User defined name for this telephone line.

End-Of-Call Detection

Use the end-of-call tone detection from both the hardware and its internal software detection. The default settings usually work well but if you find that calls hang up unexpectedly (during playback or record) or you have good hardware and want to reduce call online times, tick the Enable end-of-call tone detection during playback option.

Enable end-of-call tone detection during playback By default this is off to stop the out-going audio being mistaken for an end-of-call tone by cheaper voice modem circuits. If you have a professional telephony device and are playing long recordings you might try turning this on so that DialDictate will disconnect immediately if the caller hangs up during playback. Otherwise it waits to the end of playback.

Enable software based end-of-call tone detection By default this is on so DialDictate detects the end-of-call tone even when the hardware fails to detect it. This must be on if end-of-call tone detection during playback is off.

Call Detection Timing

Most hardware takes a little time to detect end-of-call tones or DTMF tone presses. The end-of-call or key press will only be reported after it has been recorded. To compensate for this the software rewinds the recording a preset time so that the end of the recording is more exact. Because different hardware has different timing you may need to adjust these for optimal performance.

End-Of-Call Detect Delay (ms). This is the time that the software trims a recording back after the end of call tone is detected. If you find your recordings are chopped off (at the end of a recording) reduce this time. If you find too much of the end-of-call tone is recorded, increase this time. (Note: if you find it is very long make sure you have enabled software end-of-call detection as described above). The default value is 4500.

DTMF Tone Detect Delay (ms). This is the time that the software trims a recording back after a caller presses a key. If you find the recording is chopped off you can reduce this a little. Beware: a too short time can cause unpredictable results if a recording includes the DTMF tone itself because when that recording is replayed the tone will be redetected. The default value is 350ms.

Distinctive Ring Detection

On some phone lines it is possible to have different ring 'sounds' to differentiate between calls of different type (eg. faxes or voice calls) or calls to different numbers (where different numbers are received on one line).

Distinctive Ring is processed using a Distinctive Ring Number. The number is somewhat arbitrary (see below).

Use hardware based distinctive ring

When selected the DRN is a number returned directly from the voice modem or telephony voice board. If the hardware supports distinctive ring detection we recommend that you use it. The problem is that many voice modems and telephony voice boards do not support distinctive ring and in that case you need to use software detection.

Use maximum ring interval - software based ring detection

When this option is selected, the software uses the maximum time between rings to calculate the DRN. If the maximum time is above the set time it will report a DRN of 1. If it is below it will report a DRN of 0.
