Keep in mind that the examples given here discuss only a single
point-to-point call. Your capacity planning calculations must take
into account the total number of calls that you expect the network to
handle at one time, including multipoint calls. In addition, you will
need to factor in the requirements for any other traffic that the
network must handle.
For detailed information about capacity planning, please refer to the
Polycom white paper, H.323 Bandwidth Considerations, available
at www.polycom.com.
Call Processing Considerations
After documenting your network topology, you will need to define:
❑ Call processing architecture
❑ Gatekeeper identifier
❑ Default gatekeeper
❑ Call routing mode
Defining the call processing architecture is outside the scope of this
document. Please refer to the PathNavigator Deployment Guide in
the Documentation section at www.polycom.com for detailed
information on this topic.
