    摘要： In a wireless communication system, when receiving a START DTMF message with an ITR indicator from a transmitting device, a network is configured to send a START DTMF ACK message to the transmitting device. After adjusting its settings and entering a text receiving mode, the transmitting device is configured to send a CONFIRM START DTMF TXT message to the network. The network is configured to send keypad information associated with the number of a receiving device to the receiving device. The receiving device is configured to send the corresponding text message to the network, which then forwards the text message to the transmitting device.

    摘要： There is provided a method of correlating a telephone call between a first party and a second party with information that is to be used in a third party service implemented in relation to the telephone call. The method comprises routing telephone calls involving the first party via a third party service system that implements the third party service. The method further comprises, at a communication management system of the first party, determining call identification data for the telephone call and session data associated with a session of the third party service to be implemented in relation to the telephone call, and sending the call identification data and the session data to the third party service system; and, at the third party service system, receiving the call identification data and the session data from the communication management system, using the received call identification data to identify the telephone call, using the received session data to determine the information that is be used in the third party service, and correlating the information with the identified telephone call.

    摘要： A T2P (TDM to packet) delay buffer is provided. The delay buffer can prevent double digit detections caused by in-band DTMF leak when out-of-band DTMF is used. The T2P delay buffer is initialized with an audio pattern that represents silence in a configurable amount of delay. When a DTMF digit is detected, the system can stop taking the voice payload from the T2P delay buffer and start injecting RFC4733 RTP packets into the RTP stream at a pre-configured rate. The RFC4733 DTMF RTP packets continue to be injected into the RTP stream until the DTMF digit stops. Once the end of the DTMF digit is detected, the content of the T2P delay buffer can be discarded and the T2P delay buffer is reinitialized with an audio pattern that represents silence in a configurable amount of delay. After the T2P delay buffer is reinitialized, the voice packetization can be continued.

    摘要： Various implementations include systems and methods for unlocking a door to a building on behalf of a tenant of the building that addresses the shortcomings of legacy telephone entry systems and allows for more efficient and safer management of building entry requests from third parties. In some implementations, the system taps into the legacy telephone entry systems to communicate with third parties seeking entry into the building. In some implementations, the system communicates with third party computing devices (e.g., stationary or mobile devices) to process entry requests. And, in some implementations, the system communicates entry preferences (or parameters) associated with a tenant with a door lock system to allow for entry during certain time windows or under certain conditions.
