The Ethernet Phone E(M)T-747 is a next generation IP Phone that provides a cost-saving solution for small business/home users on their telecommunication needs. The E(M)T-747 is following the open standard SIP/H.323 protocol to make sure that the user can easily install this IP phone on most of the existing VoIP (Voice over IP) services. By using the state-of-the-art DSP (Digital Signal Processing) technology, the E(M)T-747 delivers outstanding voice quality that is very comparable to the PSTN voice quality.
02. Why should I use E(M)T-747 IP Phone, instead of PSTN Phone ?
Cost In general, phone service via VoIP is free or costs less than equivalent service from traditional sources but similar to alternative Public Switched Telephone Network (PSTN) service providers.
Some cost savings are due to using a single network to carry voice and data, especially where users have existing underutilized network capacity they can use for VoIP at no additional cost. VoIP to VoIP phone calls
on any provider are typically free, whilst VoIP to PSTN calls generally costs the VoIP user.
Functionality VoIP can facilitate tasks that may be more difficult to achieve using traditional phone networks:
Incoming phone calls can be automatically routed to your VoIP phone, regardless of where you are connected to the network. Take your VoIP phone with you on a trip, and wherever you connect to the Internet, you can receive incoming calls. Free phone numbers for use with VoIP are available in the USA , UK and other countries from organizations such as VoIP User. Call center agents using VoIP phones can work from anywhere with a sufficiently fast Internet connection. Many VoIP packages include PSTN features that most Telco normally charge extra for, or may be unavailable from your local Telco, such as 3-way calling, call forwarding, automatic redial, and caller ID.
Mobility VoIP allows users to travel anywhere in the world and still make and receive phone calls:
Subscribers of phone-line replacement services can make and receive local phone calls regardless of their location.
03. What is meant by "NGN”? ?
Next-Generation Network is a generic term used to describe the emerging packet-based networks. Such networks feature mixed traffic types such as voice, video, and data, and each traffic type receives an appropriate class of service. Realizing such converged networks requires special-purpose technology in
the network, such as MPLS.
04. What is meant by "IP Phone” ?
Voice over IP (also called VoIP, IP Telephony, and Internet telephony) refers to technology that enables routing of voice conversations over the Internet or any other IP network. The voice data flows over a general-purpose packet-switched network, instead of the traditional dedicated, circuit-switched voice transmission lines.
05. What is the advantage to use IP phone than Skype ?
More stable communication quality
Lower communication cost
No need to change the using way.
