1. Introduction

1.1 VoIP Gateway

Micronet SP5008A / SP5018A / SP5058A are high-capacity SIP Gateway Series that

provides 8 FXS / 4 FXS + 4 FXO / 8 FXO ports, and suit to build an IP-based

communication platform with other VoIP devices. They meet enterprise’s requirement for

functionality (VoIP) upgrade and larger scale implementation by interoperating with legacy

PABX and IP PBX/Soft-switch.

To connect with legacy PABX, SP5018A supports PABX Mode for PSTN backup.

When network or power fails, PSTN lines (FXO) bypass to FXS ports and users still can

make/receive calls via PSTN lines.

SP5008A includes some wonderful PABX features for small business. They help

operate users on various VoIP applications, such as extension calling among 8 FXS ports,

inbound/outbound calls via SIP trunk, DID (direct line), DOD, prefix routing, operator

attendant, etc. Users can easily benefit from the ease-to-use device.

SP5208 supports 2 FXO ports to connect with PSTN lines which are subscribed for

company’s representative telephone number. By just connecting FXO ports, users can

make/receive calls via PSTN lines with default configuration. Company with IP-based

platform still can receive daily phone calls from PSTN or GSM, if the direct calling with

PSTN number to VoIP network is not supported by ITSP/ISP. SP5208 also provides PSTN

backup by FXO connections, even if power or network fails. With the smart designs,

SP5208 is a perfect VoIP solution to small business customers.
