31.13.1.1

One-Stage Dialing

One-stage dialing is when the FXO device receives an IP-to-Tel call, off-hooks the PBX
line connected to the telephone, and then immediately dials the destination telephone
number. In other words, the IP caller doesn't dial the PSTN number upon hearing a dial
tone.
One-stage dialing incorporates the following FXO functionality:

Waiting for Dial Tone: Enables the device to dial the digits to the Tel side only after
detecting a dial tone from the PBX line. The ini file parameter IsWaitForDialTone is
used to configure this operation.

Time to Wait Before Dialing: Defines the time (in msec) between seizing the FXO
line and starting to dial the digits. The ini file parameter WaitForDialTime is used to
configure this operation.
Note: The ini file parameter IsWaitForDialTone must be disabled for this mode.
