VoIP Networks without PSTN — Example 3
One Hunt Group (48 Channels Across Two T1s)
This dialing scheme uses one hunt group spanning two T1 lines to make a single 48 channel 
trunk.
Hunt groups are called voice numbering plans in the AVNDS. Voice numbering plans relate 
phone groups and destinations. In this example, the voice daughtercards are using the top 
down hunt method to determine where new calls will be routed.
