Voice Over IP - Dial-Tone Reliability

The Solution

Voice over IP (VoIP) is a technology that allows voice transmissions to travel over an IP network. A VoIP system depends on robust DHCP service as part of an IP infrastructure. Without such an infrastructure, IP telephony will fail. BlueCat Networks provides an integrated approach to VoIP that allows you to rapidly improve network scalability, reliability, and ease of use without compromise to security and high availability. Delivered as purpose-built appliances, Proteus and Adonis fit easily into existing corporate networks and provide many benefits.

The Challenge	How BlueCat Provides the Solution
You need to ensure availability and quality of service for your VoIP services.	BlueCat offers a number of redundant solutions including Crossover High Availability (XHA) and DHCP failover to ensure that your VoIP endpoints can always obtain an IP address.
Adding Voice Over IP to your network doubles IP allocation requirements overnight.	You can manage your VoIP networks regardless of the number of endpoints. Proteus scales to support millions of IP addresses.
Rolling out VoIP significantly increases the complexity of your DHCP infrastructure as different devices require their own unique options. You would like to reduce the complexity of DHCP settings related to VoIP.	Proteus includes easy-to-use tools such as custom options and vendor profiles to setup advanced configurations

VoIP handsets use TFTP to manage their software. You need a solution that includes built-in a TFTP service to manage the firmware on VoIP handsets.	BlueCat appliances and virtual solutions include a built-in TFTP service, so you don’t need to install a separate TFTP server.
You are looking to adopt ENUM in your organization to take advantage of ENUM’s ability to use standard phone numbers to access a variety of internet services however; you have found configuring NAPTR records to be complex.	BlueCat provides Proteus provides a simple and elegant solution for ENUM which removes its inherent complexity.

VoIP & Unified Messaging Solutions

No IPs, no network, no phone calls. Learn why DNS and DHCP are fundamental services required for VoIP. Each time an IP telephone joins the network, the phone requests an IP lease (DHCP) in addition to when you dial a phone number, DNS and ENUM are needed to translate phone numbers into IP addresses. Learn why DNS and DHCP management are critical to keeping your VoIP network highly available.
