A second terminal sends a request to initiate a communication session with a first terminal to a server. The server signals the first terminal to initiate the communication session. The first terminal determines an offset amount based upon the redirection timer information. The offset amount is added to or subtracted from a redirection timer value to determine a modified redirection timer value that takes into account time that elapses between messaging exchanged between the server and the first terminal that affects the first terminal determination of an amount of time remaining in a redirection timer of the server such that the determined modified redirection timer value is equal in value or substantially equal in value to the amount of time remaining in the redirection timer of the server.

Communication apparatus and method

A communication system includes a switch device communicatively connected to terminal devices and a computer device. The computer device is configured to initiate a connection to the switch device and, after establishment of the communication connection, initiate a bulk start-up of device monitoring for devices to which the switch device is connected. In some embodiments, the bulk start-up of monitoring can be initiated by obtaining an identification of all relevant devices in a reply to a single request sent by the computer device to the switch device. In some embodiments, the computer device can also be configured to send a monitor stop request to the switch device to stop the monitoring of devices.

Method and system for telecommunication device monitoring

A communication apparatus includes a computer supported telecommunications application ('CSTA') session established between a computing function and switching function that includes a time period where monitors and registrations are preserved by the switching function if the computing function is able to restart the session within that time period after a temporary connection failure. The switching function tracks call and non-call related device activity that occurs from the time a session failure is detected until the computing function is able to restart the application session in a first list. If the computing function restarts that application within the time period, the switching function sends the computing function a list of devices whose activity was detected during the outage. The computing function uses the list of devices to query the status of those devices to reduce the amount of time needed to perform a recovery and less system performance impacts.

Method for optimizing network performance after a temporary loss of connection

A method, device, and computer program product for Session Initiation Protocol (SIP) communications is disclosed. The method, device, and computer program product allow a SIP user agent of a SIP-enabled device to register with a plurality of SIP registrars. The plurality of SIP registration may occur simultaneously or sequentially, based on preference information for the SIP registrars.

SIP user agent with simultaneous multiple registrations

A real-time communications device, a real-time communications system of networked distributed such devices and method and program product for operating such devices. The device includes a personal information manager (PIM), an instant messenger and a Messenger Assistant. The device may also include an e-mail client. The Messenger Assistant automatically provides appointment/status information from the PIM to the instant messenger, which passes status to identified buddies. The Messenger Assistant may also monitor local presence and e-mail and update status based on local presence changes and on incoming e-mail.
