CommPortal Audio Files

Jump to navigation Jump to search

If your CTS phone system utilizes premium voicemail or auto attendants, you will have recordings that need to be created. You have the option to record these items over the phone, directly into the system, but you are also offered the option to upload a file via the CommPortal. In order to be accepted by the system, your uploaded file must be in the correct format.

Record Over the Phone

You will have been given instructions from your VoIP Specialist that included the login information. You will dial into the voicemail system and use the PIN provided. The navigation in the TUI will depend on which kind of thing you are recording. Follow the prompts to record what you need to record.

Upload a File

The system tells you what format the file needs to be in order to upload it.

Valid formats are G711 WAV (8-bit, ulaw / alaw, mono, 8kHz), 16-bit PCM WAV (16-bit, PCM, mono, 16kHz). Announcements must be at most 120 seconds long.

Even knowing these specifications, it is sometimes difficult to get everything set correctly for your audio file. In our experience, it has been easier to successfully create the file with the second option: 16-bit, PCM, mono, 16kHz.

If you attempt to upload a file that does not fit the specifications, it will give you the following alert:

The file uploaded failed, either because it is corrupt or an invalid format. Supported codecs are: G7111 WAV (8-bit, ulaw / alaw, mono, 8kHz), 16-bit, PCM, mono, 16kHz).

Export Example

We have successfully created and edited audio files using Adobe Audition. Here are the settings that were utilized to ensure a successful upload.

  • Sample Type:
    • Sample Rate: 16000 Hz
    • Channels: Mono
    • Bit Depth: 16 bits
  • Format Settings:
    • Format: Waveform Audio
