1. Introduction

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.

In addition, 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.
