How CNAM Works in Groups
-
Individual Lines: Each phone line (or number) within the group will have its own CNAM information associated with it. When calls are made from these lines, the CNAM data specific to that line is transmitted to the receiving party's phone.
-
Exceptions: In some cases, businesses or organizations may use centralized systems or services where CNAM information can be managed centrally. This could involve configuring CNAM settings for all lines within a group through a telecommunications provider or PBX (Private Branch Exchange) system.
Practical Considerations
-
Configuration: To ensure consistent CNAM display across all phones in a group, businesses may need to configure CNAM settings with their telecommunications provider or through their phone system (e.g., PBX or VoIP service).
-
Limitations: CNAM propagation is subject to telecommunications standards and practices, which may vary. Not all carriers or systems support the same level of CNAM management or synchronization across group phones.
