Voip Phone Standards

This standard provides techniques for objective measurement of electroacoustic devices used for speech communications, including communication devices also used for multimedia applications. Application is for devices that are primarily used closely coupled to the ear. Aspects of devices with...

This service definition is compliant with [1]. It defines a service type referred to herein as Messaging service. The Messaging service is a UPnP service that allows control points to use the messaging features provided by a Telephony Server (TS) or a Telephony Client (TC). It provides in the UPnP...

This standard applies to both wireless communications devices (WDs) and hearing aids. It sets forth uniform methods of measurement and parametric requirements for the electromagnetic and operational compatibility of hearing aids and WDs, including cellular phones, personal communications...

This revision to the Recommendation1 defines managed Internet Protocol television (using UDP) (IPTV), IPTV and VoIP stream for well managed, partially managed and un-managed network conditions. It also defines the remaining residual unmanaged bandwidth (Internet services) which are typically...

This revision to the Standard defines managed IPTV, IPTV and VoIP stream for Well Managed, Partially Managed and Un-Managed Network conditions. It also defines the remaining residual unmanaged bandwidth (Internet Services) which are typically used for TCP applications. The main difference...

This document provides definitions for a metric that can be used to gauge the ability of an IP network to deliver transaction services in an acceptable manner. A transaction is defined as an IP network session involving a sequence of related information exchanges and processing operations designed...

It is becoming increasingly apparent that all forms of communication-including voice-will be transmitted through packet-switched networks based on the Internet Protocol (IP). Therefore, the design of modern devices that rely on speech interfaces, such as cell phones and PDAs, requires a...

This Standard specifies the minimum requirements for media and protocol-specific call control interoperability, acoustic performance, telephony feature support, safety, electromagnetic compatibility, and environmental performance of VoIP Feature Telephones operating in a business environment...

This Standard defines a set of organizationally-specific IEEE 802.1AB TLV extensions and a related MIB module, for the purpose of improved deployment properties and multi-vendor interoperability between VoIP endpoint devices and IEEE 802 networking infrastructure elements. Where required for...

Emergency calling solutions exist to retrieve user's information and geolocation for both E.164 and PLMN telephone networks: An E.164 emergency call relies on the public phone directory to retrieve information; A PLMN emergency call relies on Cell Ids and radio triangulation process to...
