3.3.2.11  Enabling One-Stage Dialing 
One-stage dialing is when the gateway receives an IP-to-Tel call, off-hooks the PBX line 
connected to the PBX / PSTN telephone, and then immediately dials the destination telephone 
number. In other words, the OCS client (i.e., IP caller) doesn't dial the PSTN number upon 
hearing a dial tone.
