Configuring Remote Media Subnets

Remote Media Subnets define destination subnets for media (RTP/SRTP) traffic on a
specific Media Realm. Each Remote Media Subnet can be assigned different call quality
(Quality of Experience Profile) and bandwidth utilization (Bandwidth Profile) profiles. These
profiles are configured in ''Configuring Quality of Experience Profiles'' on page
''Configuring Bandwidth Profiles'' on page 244, respectively. Thus, you can apply these
profiles to remote media subnets instead of Media Realms or IP Groups. You can configure
up to five Remote Media Subnets per Media Realm.
The figure below illustrates an example for implementing Remote Media Subnets. IP Group
#2 represents a SIP Trunk which routes international (USA and India) and local calls. As
international calls are typically more prone to higher delay than local calls, different Quality
of Experience Profiles are assigned to them. This is done by creating Remote Media
Subnets for each of these call destinations and assigning each Remote Media Subnet a
different Quality of Experience Profile. A Quality of Experience Profile that defines a packet
delay threshold is assigned to the international calls, which if crossed, a different IP Profile
is used that defines higher traffic priority to voice over other traffic. In addition, IP Group #2
has a 10-Mbps bandwidth threshold and a "tighter" bandwidth limitation (e.g., 1 Mbps) is
allocated to local calls. If this limit is exceeded, the device rejects new calls to this Remote
Media Subnet.
The following procedure describes how to configure Remote Media Subnets in the Web
interface. You can also configure Remote Media Subnets using the table ini file parameter,
RemoteMediaSubnet
remotemediasubnet.

To configure a Remote Media Subnet:
1. Open the Media Realm Table page (Configuration tab > VoIP menu > VoIP Network
> Media Realm Configuration).
2. Select the Media Realm index row for which you want to add Remote Media Subnets,
and then click the Remote Media Subnet link located below the table; the Remote
Media Subnet table appears.
