  • Patent number: 8559604
    Abstract: Certain embodiments of the present disclosure provide systems and methods for voicemail notification. In one embodiment, a method includes submitting an extension call request to a telephony system, wherein the extension call request identifies a recipient extension. The method also includes receiving a return message from the telephony system in response to the extension call request. The method further includes determining whether the recipient extension is currently associated with the telephony system based on the return message received from the telephony system. In addition, the method includes documenting an association between the recipient extension at the telephony system if the recipient extension is currently associated with the telephony system. The preceding operations may be repeated for additional recipient extensions and/or additional telephony systems to determine associations between one or more recipient extensions and one or more telephony systems.

  • Patent number: 7912189
    Abstract: An improved approach to failover voice messaging services is provided. In one example, a method includes detecting a network communication interruption between a branch office and a main office, provisioning a mailbox of a failover voice messaging system of the branch office, and receiving an incoming call at the branch office. The method also includes routing the incoming call to the mailbox, storing a message associated with the incoming call in the mailbox, and detecting a restored network connection between the branch office and the main office. The method further includes synchronizing the message between the mailbox of the failover voice messaging system of the branch office and a corresponding mailbox of a voice messaging system of the main office in response to the restored network connection. Failover voice messaging systems supporting such features are also provided.

  • Patent number: 7912184
    Abstract: A method and system for testing a Telephony User Interface is disclosed. Voice prompts of the Telephony User Interface are converted into tone prompts that are representative thereof. Each tone prompt can have a predetermined frequency and/or duration, so that it is readily recognizable by a Telephony User Interface tester. Thus, automation of the testing of Telephony User Interface is enhanced.
