Patton ESBR, 4 SIP Sessions (SIP back-to-back calls), upgradeable to max 32 SIP Sessions (see SNSW-4B), 5x Ethernet, no VoIP Channels, External UI Power (SN5200/4B/EUI)
The SN5200 enables Universal SIP Trunking and provides a single
Integrated Access Device with features like IP Routing, Redundancy,
Security and a SIP registrar for survivability. The Enterprise can use a single conduit for both its voice and data traffic thus making the most cost efficient use of its resources. By using two SN5200 with VRRP enabled an
Enterprise could connect to two ITSP and provide for failover incase the primary SIP provider trunk has a problem.
