How many audio formats are permissible for Digital Receptionist custom prompts?

In the context of Digital Receptionist custom prompts in 3CX, there is a specific requirement for audio formats that can be used. The permissible audio format is a single standardized type, which typically ensures that the system maintains compatibility and performance across various devices and environments. This restriction aids in preventing potential issues related to audio quality or playback inconsistencies that could arise from using multiple formats.

While some other systems might allow for multiple audio formats to provide flexibility to users, 3CX has streamlined this requirement to one format. This approach helps simplify the process, ensuring users only need to work within the confines of a single audio specification for their Digital Receptionist prompts, enhancing both ease of use and system reliability.
