How to Choose the Right Phone System Plan: From Starter to Enterprise

Number of extensions, concurrent calls, and monitoring/reporting needs are the three most important criteria when comparing plans.

Picking the wrong plan — too small for your needs or with excess unused features — wastes money either way. Here’s how to approach choosing the right one.

Estimate extensions and concurrent calls#

Extensions correspond to the number of users who need their own internal number; concurrent calls is how many calls can happen at once. A small team that rarely calls out usually fits a basic plan; a sales/customer service team on constant calls needs a plan with a higher concurrent-call limit.

Determine whether you need agent/supervisor roles#

If your business runs on a queue model (multiple agents answering calls from a shared hotline, with a supervisor monitoring), you need a plan that supports the right number of agents/supervisors — this is the main difference between the Business plan and the Contact Center plan.

DECISION GUIDE

Quick Decision Tree: Which Plan Fits You Best?

Answer 3 simple questions to determine the optimal VitaPBX package.

1
Team size & basic communication need?
1 - 5 staff:
Choose Starter Plan. Low cost, full WebRTC calling.
10 - 30 staff:
Choose Business Plan. IVR menu, call recording, queues.
2
Dedicated customer service / telesales queue?
Yes (Need ACD, Live Wallboard & Supervisor Roles):
Choose Contact Center Plan. Full agent lifecycle, queue analytics, barge & whisper monitoring.
3
Custom CRM integrations or 50+ extensions?
Custom / High Volume:
Contact for Enterprise Plan. Dedicated SIP trunks, custom Asterisk dialplan, and SLA guarantees.

Consider your call recording storage needs#

Call recordings serve training and dispute resolution, but storage capacity/retention period differ between plans. Businesses with long-term retention compliance requirements should check this spec closely before signing up.

When to request a quote instead of picking a listed plan#

For heavy customization needs (custom integrations, extension/agent counts beyond listed plans), the Enterprise contact-for-quote plan fits better since it allows configuration to your specific requirements.
