Icecom PresenceEngine
Is your communication Online?
In IP-communication online information is
everything, without it its just wild guessing
if your Instant Messaging or VoiP call reaches
the destination. Icecom PresenceEngine is a
server product that provides your network
presence services with extended information.
All-can-do application server? Actually no
PresenceEngine is a J2EE architecture based
server what follows SIP SIMPLE standards. It
has been designed for high performance
availability and performance in presence
functions and to keep your network topology
modular and effective. It also supports XCAP
standards for presence policy management
and RLS (Resource list server) for contact list
synchronisation. If you need presence-aware
Instant Messaging or conferencing services, we
can offer another solution for you.
Scalability
You can easily scale up when your business
grows. PresenceEngine licensing is server
based and you can cluster them when you need
more performance. Solution runs on PC-hardware
and is distributable to multiple
network locations to meet high availability
demands.
SIMPLE as that
PresenceEngine runs on open standards and
interoperates with any 3rd party SIP server
elements. It has an internal database for
storage of user specific parameters. In
implementation there is no need to import any
information to this database, since clients are
transferring all data when first time attached
to the server. XCAP module utilises several
methods to secure user integrity
regarding XCAP policy management. User
authentication can be collaborated with
existing user database by using radius query,
direct DB authentication or direct HTTP digest
from the module. Just route presence related
traffic from your proxy to PresenceEngine and
use any method for XCAP authentication -
could it be easier?
