In essence, these systems must rely on much more than stan-

dard SIP to make them work together.

Nevertheless, SIP offers new options for multi-vendor inte-

gration within an IP telephony environment based on open

standards. First, when needed, a specific user agent (a client

device such as a PDA phone) can be connected to the PBX

through SIP. Next, through federation services, you can support

basic connectivity between different vendors’ PBX systems

using SIP. Soon, SIP will enable enterprises to combine multi-

ple PBXs into a single system, which reduces complexity for

both users and administrators.
