Abstract:
1. A method comprising: determining that a first telephonic call arriving at a first number is associated with a particular caller based on a call-identification data; determining that a first voicemail message of the first telephonic call is saved in a non-transitory storage medium associated with the first number; associating a forwarded number of the first voicemail message of the first telephonic call with the first number and a call-forwarding history of the first telephonic call; generating an archived view of the first number, the forwarded number, and the call-identification data; presenting the archived view to a user of a medical tracking system through a web interface; archiving the first telephonic call associated with the particular caller, based on the call-identification data; recording the first voicemail message of the first telephonic call; saving the first voicemail message in the non-transitory storage medium associated with the first number; providing a call-tree configuration for retrieval for at least one of the call-identification data, the first voicemail message, and a voicemail retrieval history; generating a dual-tone multi-frequency signaling over a telephone line in a voice-frequency band; utilizing a row tone and a column tone using a sine generator and adding the row tone and the column tone to the sine generator to form a dual-tone multi-frequency signal; controlling a frequency of the dual-tone multi-frequency signal through a keypad; and decoding the dual-tone multi-frequency signal by extracting two tones in the dual-tone multi-frequency signal and determining from their value an intended dual-tone multi-frequency signal digit; extending a call resource accessible through an application programming interface; recording a second telephonic call between an initial caller and a recipient performed through the application programming interface; routing a second voicemail message to an appropriate user; notifying the initial caller of a voicemail message retrieval; monitoring, tracing and auditing the second telephonic call, the second voicemail message, and the voicemail message retrieval; notifying the initial caller of the voicemail message retrieval using alerts to a data processing system; and displaying a message recording history on at least one of a computer user interface and a mobile device; recording the second telephonic call made over at least one of a group comprising a public switched telephone network and a voice over internet protocol network between the plurality of users; recording a short message service communication between the plurality of users; and routing a short message service message to the appropriate user, wherein a sample rate of the dual-tone multi-frequency signal is be set using a global parameter and a frame size.
