Introduction

xConfiguration SIP Ice Mode

ICE (Interactive Connectivity Establishment, RFC 5245) is a NAT traversal solution that the video
systems can use to discover the optimized media path. Thus the shortest route for audio and
video is always secured between the video systems.
Requires user role: ADMIN
Default value: Auto
USAGE:
xConfiguration SIP Ice Mode: Mode
where
: Auto/Off/On
Mode
Auto: ICE is enabled if a TURN server is provided, otherwise ICE is disabled.
Off: ICE is disabled.
On: ICE is enabled.

xConfiguration SIP Ice DefaultCandidate

The ICE protocol needs some time to reach a conclusion about which media route to use (up to
the first 5 seconds of a call). During this period media for the video system will be sent to the
Default Candidate as defined in this setting.
Requires user role: ADMIN
Default value: Host
USAGE:
xConfiguration SIP Ice DefaultCandidate:
where
: Host/Rflx/Relay
DefaultCandidate
Host: Send media to the video system's private IP address.
Rflx: Send media to the video system's public IP address, as seen by the TURN server.
Relay: Send media to the IP address and port allocated on the TURN server.

xConfiguration SIP ListenPort

the endpoint will only be reachable through the SIP registrar (CUCM or VCS). It is recom-
mended to leave this setting at its default value.
Requires user role: ADMIN
Default value: On
USAGE:
xConfiguration SIP ListenPort:
where
: Off/On
ListenPort
Off: Listening for incoming connections on the SIP TCP/UDP ports is turned off.
On: Listening for incoming connections on the SIP TCP/UDP ports is turned on.
xConfiguration SIP Proxy [1..4] Address
The Proxy Address is the manually configured address for the outbound proxy. It is possible to
use a fully qualified domain name, or an IP address. The default port is 5060 for TCP and UDP
but another one can be provided.
Requires user role: ADMIN
Default value: ""
USAGE:
xConfiguration SIP Proxy n Address: "Address"
where
: Index that identifies the proxy (maximum 4 proxys can be defined). Range: 1..4
n
: String (0, 255)
Address
A valid IPv4 address, IPv6 address or DNS name.
