Application for SmartNode 4140 VoIP Gateway
The SmartNode 4140 VoIP Gateway, equipped with 1 Ethernet port, acts as a VoIP Gateway connecting
POTS equipment which cannot easily be replaced by an IP-ready device (such as alarm systems, fax machines,
modems, PoS terminals, etc.) into an All-IP environment. In addition SN4140 models with FXO interfaces
serve use-cases where survivability is desired (see
).
Additionally, /2ETH models have 2 Ethernet ports, which enable them to be upgraded to enterprise session
border controllers (eSBCs) after purchasing a software license.
The major functions of the SmartNode 4140 VoIP Gateway are:
•
Network quality assessment and monitoring (optional PacketSmart
1
)
•
QoS (packet tagging)
•
Number normalization and mapping
•
Fallback and survivability call routing to alternate SIP provider/IP-PBX
•
Fax, modem, PoS integration and VoIP conversion
•
Legacy telephone to VoIP conversion
•
PSTN line integration for IP based on premise telephony setups
