About Synapse
®
and the Synapse SB67070 SIP
Gateway
Synapse is an IP-based PBX system that integrates seamlessly into an existing Local
Area Network (LAN). A Synapse system can include any or all of the following
devices:
 SB67010 PSTN Gateway
 SB67050 Analog Terminal Adapter (ATA)
 SB67060 T1 Gateway
 SB67030, SB67031, or SB67020 Desksets
 SB67070 SIP Gateway
To deploy Broadvox GO! SIP Trunking service, the Synapse system must include a
SB67070 SIP Gateway. The SB67070 SIP Gateway allows the Synapse system to
make and receive external calls via a SIP Trunk Service Provider.
Currently, one SIP Gateway and four SIP accounts are supported on a single Synapse
system.
SB67070 SIP Gateway Features:
 A LAN 10/100 BaseT Ethernet port connects to the existing Synapse network.
 A four-line LCD display with four hard keys provides status information, such
as the device IP address, and allows basic network configuration and firmware
upgrades.
 Device configuration and system configuration, such as SIP Account
information, through the Web User Interface (WebUI).
 Up to 16 simultaneous voice calls are supported.
 Additional System features, including Direct Inward Dial (DID) and multiple
Auto Attendants.
