Switching to VoIP is Easier Than You Think: A Step-by-Step Migration Guide

Written by Everett Kildare · Feb 12, 2026 · 7 min read

Many businesses delay switching to VoIP because they assume it's a complex, disruptive process. In reality, most migrations are completed in under a week with zero downtime.

Step 1: Assess Your Current Setup

Take inventory of your existing phone lines, extensions, and features. How many concurrent calls do you handle? What features do you use? This helps size your new system correctly.

Step 2: Check Your Internet

Internet connectivity

VoIP requires a stable internet connection. Each concurrent call needs roughly 100 Kbps of bandwidth. For most businesses with standard broadband, this is easily achievable. WOCOM performs a free network assessment before any migration.

Step 3: Port Your Numbers

You keep your existing business phone numbers. WOCOM handles the porting process with your current provider — it typically takes 5-10 business days.

Step 4: Plug In and Go

IP phones arrive pre-configured. Plug them into your network, and they automatically connect to WOCOM's cloud. Your team can start making calls immediately.

Step 5: Training (15 Minutes)

Modern IP phones are intuitive. Most users need just 15 minutes of training to feel comfortable. Features like transfer, hold, and conferencing work the same way — just with more capabilities.
