over the internet. Instead of on-premise hardware, voice services run in the provider’s cloud. Switching makes sense when your ISDN system is being retired, you have distributed teams, you want to use Microsoft Teams for telephony, or the maintenance costs of your on-premise system become too high. Benefits include monthly fees without capital investment, automatic updates and full location flexibility.
MS Teams Phone integrates business telephony directly into Microsoft Teams. Employees make calls from the familiar collaboration interface, without a separate system or app. A traditional PBX is physically located in the company, uses dedicated endpoints and is administered separately. Teams Phone saves hardware costs, simplifies management and supports hybrid work better. For pure hardphone environments or advanced call centre requirements, dedicated cloud PBX solutions often remain the better choice.
UCaaS (Unified Communications as a Service) combines telephony, video, chat, presence and file sharing in one cloud platform. Instead of separate tools, employees use one integrated solution across all devices. Companies benefit from unified usability, lower licence costs, higher productivity and better reachability. UCaaS is particularly relevant for businesses with distributed teams, home office models or international collaboration
Costs typically range from 5 to 15 euros per extension per month, depending on features. Basic packages start at 5 euros and include telephony and voicemail. Fully featured UCaaS packages with video, chat and call centre functions range from 12 to 20 euros. Add one-time setup costs and possibly new devices or headsets. SAVECALL objectively compares over 80 carriers and finds the most cost-effective solution for your requirements.
Modern cloud voice providers use TLS and SRTP encryption for signalling and media, redundant EU data centres and ISO 27001 certifications. For strict compliance requirements, solutions with German data centres and GDPR-compliant data processing are available. Risks usually arise not with the provider but with poorly configured endpoints or insecure networks. SAVECALL reviews security concepts and integrates SASE or zero trust architectures when needed.
A typical cloud PBX project takes 4 to 12 weeks from contract to go-live. With pure number portability and no new hardware, it goes faster. Larger migrations with multi-site rollouts, call centre setup or MS Teams integration take 8 to 16 weeks. SAVECALL handles project planning, carrier coordination, porting and training end-to-end, ensuring the migration runs without downtime.
