Cisco TelePresence SX10 Quick Set
Introduction

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 device will be sent to
the Default Candidate as defined in this setting.
Requires user role: ADMIN
Default value: Host
Value space: Host/Rflx/Relay
Host: Send media to the device's private IP address.
Rflx: Send media to the device's public IP address, as seen by the TURN server.
Relay: Send media to the IP address and port allocated on the TURN server.

SIP Ice Mode

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

SIP Line

When registered to a Cisco Unified Communications Manager (CUCM) the device may be
part of a shared line. This means that several devices share the same directory number. The
different devices sharing the same number receive status from the other appearances on
the line as defined in RFC 4235.
Note that shared lines are set up by CUCM, not by the device. Therefore do not change this
setting manually; CUCM pushes this information to the device when required.
Requires user role: ADMIN
Default value: Private
Value space: Private/Shared
Shared: The device is part of a shared line and is therefore sharing its directory number
with other devices.
Private: This device is not part of a shared line.

SIP ListenPort

Turn on or off the listening for incoming connections on the SIP TCP/UDP ports. If turned
off, the device will only be reachable through a SIP Proxy (CUCM or VCS). As a security
measure, SIP ListenPort should be Off when the device is registered to a SIP Proxy.
Requires user role: ADMIN
Default value: On
Value space: Auto/Off/On
Auto: Listening for incoming connections on the SIP TCP/UDP ports is automatically
turned off if the device is registered to a SIP Proxy; otherwise it is turned on.
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.

SIP Mailbox

When registered to a Cisco Unified Communications Manager (CUCM) you may be offered
the option of having a private voice mailbox.
Requires user role: ADMIN
Default value: ""
Value space: String (0, 255)
A valid number or address. Leave the string empty if you do not have a voice mailbox.
