摘要:
An enhanced services display message protocol (ESDMP) facilitates display of messages in a compliant analog telephony device (ATD). An exemplary gateway device in a voice over packet (VOP) network can activate enhanced services in a compliant ATD using the ESDMP and includes a controller and first and second interfaces. One of the interfaces can transmit and receive communications over a VOP network. The other interface can transmit and receive voice band message data modulated according to a frequency shift keying (FSK) protocol. The ESDMP can be used to configure the gateway to activate features supported by the ATD, to update call state information and to display feature state information.
摘要:
A method and system that enables IP (Internet Protocol)-like features on a conventional telephone that is connected to a device that handles voice calls on a network, such as a media gateway. The device sends messages concerning acknowledgement of call features, call status, call updates, and diagnostic or informative error information to the caller identification display on the conventional telephone.

摘要:
A fixed communication device includes a transceiver operable to transmit and receive communications to a gateway, and a processor cooperatively operable with the transceiver. The processor is configured to facilitate establishing a foreign exchange office (FXO) connection to the gateway over the transceiver; formatting a message in a multiple data message format (MDMF) message format; and transmitting the message from the transceiver to the gateway using frequency shift keying (FSK) modulation, after the FXO connection is established
