What it is

The short version

Hosted VoIP and Unified Communications as a Service replace legacy phone systems with cloud-delivered voice, messaging, video, and collaboration. There is no on-premise PBX to maintain and no per-site hardware refresh cycle to plan around.

We source across RingCentral, 8x8, Nextiva, Zoom Phone, Webex Calling, Dialpad, GoTo, and direct SIP providers. Each one has strengths in price, contact center features, international coverage, or integration with the apps your team already uses.

Where it fits

Typical use cases

Office migrations

Replace aging PBX systems with a single cloud platform that follows users between office, home, and mobile.

Multi-site companies

One dial plan, one admin console, and one bill across every location.

Contact centers and sales teams

Skill-based routing, call recording, real-time dashboards, and CRM integration with Salesforce, HubSpot, and Zendesk.

Remote-first teams

Native softphones, mobile apps, and messaging that work the same wherever the employee sits.

What you get

From Critical IP, end to end

  • Discovery of current call flows, hunt groups, voicemail, and integrations so nothing breaks at cutover.
  • Number porting, e911 registration, and provisioning of phones, headsets, and softphone clients.
  • Carrier and platform comparison with side-by-side pricing across all major UCaaS vendors.
  • Adoption training and post-cutover support so the help desk is not flooded the morning after.
FAQ

Common questions

Can we keep our existing phone numbers?
Yes. We coordinate the port from your current carrier, schedule the cutover after hours, and keep the legacy service live until porting completes successfully.
Will hosted voice work if our internet goes down?
Mobile apps and softphones automatically fall back to LTE. With SD-WAN and a secondary circuit, desk phones stay up through most local outages.
What about international offices?
Most platforms offer in-country phone numbers and unlimited calling plans across the US, Canada, and dozens of other countries. We pick the platform that matches your geography.
