Broadband Net Phone Solution
System overview |
When currently establishing NGN system and developing business
of user’s speech connection, the telecom carriers are always
conflicted with the problems of shortage on IP transmission
circuit, long construction period or difficult equipment
maintenance, etc. Also, since NGN system requires large
investment and is relative immaturity, it will not be an
effective profit mode in a short period.
With the popularization of Internet and network access through
broadband, VOIP net phone technology has grown to be an
important means of developing speech business for the telecom
carriers, which is an available existing source. It is actually
a net phone comprehensive operation system to rapidly develop
the users, increase the speech business and even can smoothly
transit to NGN system.
EWAY, by closely following up the latest technology of soft
exchange to meet the practical operation demands of carriers in
the current stage and combining years of experience in
large-scale VOIP network construction, releases EwayNet™
“EwayNet” net phone comprehensive operation system which
provides the carriers with overall system solution of user’s
speech access, IP phone supermarket or group network through the
Internet / IP Metropolitan Area Network.
System application solution
Since the medium/small-size enterprises users have not many
staff yet it is definitely a large quantity, the telecom carrier
will have difficulty in special line access. And though net
phone enables the telecom carriers to rapidly collect the call
charge through IP Metropolitan Area Network / Internet, mode of
this kind has the disadvantages of difficult installation &
maintenance, no speech penetration within the fire wall or no
gatekeeper of the equipments.
EwayNet™ “EwayNet” system overall solves the operation and
technology problems of bi-directional speech penetration within
fire wall/ agency server, equipment gatekeeper of private
network, “Plug- and-play” of net phone IAD equipments, level
account management of call charge agents and Web enquiry of call
list. It is an intact means of “Operation, maintenance,
management and profits-making available” for the telecom
carriers to carry out the speech business through the Internet /
IP Metropolitan Area Network.

the “Plug-and-play”.
The EWAYTrans? “EWAYTrans” patent technology released by EWAY
successfully solves the problems of fire wall and NAT
restrictions on traditional IP phone communication. That is,
without any change on the network configuration, on the
condition that the user can visit the Internet, the terminal
equipment of IAD can freely call and manage which is really the
“Plug-and-Play” of IAD equipment free from troubles of
installation & maintenance.
Another important feature is that the system can offer
long-distance access operation module for call charge agents
