The VoIP basics every enterprise should know

Last updated:May 2015

Editor's note

Many organizations are transitioning away from traditional voice services in favor of Voice over IP (VoIP). VoIP delivers voice traffic over the Internet rather than the legacy public switched telephone network (PSTN), which offers organizations cost savings, more advanced features and other benefits. But implementing VoIP is no small task and enterprises must be prepared to migrate their voice services with minimal disruption.

This essential guide covers the VoIP basics, from building the right infrastructure to taking security measures, to ensure your enterprise is prepared to successfully transition to VoIP.

1Building a VoIP infrastructure

VoIP requires a robust infrastructure and quality of service to support its bandwidth needs. An enterprise that hasn't prepared its infrastructure will end up with call quality issues like jitter and latency. Learn the VoIP basics to help you build an infrastructure that can handle all of VoIP's requirements.

2Moving VoIP to the cloud

Many enterprises opt for cloud-based VoIP when migrating from the PSTN to cut costs and take advantage of the expertise of a cloud service provider. But moving VoIP to the cloud is more complex than it seems. Learn how to prepare your network and clear the hurdles that prevent cloud VoIP deployments.

3Securing VoIP

Enterprises that transition to VoIP face new security threats that were not common on legacy voice systems, like telephony denial of service attacks, toll fraud and VoIP hacking. But there are steps IT can take to protect their organization from attacks. Learn how to protect your enterprise from VoIP security threats.
