Media routing without ICE
When the ICE protocol is used in a call, media links are established directly between the two endpoints in
non-traversal calls, or between Movi and the VCS in traversal calls. As a general rule, non-traversal calls are
defined as calls between two participants that are on the same network and that don’t require interworking.
Note that SIP to H.323 calls require interworking and are therefore traversal calls irrespective of whether the
endpoints are on the same network. For detailed information, see the latest
VCS Administrator Guide
.
Media routing with ICE
ICE dynamically discovers the best possible path for media to travel between call participants.
It’s possible to further improve the routing of media and force it through dedicated links by using the Enable
MNS Mode Provisioning configuration.
Enabling ICE
Media routing using ICE requires a TURN server. VCS Expressway running version X5.2 or later can
function as a TURN server if it has TURN Relay licenses.
To set the necessary configurations on the VCS Expressway:
1.
Go to VCS configuration > Expressway > TURN (Having the TURN server option key is required)
and configure the fields as follows:
TURN services
On
Port
3478
Media port range start
60000
Media port range end
61399
2.
Go to VCS configuration > Authentication > Devices > Configuration and set the Database type
to LocalDatabase.
3.
Go to VCS configuration > Authentication > Devices > Local database and create a username
and password. The username and password are necessary to allow for use of TURN Relay licenses.
The Movi client is provisioned with the username and password as described below.
To enable ICE on the Movi client, four Provisioning configurations must be set:
1.
Set Enable ICE to On.
2.
Set TurnAuthPassword to the password created in step 3 of the VCS configurations.
3.
Set TurnAuthUsername to the username created in step 3 of the VCS configurations.
4.
Set TurnServer to the address of the server through which media is relayed in an “ICE call”. Typically,
the address of the VCS Expressway.
Note: The ICE Provisioning configurations are not available by default. See the
Uploading Movi 4.0
Provisioning options to the TMS
section for more information.
