CHAPTER37 Advanced SBC Features
Mediant 800 Gateway & E-SBC | User's Manual
■ Configuring an IP Profile (namely, the 'Extension Coders Group' parameter) and IP Group
(namely, the 'IP Profile' parameter) for the media source
■ Designating the media source IP Group as the external media source (in the External Media
Source table, as described above)
■ Configuring IP Profiles (namely, the 'Reliable Held Tone Source' and 'Play Held Tone'
parameters) and IP Groups for the users
However, specific configuration may differ based on your implementation of this MoH feature. For
example, you may implement this feature in one of the following architectures:
■ A company with an on-site external media source for playing all MoH to branch users.
■ A company with an on-site external media source that only plays MoH to branch users when
connectivity with the remote media source is down
A configuration example of an on-site external media source that is always used to play MoH to its
branch users is shown below and subsequently described.
1. Open the Coder Groups table (see Configuring Coder Groups on page403), and then configure
a Coders Group (e.g., AudioCodersGroups_0) with the coder(s) to use for communication
between the device and the media source.
2. Open the IP Profiles table (see Configuring IP Profiles on page414), and then configure two IP
Profiles:
● External Media Source:
◆ 'Extension Coders Group': Assign the Coders Group configured in Step 1 (above).
● Branch Users:
◆ 'Reliable Held Tone Source': No
◆ ' Play Held Tone': External
3. Open the IP Groups table (see Configuring IP Groups on page361), and then configure two IP
Groups:
● External Media Source:
◆ 'IP Profile': Assign the IP Profile configured for the external media source in Step 2
(above)
● Branch Users:
◆ 'IP Profile': Assign the IP Profile configured for the branch users in Step 2 (above)
4. Open the External Media Source table (see the beginning of this section), and then configure an
External Media Source entity and associate it with the IP Group that you configured for the
external media source in Step 3 (above).
