IM Chat service
25
Users of the IM Chat service can set up rules in their personal profile to
route incoming IMs to an address of their choice. Users can join multiple
chat rooms simultaneously with a separate window for each chat room. A
system administrator can configure the system wide parameters listed in
Table 3 "Default IM Chat parameters" (page 25)
using the MAS Console.
These parameters are available by opening the configuration window for
the IM Chat service.

The Media Application Server relies on network intelligence to route SIP
sessions to and from the system successfully. The Media Application Server
does not normally maintain knowledge of users, routes, aliases, or any other
network-specific information except in the case of the IM Chat application.
Therefore, for service requests to route through the network and terminate
on the correct Media Application Server, these service requests must:
•
initially traverse a point of network intelligence, such as the Session
Manager
