It supports the state-of-the-art functions which you never have experienced in existing GSM gateway in terms of scalability and environment flexibility. It provides the optimum level of call scenario for radio device interworking through IP-PBX, PTT server and LMR (Land-to-Mobile Radio) gateway in VoIP interface.

GSM and VoIP Gateway Service Both Support

AddPac AP-GS3500PGG is a device that can support both GSM gateway service (Digital E1/T1?GSM or Internet?GSM) and VoIP gateway service (Digital E1/T1?Internet) simultaneously. It also supports SIP, H.323 Multiple VoIP signaling protocol, various voice codec support(G.711, G.726, G.729, G723.1), nine(9) module slots for GSM and VoIP module, one(1) module slot for CPU board, two(2) fast ethernet ports, 1-port RS232C console, and state-of-art technologies and services.

Supports maximum 36 ports of GSM interface

GSM gateway combining IP-PBX(or Conventional PBX) is now suggesting a new model for a main voice communication solution. In order to be a part of advanced VoIP communications naturally in the future, making an excellent choice of choosing GSM gateway is essential. VoiceFinder AP-GS3500PGG is a mid-range GSM gateway providing total 32GSM interface ports + one(1) Digital E1/T1 port. It is suitable for general enterprises, medium and large public offices. It has functions as a GSM gateway which interoperates with IP-PBX or conventional PBX. Especially AP-GS3500PGG provides an optimal solution of VoIP and GSM communications in telephony environments that using telephone lines and PBX to get connect with a head office.

Powerful networking protocols

VoiceFinder AP-GS3500PGG PTT GSM Gateway supports two(1) 10/100 Base-T fast Ethernet Interface ports and provides stabilized leased line environment, ADSL environment, cable modem environment, fixed IP Address, supports all flow IP environment so that it can be selected in accordance with user environments.

Adapt to the Future Environment: Firmware Upgradeable Technology

Designed on programmable high performance RISC Integrated DSP Technology, AP-GS3500PGG is capable of adopting new capabilities and improvement by downloading firmware from website or with its auto-upgrade option as the customers' needs grow. Moreover, operators can download the latest protocol or service improvements as well as update firmware by checking the version and activating the auto-upgrade via AP-NMS (Network Management System) or AP-VPMS(VoIP Plug &Play Management System) system of AddPac Technologies.
