What is OTT and Voice over Broadband?

OTT and Voice over Broadband (VoBB) services provide consumers and businesses with the ability to leverage their Wi-Fi, 3G and broadband Internet connectivity for inbound and/or outbound long distance calling with greater control and features as well as superior voice quality and redundancy in comparison to the traditional PSTN network. By delivering voice services over an all IP-network carriers are no longer shackled by the limitations of the traditional networks of the past so they are free to offer next-generation features like presence, personalized call-forwarding, colored ringtones and CD quality high-definition voice.

Phone numbers in an IP-network are not fixed to a particular geographic location so subscribers now have the freedom to move their device and/or service to any location they desire.  The OTT and Voice over Broadband service carries its identity with it no matter where and what device is registered so subscribers can receive, place and manage their communication services from anywhere in the world.  Connecting a telephone or softphone is plug-and-play today with service providers pre-provisioning the equipment for immediate use upon arrival/connection.  Since the feature-set is delivered over IP there are no complicated configuration settings to wade through and there is complete end user empowerment for account and call control management via the ubiquitous web.

Service providers deploying next-generation SIP-based OTT and VoBB platforms can offer their customers creative billing plans and a broad range of devices and configurations when utilizing their service.  Devices such as ATAs and IP phones, as well as desktop and mobile softphones, give consumers a wide range of choices and flexibility options while driving service usage and consumer loyalty when calling from home, work, or on the road.
