1. Introduction
Micronet SP5208 IP PBX Gateway is an innovative VoIP gear that provides 6
FXS ports for extension calling and SIP trunk for inbound/outbound calls via
ITSP/ISP. Users can benefit from VoIP via built-in PBX functionalities, such as
automated attendant, operator, SIP/PSTN trunk, dial plan, etc, that are supported
by the ease-to-use device.
In addition, 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.

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.
