VoiceFinderAP1900S is a secure VoIP gateway which support up to 16-ports analog voice interface and one(1)-port digital E1/T1 voice module. AP1900S supports optimum level of call scenario when interworking with conventional PBX. Also, it is embedded with encrypt processing function such as AES, SEED and custom encryption algorithm(ARIA, etc) to support SRTP (Secure RTP), TLS 1.x VoIP communication.
Concurrent Support of 16 Port Analog Interface and Digital Interface
VoIP gateway suggests a new model as a main communication solution by integrating with IP-PBX. An obvious reason of selecting the right product is for better VoIP communication. AddPac AP1900S is a midrange level VoIP gateway which support analog interface based 16 ports and one(1) port digital E1/T1 interface. It can be used as both media gateway which interwork with IP-PBX and substitution of small/medium analog PBX under general enterprise environment, public office environment, and local government environment. Adopting AP1900S with MUX or leased line allows having optimum level of VoIP communication. AP1900S is designed to support a high performance service as a media gateway. Network interface at front supports several status check LED and line operating status LED, so that it enables to see the device status at a glance. Two 10/100Mbps fast Ethernet port and RS232C console interface can be the basis of various network services such as LAN-to-LAN routing service, bridge service, and NAT/PAT service.
High Satisfaction of Voice Quality and Supplementary Service
AddPac VoIP gateway series is well recognized throughout the world in terms of its stability and performance. We have been accumulated our experiences and know-how in enterprise market as well as in telecommunication market. AP1900S will give you full satisfaction by providing various services to meet the needs of customer demand. It supports concurrent triple VoIP call control protocol such as H323. SIP, MGCP and QoS (Quality of Service) for superb communication quality.
Ultimate VoIP Security Solution without a Falling Off in Quality
VoIP phone is no longer in safety zone which is usually safer than PSTN phone due to an interception with VoIP capture packet device. Adopting separate VPN (Virtual Private Network) device to promote VoIP communication safety can be one way, yet this is not an alternative solution. VPN based VoIP has several problems. First, VPN based VoIP security requires an entire network traffic encryption so that it may cause a decrease in voice quality. On the other hand, built-in encrypted functionSecure VoiceFinder AP1900S can avoid the quality of phone conversation due to network delay since it is able to communicate with encrypted VoIP voice data. VPN VoIP network requires a separategatekeeper for VPN internal network, so it has a disadvantage in terms of introduction cost compare to built-in encrypted function Secure VoiceFinder AP1900S. On top of that, cost of introduction will increase significantly if adopting separate VPN device.
VoiceFinderAP1900S is an alternative VoIP security solution to solve the problem. It does not require a separate VPN device and may able to use public SIP server or H.323 gatekeeper so it has the advantage of stability and introduction cost.
VoIP Security Application Possibility in Part of Section
With introduction of Secure VoIP gateway AP1900S, VoIP security is no longer necessary. If user needs to talk with VoIP gateway which is connected with VPN device, other party also requires VPN device as well. This may cause dissipation of budget due to the part of VoIP network section security. Secure VoiceFinder AP1900S is a right solution for encrypted communication in specific area and VoIP communication is possible in the rest of area. AP1900S can communicate in real time only if other VoIP gateway supports encryption standard otherwise, it supports general VoIP communication system. Secure VoiceFinder AP1900S is the answer to maintain the VoIP security as well as to provide general VoIP communication. AP1900S secure VoIP gateway allows to communicate with encrypted code in specific site and general VoIP communication in rest of area. AP1900S supports to communicate in real time if other party’s VoIP gateway supports encryption and support general VoIP communication in case of general VoIP gateway.
Supports High Performance Voice Encryption/Decode based on Security Processor
Secure VoiceFinder AP1900S is a realistic solution for customer in terms of VoIP telecommunication security. AP1900S secure VoIP gateway supports a high quality telecommunication as well as an excellent VoIP security based on SRTP protocol. With introduction of AP1900S secure VoIP gateway, separate VoIP security is not necessary in most enterprise and public office. With QoS management function, it supports state-of-the-art technology voice compressed algorithm and QoS management function for superb voice communication quality as well as saving operation cost/introduction cost. Especially, processing delay rarely occurs due to high speed VoIP voice encryption with AddPac security processor.
| Category | VPN + VoIP Gateway Security | AP1900S Secure VoIP Gateway Security |
| Encrypted Data | Entire Network Data (Possible Delay) | Only VoIP Voice Data |
| Secured Area | Apply in general | Only selected areas, (Ordinary VoIP calls are possible for other areas) |
| GateKeeper Requirement | Internal GK is mandatory | Not essential. Able to utilize external public GK |
| Origin of the encryption process | VPN Device | Secure VoIP Gateway |
| Center Line Error | Failure on the entire network | Failure on calls connected to main office |
| Network Configuration Advantage | Low (In a large-scale VoIP network, it cannot emerged into mesh structure.) | High (Can be easily formed as mesh type and be expanded easily) |
| Investment | High (VPN device and additional GK requires) | Low |
