First Claim
Patent Images
1. A method, comprising:
- configuring a packet engine in a bearer stream between a first telephone device and a second telephone device;
determining, by the packet engine, via a buffer and an inter-digit timer utilized by the packet engine, a start and a stop of patterns associated with dual-tone multi-frequency digits in order to differentiate a feature invocation digit pattern from the dual-tone multi-frequency digits; and
reporting, by the packet engine, a dual-tone multi-frequency event to the call server in response to determining the start and a stop of patterns associated with the dual-tone multi-frequency digits.

17. A server, comprising:
-
a user space module configured to receive and send commands from and to the Voice over Internet Protocol network; and a kernel module configured to receive a bearer stream comprising Real-time Transport Protocol packets from an IP stack, wherein the kernel module utilizes an inter digit timer to determine a start and a stop of patterns associated with the dual-tone multi-frequency digits in order to differentiate a feature invocation digit pattern from the dual-tone multi-frequency digits; wherein the user space module reports a dual-tone multi-frequency event to the call server in response to determining the start and a stop of patterns associated with the dual-tone multi-frequency digits. - View Dependent Claims (18, 19, 20)

21. A server, comprising:
-
a first module configured to establish a Voice over Internet Protocol call session; and a second module configured to detect digit events within an active Voice over Internet Protocol call session, wherein the second module utilizes a buffer and an inter digit timer to determine a start and a stop of patterns associated with the digit events in order to differentiate a feature invocation digit pattern from the digit events. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
