A gateway includes a transceiver operable to transmit and receive communications to a fixed communication device; and a processor cooperatively operable with the transceiver. The processor is configured to facilitate establishing an FXS/FXO connection to the fixed communication device; detecting a configuration query received via the transceiver from the fixed communication device, the configuration query indicating a network infrastructure device for which configuration information is requested; obtaining configuration information corresponding to the network infrastructure device; providing a message with the configuration information inserted therein; and transmitting the message to the fixed communication device via the transceiver.
