Introduction

SIP Ice Mode

ICE (Interactive Connectivity Establishment, RFC 5245) is a NAT traversal solution that the
endpoints can use to discover the optimized media path. Thus the shortest route for audio
and video is always secured between the endpoints. NOTE: ICE is not supported when
registered to CUCM (Cisco Unified Communication Manager).
Requires user role: ADMIN
Default value: Auto
Value space: Auto/Off/On
Auto: When set to Auto, ICE will be enabled if a turn server is provided, otherwise ICE
will be disabled.
Off: Set to Off to disable ICE.
On: Set to On to enable ICE.

SIP Ice DefaultCandidate

This is the default IP address that the endpoint will receive media on until ICE has reached a
conclusion about which media route to use (up to the first 5 seconds of a call.
Requires user role: ADMIN
Default value: Host
Value space: Host/Rflx/Relay
Host: The endpoint will receive media on its own IP address.
Rflx: The endpoint will receive media on its public IP address as seen by the TURN
server.
Relay: The endpoint will receive media on the IP address and port allocated on the TURN
server, and is used as a fallback until ICE has concluded.

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.
