Abstract
The invention facilitates SIP Enabled devices creating and exchanging augmented data communication messages. An initiating SIP Enabled device may be configured to create an augmented message that includes a call-type and/or a network identification. The augmented data may be configured for a SIP Enabled device by either an administrator or a system user. Furthermore, the system user may customize the default settings either indefinitely or temporarily. Upon receiving an augmented SIP communication request, a receiving SIP Enabled device may identify the request as augmented and subsequently extract the augmented data. The receiving SIP enabled device may be configured to execute functionality based on the extracted augmented data. For example, if the augmented data includes a “hotline” call-type, the receiving SIP enabled device may be configured to play a certain ringtone or display a “hotline” identifier on the device's display.
