A system and method for controlling how images are displayed on a display screen of a portable computing device changes the orientation of the images on the display screen when the orientation of the portable computing device changes. The portable computing device is determined to have changed its orientation when it tilts beyond a reference angle that separates a first orientation from a second orientation. If the portable computing device is rapidly tilting back and forth across the reference angle, the value of the reference angle is changed to be either larger or smaller. This prevents the images from rapidly switching back and forth between two different display orientations on a display screen of the portable computing device.

Systems and methods for handling the processing of multiple SIP transactions that have been requested at substantially the same time can involve establishing a priority order for processing the SIP transactions, and then individually processing the SIP transactions based on the established priority order. One or more SIP transactions having a lower priority can be held in a SIP processing queue of a software application until the processing of SIP transactions having a higher priority has been completed. Each time that the processing of a higher priority SIP transaction is completed, the next-highest priority SIP transaction in the queue is submitted for processing. Also, where possible, two or more SIP transactions in the queue may be consolidated into a single SIP transaction.

A system and method for controlling how images are displayed on a display screen of a portable computing device changes the orientation of the images on the display screen when the orientation of the portable computing device changes. If the orientation of the portable computing device is changing only infrequently, the orientation of the images on the display screen may be rapidly changed when the orientation of the portable computing device changes. If the orientation of the portable computing device is changing relatively frequently, the orientation of the images may not switch until after a delay period has expired after each change in orientation of the portable computing device occurs.
