SmartNode IpChannelBank 24 FXS VoIP GW-Router, 2x10/100bTX, UI Power

Patton SN4424/JS/UI - Gateway-Router 24 FXS Ports

The Patton SN4400 SN4416/JS/UI VoIP Gateway supports key industry-standard VoIP signaling protocols such as SIP, H.323, and T.38 Fax Relay—plus fax-bypass and modem-bypass. This ensures interoperability with the leading soft switches and VoIP services. Built-in Quality of Service (QoS) features include voice prioritization and traffic management via configurable service-policy profiles.

Patton’s advanced DownStreamQoS ensures clear, uninterrupted voice—even over best-effort networks such as the Internet. Packet classification using 802.1p, TOS, and DiffServ makes integration with existing managed QoS networks easy.


Create custom security profiles for a comprehensive security environment. IPsec in the SN4400 Series delivers data integrity, authentication, anti-replay and data confidentiality. Firewall capabilities include Access Control Lists (ACLs), IP-address and port filtering, protection against Denial of Service (DoS) attacks, and use of second Ethernet port as DMZ.

Offering easy setup, reliable operation, and third-party interoperability on a proven platform, the SN4400 Series Patton gateway sits at the core of cost-effective business solutions. The investment protection you need for the future is here today.
