Set Prompts for Failed Calls

A user may fail to make outbound calls due to many reasons, such as the trunk is busy, no trunk available, or invalid number. You can set different prompts to inform the user why the call fails.

1. Go to Settings > PBX > Voice Prompts > Prompt Preference.
2. Set the prompts for different type of failed calls.
   
   • Invalid Phone Number Prompt: The PBX will play the prompt when the dialed number is invalid.
   • Busy Line Prompt: The PBX will play the prompt when the trunk used is busy.
   • Dial Failure Prompt: The PBX will play the prompt if no trunk is available to call out.
