| 20100098236 | CALL FORWARDING TO VOICE MAIL SYSTEMS BASED ON REDIRECTING NUMBER - A method is disclosed that includes receiving a forwarded call. The forwarded call corresponds to a call forwarded from a first redirecting telephone device to a second redirecting telephone device. The forwarded call has an associated data message that includes a calling number of an originating telephone device and a first redirecting number of the first redirecting telephone device. The method also includes selecting a destination voice mailbox. The destination voice mailbox is selected from a plurality of voice mailboxes associated with a user. The destination voice mailbox is selected based on an evaluation of the first redirecting number and a second redirecting number of the second redirecting telephone device. | 04-22-2010 |
| 20100098188 | IMPULSE NOISE MITIGATION - Systems and methods to mitigate impulse noise are provided. A particular method includes providing a signal from a transmission source to a mitigator. The mitigator checks the signal for complex impulse noise comprising at least a first periodic impulse noise component correlated to a first portion of a sinusoid representing frequency of an alternating current power source associated with the transmission source and a second periodic impulse noise component correlated to a second portion of the sinusoid. The method further includes receiving noise mitigation instructions from the mitigator at the transmission source to compensate for the complex impulse noise. | 04-22-2010 |
