The Voice AI system currently cannot map multiple contacts to the same phone number, which creates awkward interactions when calls originate from shared or office numbers. This is a common scenario for organizations with many facilities, such as nursing homes, where outgoing calls often use a default number. The lack of support leads to misidentification of callers and reduces the fluidity of voice interactions. The requested feature would allow the system to recognize and correctly handle shared numbers, improving accuracy and user experience during calls.
