Sending A Page
Sending a page using session initiation protocol (SIP) includes receiving a call to send the page, determining a paging group that includes one or more devices based on information associated with the call, where the one or more devices are capable of receiving the page, establishing a connection to the one or more devices using SIP invites, and sending the page to the one or more devices.

determining a paging group, wherein determining comprises obtaining information indicating whether a target device is in use; and
wherein, in a case that the target device is in use, sending the page comprises causing audio on the target device to be augmented with the page, the page being played on the target device as a volume that is lower that a volume of the audio.
18 . The method of claim 13 , further comprising:
obtaining page information relating to receipt or non-receipt of the page at the one or more devices; and
logging the page information.
19 . One or more machine-readable media that stores instructions that are executable to send a page using session initiation protocol (SIP), the instructions for causing on or more processing devices to:
