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.
