Frequently asked questions

What should a call center look for in a phone system?
The essentials are inbound call queues, IVR/auto-attendant routing, call recording, live analytics and CRM integration. Headline price matters less than whether the routing and reporting fit how your team actually works.
Is a business phone system the same as contact center software?
They overlap. Many business phone providers offer a contact-center tier with advanced queueing, workforce and omnichannel features. This page ranks core business phone plans by their call-center-relevant capabilities; heavy contact-center needs may push you to a dedicated tier.
Does call recording come standard?
Not always — call recording and advanced analytics often sit in a higher tier rather than the entry plan. Check the tier that includes the routing and recording features your center needs, not just the cheapest one.
