Overview

VoiceFinder AP2120N VoIP Switching Gateway is a next generation IP telephony system offering the merits of existing PSTN switch based on the merits of VoIP telephony. It supports maximum 16 NGN service analog ports for enterprises, public offices and SMB (Small Medium Business). It can be installed at the MDF of apartment complexes offering VoIP telephony service to multi-number of individual customers.

Adopting the merits of PSTN Switch and VoIP Gateway

VoiceFinder AP2120N offers the centralized management feature of VoIP gateway and it effectively deals with complex numbering plan of existing PSTN Switch. It overcomes the distance barrels between the subscriber and the VoIP gateway. So the service providers can easily introduce VoIP telephone service without changing the existing infrastructure. Also, it supports caller ID, various ringing, and surge protection of over 4KV and noise immunity of ADSL/ VDSL. AP2120N is ideal for the service providers trying to adopt competitive IP based telephone system without existing system change.

Deploy "Next generation VoIP telephony solution" on current subscriber environment

Until now, introducing IP network such as broadband Internet should be ahead of introducing VoIP telephone service. So at ordinary houses or small enterprises without network managers, adopting VoIP telephone service is not simple, especially in case of system malfunction. AP2120N is a perfect solution overcoming these shortcomings. It is installed at the telecommunication closet or central offices, so the users can subscribe VoIP service without subscribing broadband Internet service such as ADSL/VDSL, cable modem, etc. Also, it supports number of individual users, so the service providers can reduce the maintenance expenses which significantly reducing the service charge.

Distributed IP Telephony network solution

AP2120N VoIP Switching gateway can easily form telephony service network by connecting number of Switching Gateways. So it is a perfect solution to establish distributed IP telephony network.

Supports various network service such as NAT/PAT

VoiceFinder AP2120N VoIP Switching Gateway offers cutting-edge voice compression algorithm along with AddPac's advanced QoS algorithm realizing ultimate voice quality even on low-speed Internet line as well as high-speed Internet. It supports not only reliable dedicated lines but also fixed and dynamic IIP environment of ADSL and Cable model. Also, it offers Static, RIP v1/2, OSPF v2 routing and various network applications such as NAT/PAT. It realized the best price vs. performance ratio on the high speed Internet access environment.
