Abstract: A system that incorporates teachings of the present disclosure may include, for example, a communication device having a controller adapted to establish communications with a voicemail system over a Public Switched Telephone Network port of the communication device, receive from the voicemail system by way of a broadband port of the communication device an invitation to switch to a video call over the broadband port, transmit a Session Initiation Protocol message to establish video communications with the voicemail system, and transmit to the voicemail system a video message to be recorded by the voicemail system as a video voicemail message. Additional embodiments are disclosed.

Abstract: A system that incorporates teachings of the present disclosure may include, for example, a network element operating in a communication system having a controller element to receive from an initiating party a message directed to a subscriber of the communication system, receive from the subscriber a request to present the message, identify the initiating party supplying the message, transmit the identity of the initiating party to a telephone number mapping (ENUM) system with a request for a communication ID of a presence system that monitors the initiating party, transmit to the presence system according to the communication ID a Session Initiation Protocol (SIP) SUBSCRIBE message requesting presence information of the initiating party, and present the subscriber one or more options to communicate with the initiating party according to the presence information received in a SIP NOTIFY message supplied by the presence system. Additional embodiments are disclosed.

Abstract: A method for determining an amount of time required to download a data file to a wireless device includes receiving information indicating a first amount of wireless bandwidth allocated for the download of the data file, calculating a first length of time required to download the data file to the wireless device based on the first amount of wireless bandwidth allocated, and comparing the first length of time required to a predetermined amount of time. If the first length of time required is less than the predetermined amount of time, the download begins. If the first length of time required is more than the predetermined amount of time, information indicating the first length of time required is sent to the wireless device, a start download signal is received from the wireless device, and download of the data file to the wireless device begins in response to the start download signal.

Abstract: A belt tensioning system for a motor and a belt-driven blower each secured inside an air handling unit. The blower rotatably carries a first shaft, a first sheave and a bladed arrangement being secured to the first shaft. A second sheave secured to a second shaft is rotatably carried by the motor. A belt engaging the periphery of the first sheave and the second sheave urges the first sheave to rotate about the first shaft in response to the motor urging the second sheave to rotate about the second shaft. An adjuster having adjustment means is secured to the structure. Actuating the adjustment means in a direction urges the motor either toward the adjuster or away from the adjuster to vary the distance between the first sheave and the second sheave to vary the tension in the belt.

Abstract: A support system for an air handling unit (AHU) including a first rail supporting the AHU and a second rail supporting the first rail. A vibration isolator is disposed between the first rail and the second rail to vibrationally isolate the AHU from the second rail. The vibration isolator includes a spring secured between opposed spring retainers. An adjusting member threadedly receives the upper spring retainer. The first rail structurally carries the guide member along at least two positions. An angle is secured to the second rail, and the second end of the structural member slidably engages the guide member. Rotating the adjusting member with respect to the spring retainer in one direction compresses the spring between the spring retainers to support the weight of the first rail and the AHU. The angle constrains the AHU to movement along the guide member.
