20.1.1 Configuring the Channel Select Method
Once you have enabled the PSTN trunk and FXS ports, and assigned them to Trunk
Groups, you need to configure the method for which IP-to-Tel calls are assigned to
channels within each Trunk Group.

To configure the channel select method for each Trunk Group:
1. Open the Trunk Group Settings page ( Configuration tab > VoIP menu > GW and IP
to IP > Trunk Group > Trunk Group Settings ).
Figure 20-2: Trunk Group Setting Page
2. For the FXS ports (i.e., Trunk Group #1), from the ‘Channel Select Mode’ drop-down
list, select By Dest Phone Number. This setting sends the call to a specific FXS user
according to the called (destination) number.
3. For the PSTN trunk (i.e., Trunk Group #2), from the ‘Channel Select Mode’ drop-down
select Cyclic Ascending. This setting sends the call to the next available channel, in
ascending cyclic order.
4. Click Submit to apply your settings.
5. On the toolbar, click Burn to save the changes to the Enhanced gateway flash
memory.
