The address of the server media is relayed through in an “ICE call”, typically the
address of the Cisco VCS Expressway
Note:
The ICE Provisioning configurations are not available by default. See the
Provisioning
section for
more information.
Configuring Movi's TURN port
TURN port configuration should be controlled through DNS. Movi will do an SRV lookup for the TURN ip,
pri, weight, and port. As TURN runs over UDP, the lookup will be for
_turn._udp.<domain>
. If no
SRV record for TURN is found, Movi will perform an A record lookup (IPv4) or an AAAA lookup (IPv6),
but will default to port 3478.
If the port needs to be provisioned, you can append it to the IP address in the
TurnServer
field, for
example
192.0.2.0:3478.
