Information
The Cisco EM-HDA-4FXO is an expansion module that can be installed in certain Cisco router models to provide additional FXO (Foreign Exchange Office) ports. FXO ports are used to connect the router to analog telephone lines, allowing the router to make and receive calls over the traditional telephone network. The EM-HDA-4FXO module adds four FXO ports to the router, expanding its capabilities for voice communication.
