A model of an integrated unified communication network using public switched telephone network gateways and cisco unified communication manager server
Abstract
Communication requirements are constantly evolving in recent times demanding flexibility and
response mechanism in controlling deployments need for everyday connections. It is a necessity
in business today and a well designed unified communication networks facilitate smooth flow of
information. An effective and efficient communication network gives an enterprise competitive
advantage and reduces operational costs. In my study area, we have in place installed PSTN –
PABX and VOIP – CUCM that run in parallel and investment complete in both set ups. It’s
therefore very necessary for integration so that we have a unified communication network.
This project identifies the challenges of having a parallel VoIP and PSTN systems, proposes a
solution on integration of MGCP, H.323 and SIP gateways with CUCM and designs a model to
determine its applicability.
Unified communication will be used to transmit voice services in the internet environment and
legacy closed Public Switched Telephone Networks. My main discussion is about UC, Gateways
design issues, how to measure efficiency, reliability, latency and packet mismatch from the
transmitter and receiving end and also delay and Jitter, and determination of measurements using
delays within the Internet Protocol - SLA (Service level agreement).
I have looked at telephone systems namely legacy Public-Switched Telephone Network
and Internet Protocol telephony that are extensively examined to come up with Unified
Communication by measuring of our University of Nairobi voice networks/services, this is
achieved various models and real experiments. Resulting solutions show that the unified
communication is more efficient in terms of performance in the current technology
