Figure 108 Recording Screen after Automatic Detection
6 All four Call Progress Tones are saved (as standard A-law PCM at 8000 bits per sample)
in the same directory as the CPTWizard.exe file is located, with the following names:
cpt_recorded_dialtone.pcm
cpt_recorded_busytone.pcm
cpt_recorded_ringtone.pcm
cpt_recorded_invalidtone.pcm
If the gateway is configured correctly (with a Call Progress Tones dat file loaded to the
gateway), all four Call Progress Tones are detected by the gateway. By noting whether the
gateway detects the tones or not, you can determine how well the Call Progress Tones dat file
matches your PBX. During the first run of the CPTWizard, it is likely that the gateway does not
detect any tones.
Some tones cannot be detected by the VCX V7111 gateway hardware (such as 3-frequency
tones and complex cadences). CPTWizard is therefore limited to detecting only those tones
that can be detected on the VCX V7111 gateway.
At this stage, you can either press Next to generate a Call Progress Tones ini file and
terminate the wizard, or continue to manual recording mode.
