Enterprise Phone FAQ

Enterprise phone systems are a modern solution for the needs of modern businesses. Zoom Phone can help businesses consolidate, simplify, and future-proof their communications systems in one straightforward transition. By combining voice, video, conferencing and even SMS (available on Zoom Phone in December 2020) into a single platform, Zoom Phone cuts down on unnecessary complication in your communications network.

For multinational firms, the benefits of enterprise phone systems are even greater. By enabling firms to consolidate carriers and communications providers on a global scale, Zoom Phone makes managing enterprise-level communications as simple, seamless and cost-effective as possible.

Yes. Zoom Phone offers a Bring Your Own Carrier option. This allows firms to opt into a hybrid model, which gives them access to all of Zoom Phone’s advanced features, while allowing them to keep their existing provider’s contracts, calling rates, and phone numbers. This also allows for a more gradual transition to a fully cloud-based telephone system.

Yes - Zoom Phone supports phone number porting from your current provider. Our system makes it easy to migrate existing phone numbers, as well as procure new numbers. The specific process depends on your current provider. Our team can walk you through the porting process during signup.

Transitioning from legacy PBX to an enterprise phone system is a multi-step process. Our onboarding team can help make the transition easier, but here is an overview of the process that most firms will follow:

  • Inventory & Assess - Start by taking an inventory of existing hardware, existing phone lines, number of employees, business locations, etc. You will also want to assess current bandwidth availability, and estimate how the transition to VoIP will affect connectivity speeds and bandwidth usage. It’s helpful to have a clear idea of what the current network looks like, and what needs the firm will have when transitioning to enterprise VoIP.
  • Collaborate & Estimate - On the enterprise level, a transition to business VoIP will likely require collaboration between several departments in the firm. To make the transition as smooth as possible, fully evaluate LAN or WAN reliability, bandwidth availability, network performance, and any other relevant factors, before migrating to enterprise VoIP.
  • Contact Sales - Once a firm’s current telephony network has been inventoried and assessed, it’s time to contact Zoom Phone Sales. For enterprise clients, we recommend contacting sales directly for help putting together a personalized transition plan.
  • Port Numbers - Next, the firm will need to begin the porting process to migrate existing phone numbers to the new VoIP provider. Zoom Phone Professional Services can help with this process, but typically the firm will need to contact their existing provider to begin porting.
  • Procure Hardware - In many cases, the next step will be to procure IP-enabled telephone hardware. Depending on the desired setup, this could include new desktop office phones, conference phones, or simple headsets for VoIP calls over office computers. For lower upfront costs, firms may consider utilizing Zoom Phone Hardware as a Service.
  • Configure & Customize - Working together with in-house IT and Zoom Phone’s support team, firms can move on to configure and customize their new enterprise VoIP system. This includes configuring physical hardware and network components, as well as customizing virtual features of Zoom Phone.
  • Schedule Cutover - Once the new system is configured properly, you can schedule a cutover day for the full transition to VoIP. Depending on the size of the firm and network requirements, this may take place immediately, or in a multi-phase process.

Remember - our dedicated Enterprise Sales Team is here to help. If you have questions about making the transition from PBX to business VoIP, contact us today.

Not necessarily. Zoom Phone is compatible with select desktop office phones. Zoom also supports the use of “softphones”, meaning employees can make calls directly from their office computers using inexpensive headsets. Zoom Phone Hardware as a Service is another viable option that allows firms to order hardware directly from Zoom, with virtually no upfront costs.
