SIP Communications For Dummies, Avaya Custom Edition
56
Applications will not need to be customized to account for
new SIP capabilities. Rather, common libraries (such as
dynamic linked libraries (DLLs) in Windows) will contain
function calls that know how to query presence servers and
return rich and meaningful results.
Here’s an example: A factory assembly line worker is viewing
the parts needed for an upcoming order in an inventory pro-
gram, and notes that there is a shortage. He can immediately
view the presence of the line manager and procurement man-
ager of his own company, and possibly even that of the parts
supplier, from within the inventory management application
itself. Using this data, the worker can communicate status to
the individual who is most likely to be able to act quickly.
Integration with Business
Applications
Taking the scenario described in the previous section,
“Presence-Enabled Business Applications,” a step further,
SIP will enable the line worker to click-to-conference with all
contacts that are present, firing up a collaborative conference
call to discuss the inventory problem. Open Web services will
even allow the inventory application itself to check the pres-
ence of all relevant contacts, and interact with a SIP-enabled
audio bridge to proactively out-call to the parties, removing
the need for a human to start the process. In fact, each partici-
pant will have mini-applications (that provide a view into
the part of the application being discussed) operating within
his conference calling software. These mini-applications will
provide views back into the inventory application, permitting
participants to submit queries or make changes in the appli-
cation. Cool huh!?
When coupled with unified communications across multiple
access devices, presence will fundamentally change the way
people communicate.
