Frequently Asked Questions

Common questions about UCaaS and VoIP phone systems

What is UCaaS and why do businesses need it?

UCaaS (Unified Communications as a Service) is a cloud-based platform that combines voice calling, video conferencing, team messaging, and file sharing into one subscription. Businesses need it to replace aging on-premise phone systems, reduce IT overhead, enable remote work, and cut communication costs. Most mid-market businesses switching to UCaaS save 30-50% compared to legacy PBX systems.

How long does it take to migrate to a new UCaaS platform?

Most UCaaS migrations take between 30 and 90 days depending on business size and complexity. Cloud-first providers like PanTerra Networks advertise average migration timelines of 67 days with zero downtime. The fastest migrations are typically small businesses with under 50 users, which can switch in as little as one week.

What should I look for when comparing UCaaS providers?

When comparing UCaaS providers, focus on five key factors: (1) uptime SLA -- look for 99.999% or better, (2) pricing transparency -- watch for hidden fees at renewal, (3) compliance features -- HIPAA and FINRA if required, (4) mobile calling capability -- critical for remote teams, and (5) contract terms -- avoid multi-year lock-ins where possible.

What is the average cost of UCaaS per user per month?

UCaaS pricing ranges from $15 to $65 per user per month. Entry-level plans start around $15-25 and include basic calling, voicemail, and video meetings. Mid-tier plans at $25-40 add features like call recording and analytics. Enterprise plans at $40-65 include contact center tools, compliance recording, WFM, and dedicated support.

Can I keep my existing phone numbers when switching to UCaaS?

Yes -- number porting is standard with all major UCaaS providers. The process takes 2-4 weeks on average and allows you to transfer existing business phone numbers to the new platform. Most providers offer temporary forwarding so you never miss a call during the transition.
