Voice over IP support
It has always been difficult to deploy IP telephony
in firewall-protected networks since VoIP protocols
were not designed to easily traverse the firewall.
Kerio WinRoute Firewalls supports various VoIP-based
hardware or software such as Cisco IP Phone 7960,
IP SoftPhone, CallManager, Gatekeeper, SIP Proxy
Server, Interactive Voice Response, Cisco Unity
Voice Mail, etc.
H.323 and SIP
Kerio's protocol inspection modules help the firewall
correctly handle VoIP phone and video communication.
Kerio WinRoute Firewall allows all VoIP devices
using either H.323 or SIP protocol to be used
in the protected network and therefore eliminates
the need to publicly expose the VoIP infrastructure
to the Internet.
Cisco SCCP
If a company wants to take advantage of VoIP devices
in Cisco AVVID environment, Cisco's Skinny Client
Control Protocol (SCCP) is used for establishing
communication between an IP Phone and Cisco CallManager.
The firewall of course needs to recognize it and
understand the information passed within these
signalling messages.
Kerio WinRoute Firewall automatically detects
SCCP protocol and perfoms NAT for address translation
between the IP phone and Cisco CallManager. Since
Kerio WinRoute Firewall performs dynamic IP address
translation, an administrator does not need to
manually configure an IP address within NAT for
each IP phone.
UPnP support
Universal Plug and Play (UPnP) in Windows enables
applications to communicate without additional
settings at the firewall. Kerio WinRoute Firewall
integrates UPnP technology so that compliant applications
such as MSN Messenger can run instantly without
hassle. |
