3.6.11
Interactive Connectivity Establishment (ICE)
ICE arguments in the SDP are sent to negotiate media with the purpose of improving the avail-
ability of the phone to establish a media connection (audio and video) from a peer device. For
ICE to provide this improvement both peers must support ICE.
ICE works by adding to the SDP several candidate addresses by which the peer device may
contact the phone.
3.6.11.1
General
•
Enabled
: Lets the phone include ICE attributes in an SDP offer and provide ICE attributes
in an SDP answer to an SDP offer that included ICE attributes for subsequent calls.
•
Update SDP allowed
: Indicates that the phone will generate an updated SDP offer/answer
as required by the ICE standard.
•
TURN IP mapping
: The TURN server will provide an address mapping between IPv4 and
IPv6 peer endpoints. In other case (not activated) only endpoints supporting the required
IP family may be addressed.
