Note:
The  billing framework distinguishes between two primary categories: non-conversational and conversational.

The conversational category includes CONVERSATIONAL and CONVERSATIONAL_LEGACY types. Values BASIC_MESSAGE, SINGLE_MESSAGE and CONVERSATIONAL_LEGACY are deprecated and will be removed in a future version.
- CONVERSATIONAL: Designed for longer, more complex sessions where the user and brand exchange a series of messages.
- NON_CONVERSATIONAL: Represents a non-conversational billing category, which replaces the legacy SINGLE_MESSAGE and BASIC_MESSAGE categories. This is for agents that primarily engage in one-way (A2P) communication.
- BASIC_MESSAGE: Billing model is similar to SMS. Deprecated value, use NON_CONVERSATIONAL instead.
- CONVERSATIONAL_LEGACY: Legacy category to support the billing configuration of existing agents.  Deprecated value, use CONVERSATIONAL instead.
