Cisco TelePresence SX20 Codec
Contents Introduction
xConfiguration SIP PreferredIPSignaling
Define the preferred IP version for signaling (audio, video, data). Only applicable when both Network
IPStack and Conference CallProtocolIPStack are set to Dual, and the network does not have a
mechanism for choosing the preferred IP version. It also determines the priority of the A/AAAA
lookups in DNS, so that the preferred IP version is used for registration.
Requires user role: ADMIN
Value space: <IPv4/IPv6>
IPv4: The preferred IP version for signaling is IPv4.
IPv6: The preferred IP version for signaling is IPv6.
Example: xConfiguration SIP PreferredIPSignaling: IPv4
xConfiguration SIP OCSP Mode
Not applicable in this version.
xConfiguration SIP OCSP DefaultResponder
Not applicable in this version.
xConfiguration SIP Profile [1..1] 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
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.
Example: xConfiguration SIP Profile 1 Ice Mode: Auto

xCommand
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
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.
Example: xConfiguration SIP Profile 1 Ice DefaultCandidate: Host
Set the discover mode to enable/disable the application to search for available Turn servers in DNS.
Before making calls, the system will test if port allocation is possible.
Requires user role: ADMIN
Value space: <Off/On>
Off: Set to Off to disable discovery mode.
On: When set to On, the system will search for available Turn servers in DNS, and before making
calls the system will test if port allocation is possible.
Example: xConfiguration SIP Profile Turn DiscoverMode: On
Not applicable in this version.
DropRflx will make the endpoint force media through the Turn relay, unless the remote endpoint is
on the same network.
Requires user role: ADMIN
Value space: <Off/On>
Off: Disable DropRflx.
On: The system will force media through the Turn relay when the remote endpoint is on another
network.
Example: xConfiguration SIP Profile Turn DropRflx: Off
