architectures for ip telephony deployment
DESCRIPTION
Enterprise communications systems have come a long way in the past 30 years. Now the important issues for developing an architecture for IP telephony deployment include: architectural & design attributes of each platform, customer benefits and advantages, the emerging role of unified communications, the evolution to a wireless mobile communications platform, current and developing communications standards and open source solutions. Understand the past--and the present--trends of communications systems.TRANSCRIPT
