Latest Patents
One of her latest patents is titled "On-net direct access to voicemail." This invention involves a device in a provider network that receives a Session Initiation Protocol (SIP) request message from an originating device. The SIP request message includes a general number for a voicemail service that encompasses multiple voicemail systems. The device determines if the originating device is associated with a voice-over-Internet-protocol (VoIP) account and selects a direct access number assigned to a voicemail system servicing that account. The device then forwards the SIP request message to an application server based on the direct access number.
Another notable patent is "Defining third-party voice mail access numbers in view of LATA boundaries." This method includes selecting a voicemail out-dial access number corresponding to a local access transport area (LATA) boundary. The access number is stored on a voicemail system, which provides voicemail out-dial service based on the associated LATA boundary. This innovation allows for toll-free access to the voicemail system for customers from both on-network and off-network endpoints.
