
To configure the number of media channels:
1. Open the IP Media Settings page ( Configuration tab > VoIP menu > IP Media > IP
Media Settings ).
Figure 20-6: Defining Required Media Channels
2. In the 'Number of Media Channels' field, enter the required number of media channels
(in the example above, "120" to enable up to 60 IP-to-IP calls).
3. Click Submit .
4. Save the settings to flash memory ("burn") with a device reset (see 'Saving
Configuration' on page
520 ).
20.2.3 Step 3: Define a Trunk Group for the Local PSTN
For incoming and outgoing local PSTN calls with the IP-PBX, you need to define the Trunk
Group ID (#1) for the T1 ISDN trunk connecting the device to the local PSTN. This Trunk
Group is also used for alternative routing to the PSTN if connectivity with the ITSP fails.

To configure the Trunk Group for local PSTN:
1. Open the Trunk Group Table page ( Configuration tab > VoIP menu > GW and IP to
IP > Trunk Group > Trunk Group ).
2. Configure Trunk Group ID #1 (as shown in the figure below):
•
From the 'From Trunk' and 'To Trunk' drop-down lists, select 1 to indicate Trunk 1
for this Trunk Group.
•
In the 'Channels' field, enter the Trunk channels or ports assigned to the Trunk
Group (e.g. 1-31 for E1 and 1-24 for T1).
•
In the 'Phone Number' field, enter any phone number (logical) for this Trunk (e.g.
1000).
•
In the 'Trunk Group ID' field, enter "1" as the ID for this Trunk Group.

3. Configure the Trunk in the Trunk Settings page ( Configuration tab > VoIP menu >
PSTN > Trunk Settings ).
20.2.4 Step 4: Configure the Proxy Sets
The Proxy Sets represent the actual destination (IP address or FQDN) to which the call is
routed. These Proxy Sets are later assigned to IP Groups (see 'Step 5: Configure the IP
Groups' on page
288 ).
This step describes how to configure the following Proxy Sets:
