Nowadays, there are many VoIP devices, specially for low-end products of 1 to 2 ports gateways, which use special-purpose SoC (System On Chip) applied by CPU with DSP on the same chip or not use DSP to execute voice compression, echo cancellation and so on by main CPU's processing ability only.

The soft CODEC is used instead of DSP that this kind of product's price is lower as to reduce the use of components, but the performance is limited as the cost down of hardware, and as a result that the most end products are produced by Turn Key's program provided by chips' suppliers that just can provide simple function and become very difficult to produce customized products or debug program.

ALLWIN's entire OneInGate VoIP series used specific powerful performance of 32-bit network processor and voice signal processes of DSP according to different deployments' devices no matter for 1 port of TA, IP phone, E1 trunk gateway.

Therefore the performance, the sound quality and the stability are much more competitive with the other low cost of VoIPs' devices.

ALLWIN designs all of product lines by many years of rich design experiences, no matter on the design of hardware, communication protocol, or Web UI; and not only to accept the "Me too" products of chip vendor's turn key.
Also, ALLWIN provides the standard Web UI on IP phones, various ports of Gateways, E1 PRI trunk; therefore it's easier for clients to use all of ALLWIN's product lines after users are familiar with one of any products' Web UI.

Generally, the construction of software from bottom tier to top tier is RTOS (Real Time Operation System)>SIP protocol>application>WEB UI for other VoIP devices' suppliers and their every tier of software is compiled by C language with API.

Therefore, the system would shut down if any tier of software is on trouble by this kind of traditional design; and any modification need to be re-compiled, then link for use. If not consider the inside process from bottom to top tiers of API's for the modification of any tier of software that it will cause the system shut down as well. Hence, the traditional design by C language and API oriented will be difficult to meet the application of customized VoIP devices.

As ALLWIN understands the design way and its limitation, ALLWIN's R&D team spent around USD0.35 million and two years to design the newest construction of SW and HW after getting the R&D project's sponsor of "Ministry of Economic Affairs, R.O.C.".

The project of OneInXML uses specific XML parser to process the high lever's application of top tier of SW, such as CODEC procedure and Web UI.
Therefore, ALLWIN can meet and provide OEM/ODM service due to the separate process of application's tier and protocol's tier to assure the stability and easy to extend the application of devices.

As the CODEC is processed by the specific DSP for all of ALLWIN's product lines, therefore the build-in 32 bit network processor has enough ability to process the internet router functions besides the VoIP functions, these powerful functions include:

WAN connection
Besides support DHCP client. Static IP, PPPoE for accessing network, but also support PPPTP, L2TP, MAC Cloning and so on.



NAT
Besides support basic NAT and DHCP Server, but also support Virtual Server, Special Application mapping, Port mapping, ALG, DMZ and Static Routing table and so on.



Firewall
Provide many kinds of Firewall's configurations to prevent from the Internet malicious attack, and may aim at different Port to provide Client filtering, URL Filtering, MAC control and so on for filtering control.



UPNP
Support the UPNP protocol and can display the use of Port mapping.



DDNS
Build-in Dynamic Domain Name Service supporting various services, such as dyndns.org. and so on that can be applied to no fixed Static IP environment.

All of ALLWIN's product lines can support H.323 and SIP protocol simultaneously.





As below application diagram, users can choose the different protocol according to the different call out number making communication via peer to peer, SIP Proxy or H.323 Gatekeeper.

All of ALLWIN's product lines can regsiter up to 4 SIP Proxy or GKs simultaneously.



As below diagram, the area code number of 020 will make redundancy according to the orders of 2>3>1 by 3 SIP server.

Users can review every kind of information below through Web GUI of ALLWIN's VoIP devices.

1) The connecting route, Caller ID, Time, Call out number, off-line reason and so on for every call.



2) Enable and disable status with reasons for registering to every server.



3) Information of Calling package statistics in each line (port).



4) Status for connecting to multiple Auto Provision Server.

5) Execute ping test from CPE for remote internet connecting quality.

The application is quite easy and flexible that users can configure over 100 sets of Call Out and Call In routing rules, besides setting the number length according to different area code, but also can increase or decrease the numbers, choose different route, transfer and protocol, route the call via peer to peer or Proxy Server.

In order to manage many kinds of VoIP devices efficiently, all of ALLWIN's products can be maintained by the specific Auto Provision Server.
The management is to store the devices' configuration and the latest Firmware on the central Provision Server, the remote devices can reach these information from Provision Server regularly or when the devices turn on.
Therefore the provision server can make the central management and solve the problem efficiently if it cannot access the internal IP of remote devices.



GW will synchronize to Provision Server for confirming firmware version when it restarts every time,
also check if there is any newest version or configuration can be downloaded every 60 minutes (user can define the period of synchronization) . Synchronization will be executed at night time even there is no newest data from Provision Server to assure the data is all correct.

Users can configure the call forward of always/on busy/no answer via ALLWIN's VoIP devices, all of the above functions can be configured by all calls are forwarded to the same receiver or assigned different receiver with different line.
