Introducing I-Phone
IP Telephony Services
for the
University of Florida

I-Phone is a new solutions-offering presented by OIT-Telecom that takes advantage of the convergence of voice and data networks. 
The I-Phone service is part of the “services-to-wallplate” model that is offered by OIT-Network Services and is designed to ultimately provide an enterprise communications solution for the University of Florida.

What is IP Telephony?
IP Telephony, also known as Voice-over-IP (VoIP), represents a new method of providing telephone service. Historically, telephone systems have used dedicated equipment to provide only telephone service. The equipment includes telephone switches, circuits to connect the switches, telephone sets, and so forth. Rather than using dedicated equipment, IP Telephony will use much of the same infrastructure as a data network. It will achieve this by converting sound into small packets of data and transporting them via the Internet Protocol (TCP/IP) between telephone sets.

There are various ways to implement IP Telephony and they include the following options:

1.       Replace circuits (trunks) between telephone switches with VoIP.

2.       Replace the telephone sets, dedicated telephone lines and smaller telephone switches with IP Telephony equipment.

OIT-Telecom is primarily focusing on option "2".  In this scenario, the telephone set actually plugs into the data network "jack" rather than a telephone "jack." As part of the “services-to-wallplate” model, the network infrastructure and management will need to be in place so that your I-Phone service will be ensured the highest quality of service.

When will on-campus IP telephone service be available?
Now --- as part of the “services-to-wallplate” model, I-Phone service is currently available.  Current projects that have deployed I-Phone service include the new Rinker School of Building Construction building and the Health, Pharmacy and Nursing Professionals (HPNP) facility (via HealthNet).  Upcoming projects will include the Fisher School of Accounting Building and the Constans Theatre Addition.

Description of I-Phone deployment:
The current I-Phone deployment consists of Cisco System’s AVVID technology.  This converged technology includes the use of four distributed, physically redundant Cisco CallManagers.  The CallManagers operate as a single cluster and provide a current capacity of approximately 5,000 devices.  OIT-NS and OIT-Telecom have also deployed Cisco’s Unity server for voice mail features.  A unified communications offering that integrates voice mail and email will be provided as a future service.  Each core PoP location has vlans for IP Telephony.  The voice vlans are secured using access lists defined on each core PoP. 

All production
I-Phone sets are in campus “service-to-wallplate” buildings and are connected with Cisco switches capable of providing in-line power insertion.  Access to the public telephone network is provided using two physically redundant Cisco 6608 VoIP gateways, each connected via the BellSouth SmartRing to PRI circuits.   These Gateways also provide conference bridge resources for the voice conferencing capabilities available with this service.

Advantages of IP Telephony:

1.       Single cable and backbone infrastructure supporting both Voice and Data

2.       Decreased cost of telephone moves (see below)

3.       Reduced Centrex services line costs.

1.       Open systems architecture and non-proprietary devices - With standards, many people will be able to create applications

2.       Unified Messaging – voice mail, email accessible seamlessly through various interfaces

3.       WEB enabled call centers - It will become easier to integrate communications capabilities like web pages, telephones, pagers, voice-mail, e-mail, etc.

4.       Corporate Directory and other portal services from your I-Phone.

5.       Integration of video and teleconferencing:  Large scale teleconferencing is available today using IP telephony services via the video MCU provided by OIT’s Video and Collaboration Services unit.
