Introduction

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
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 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
Value space: Host/Rflx/Relay
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.

SIP Ice OfferTcpCandidates

Define whether or not the video system supports sending and receiving media over TCP
connections.
Requires user role: ADMIN
Default value: Off
Value space: Off/On
Off: The video system does not allow media over TCP connections.
On: The video system allows media over TCP connections.

SIP Line

When registered to a Cisco Unified Communications Manager (CUCM) the endpoint 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 endpoint. Therefore do not change
this setting manually; CUCM pushes this information to the endpoint when required.
Requires user role: ADMIN
Default value: Private
Value space: Private/Shared
Shared: The system is part of a shared line and is therefore sharing its directory number
with other devices.
Private: This system is not part of a shared line (default).

SIP ListenPort

Turn on or off the listening for incoming connections on the SIP TCP/UDP ports. If turned
off, the endpoint will only be reachable through the SIP registrar (CUCM or VCS). It is
recommended to leave this setting at its default value.
Requires user role: ADMIN
Default value: On
Value space: Off/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.
