Coral Sentinel Pro
The Coral Sentinel Pro is a Session Border Control (SBC) unit that enables the
connection of remote IP phones located behind NAT (Network Address Translation)
servers or firewalls. Its main purpose is to transfer signalling and RTP traffic through
the firewall or NAT server to the relevant endpoints in the LAN network.
The Sentinel Pro provides the following features:
Enables incoming traffic to be routed through a firewall, without the need to
open up a permanent channel to transmit and receive calls
Enables MGCP endpoints that are remotely located behind a NAT server to
transverse the server
Establishes local RTP sessions between remote MGCP endpoints located
behind the same NAT server, thereby freeing up Sentinel RTP resources
Enables NAT traversal and firewall penetration for real-time fax-based sessions
utilizing the T.38 protocol
Enables NAT traversal and firewall penetration for IP phones and softphones
with different media types such as Audio (high quality
1
G.722) and
Video (H.263)
The Sentinel Pro can operate with UCx, Coral FlexiCom, Coral IPx, and Aeonix
Systems.
For SIP endpoints use a 3rd party SBC.
