Explained by experts:

Why UCaaS?

Some companies, especially smaller companies, use UCaaS to avoid investment costs (capex). They prefer a flexible and operating cost (Opex) model for their UC service.

With UCaaS, you can react quickly to the circumstances of your company without having to make large investments and complex adjustments to your company infrastructure. For example, if you need external staff for a project at short notice, you can simply add additional extensions for this period and remove them again once the project is complete. Thanks to the great scalability and flexibility of UCaaS, this is all standard.

What advantages does UCaaS offer?

Technical outline of UCaaS (Unified Communications as a Service) with functions such as video telephony, messaging, telephony, CRM integration, screen & file sharing, collaboration, presence, mobility and IVR.

The elimination of the various communication applications also reduces security risks. As a user of UCaaS solutions, you no longer need additional freeware programs for your desired communication services, which can lead to security risks. All your applications run via a centrally administered unified communication client.

Types of UCaaS architectures

If you prefer single-tenancy, you will receive a dedicated software platform that can be integrated and adapted to your on-site applications. Single-tenancy, also known as multi-instance, keeps customer data separate from each other and is therefore considered very secure and reliable. In the event of a failure of another customer’s software instances, your customer data remains unaffected.

Multi-tenancy is more cost-effective as customers share a single software platform (multi-tenancy) with extended support and increased redundancy. The UCaaS provider hosts this software instance in a data center and carries out all upgrades. However, multi-tenancy is more limited in terms of adaptability and flexibility than single-tenancy.

Hybrid solutions combine on-premise components with cloud applications. Reasons for this may be administrative or security-related requirements to keep certain applications at your own location, e.g. an existing PBX or internal systems.

UCaaS – FAQs

What is UCaaS and why do businesses need it?

UCaaS (Unified Communications as a Service) bundles telephony, video conferencing, chat, screen sharing, file exchange and presence in one cloud platform. Instead of multiple separate tools such as phone, Skype, WhatsApp and email, employees use one integrated application across all devices. UCaaS is particularly relevant for companies with distributed teams, home office models or international sites. Usage is licensed per user, with no on-premise server infrastructure required.

What is the difference between UCaaS and a cloud phone system?

A cloud phone system focuses primarily on voice communication: calls, voicemail, call forwarding and queues. UCaaS covers the same plus video, chat, collaboration and integration with business tools such as CRM or Microsoft 365. UCaaS is the natural evolution of cloud phone systems towards collaboration. Many providers such as RingCentral, 8×8 or Microsoft Teams position their solutions as UCaaS today, even though telephony remains the core.

Which UCaaS providers are leading the market?

Leading UCaaS providers are Microsoft Teams Phone, RingCentral, Zoom Phone, 8×8, Webex by Cisco, Dialpad and Vonage. For German companies with Microsoft focus, Microsoft Teams is usually the first choice. RingCentral and 8×8 stand out for international footprints. Zoom Phone is relevant for companies that already rely heavily on Zoom Meetings. Webex remains relevant for classic Cisco environments. SAVECALL creates an objective comparison matrix matching the existing IT strategy.

What does UCaaS cost per user?

UCaaS licences typically range from 12 to 30 euros per user monthly, depending on features. Basic packages with telephony, video and chat start at 12 euros. Standard packages with extended collaboration and integration features cost 18 to 25 euros. Enterprise packages with call centre functions, analytics and compliance features range from 25 to 50 euros. Through the SAVECALL procurement pool, you secure conditions 15 to 30 percent below list price.

How does UCaaS integrate with existing IT systems?

Modern UCaaS platforms offer APIs and standard integrations for CRM systems such as Salesforce, HubSpot or Microsoft Dynamics, for ticketing systems such as Zendesk and ServiceNow, and for productivity suites such as Microsoft 365 and Google Workspace. Click-to-call from the CRM, automatic call logging and screen pop-ups on incoming calls are standard. SAVECALL plans the integration holistically and configures APIs, single sign-on and compliance settings as part of the implementation project.

How quickly can a UCaaS solution be deployed?

A basic implementation for 25 to 100 users is productive within 4 to 8 weeks. More complex setups with multi-site rollout, CRM integration, call centre functions or international scaling take 8 to 16 weeks. For full migration from an existing on-premise system, plan for porting, parallel operation and training. SAVECALL handles requirements analysis, provider selection, configuration, rollout and user training end-to-end.
