Quick Guide 5. Configure Device
Version 7.2 31 AudioCodes Mediant Gateway
5.5.2 Configure Trunk Group Parameters
This step shows how to configure the device's channels, which includes assigning them to
Trunk Groups. A Trunk Group is a logical group of physical trunks and channels. A Trunk
Group can include multiple trunks and ranges of channels. To enable and activate the
device's channels, Trunk Groups must be configured. Channels not configured in this table
are disabled. After configuring Trunk Groups, use them to route incoming IP calls to the Tel
side, represented by a specific Trunk Group (ID). You can also use Trunk Groups for
routing Tel calls to the IP side.
To configure the PRI PSTN interface:
1. Open the Trunk Group table (Setup menu > Signaling & Media tab > Gateway folder
> Trunks & Groups > Trunk Groups).
Figure 5-18: Configuring PRI Trunk Group Table
2. Configure each Trunk Group as required. If more than one PRI port is available, on
line 1 of the table above, set 'To Trunk' to the last PRI port (2).
5.5.3 Configure Inbound IP Routing
This section shows configuring Mediant PRI Gateway Inbound (IP-to-Tel) Routing. When
having more than one TDM interface, you can choose to route calls based on incoming IP
SIP call message to a specific TDM port i.e., Trunk Group.
To configure IP-to-Tel or Inbound IP Routing Rules:
1. Open the IP-to-Tel Routing table (Setup menu > Signaling & Media tab > Gateway
folder > Routing > IP > Tel Routing).
Figure 5-19: Configuring Inbound IP Routing Rules
2. Configure a rule for all incoming IP calls, route them to Trunk Group ID 1 (connected
to the PBX).
3. Click Apply.
