Why I am here today ….
![Page 3: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/3.jpg)
Final Tally:● 670ish
Landlines ● 152 (20ish use licenses)● Analog ● Fax● Elevator● HVAC● Security

So what did our path to this looked like…
![Page 5: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/5.jpg)
2011: Out with Old……...…In with the NewThe only sure thing was the time had come to scrap our analog Avaya phone System and we should move toward a Unified Communications platform.
The existing infrastructure:• Avaya system with 700 phones + • 92 phone Cisco via Call Manager Express • The systems did not play well together or allow
full utilization of functionality for either system.
![Page 6: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/6.jpg)
In 2011 = 2 Phone Systems = A problem
![Page 7: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/7.jpg)
Our Temporary Path = 3 Phone Systems
![Page 8: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/8.jpg)
Our Goal = A single phone system
![Page 9: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/9.jpg)
● Converge three (3) phone systems to one (1)
● Standardize campus handsets
● Drive recurring Hardware Costs down
Objectives:● Upgrade & add
Unified communication capabilities
● Obtain greatest value for initial investment
![Page 10: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/10.jpg)
The Problem...the Cost
1) Ask for more money to accelerate the change2) Phase the costs in over a 3-4 year period3) Look at other alternatives
![Page 11: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/11.jpg)
To Cisco or Not to Cisco… That was the question
• It was really hard not going with Cisco.
• We were mostly a Cisco Shop with small Cisco VOIP presence on campus,
• Cisco CME solution would not scale would have to be discarded to handle our entire campus.
VS.
![Page 12: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/12.jpg)
To Cisco or Not to Cisco… That was the question
Moving to a Cisco solution would have required 3 tiers of licensing for 1) Phones 2) Voicemail boxes 3) Messaging Services including Jabber & Voice to email
VS.
![Page 13: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/13.jpg)
To Cisco or Not to Cisco… That was the question
Cisco extra cost items we wanted:● Attendant Console/ Switchboard ● Voice Recording ● Agent / Call Center CCX● Hardware Cisco’s UCS Chassis thus the
requirement for additional hardware.
VS.
![Page 14: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/14.jpg)
The Alternative● Utilize existing hardware ● Converge three (3) phone systems to one (1)● Standardize handsets across campus● Upgrade and improve our voice/unified
communication capabilities● Obtain the greatest value for our initial
investment● Significantly reduce our recurring costs

virtual environment on existing HP c7000 blade hardware consisting of g8 bl460c blades and virtual connect switches.
● 2 CPUs/dual core, 300GB storage 8 GB RAM very little overhead
● The storage for this environment is the Lefthand p4000 series SAN.

Problems (Part 1):• We are maxing out system capacity with 700ish
Digium phones• About10% of phones time out & must be reset
(reset button or unplug and re-plug) • Digium Phones have a scaling problem past
400ish phones
![Page 24: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/24.jpg)

What’s New in the 6.1 release (Part 2):
• Call Queues (Examples: answering out of sequence & leaving a voicemail w/ call back
• Contacts Import from Outlook & setting a phonebook to push to your users
• Virtualization will eliminate most arbitrary limits
![Page 27: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/27.jpg)
If our user culture was different we could have used softphones for all the 700ish phones and our cost have been price at about $50,000 total.

Things to Remember
Commercial Support is ImportantSam Houston State University 6000 VoIP phone rollout of Asterisk turned into a failed deployment in 2009. After deployment they were forced to move back to a proprietary Cisco solution when they lost key staff with Asterisk specific knowledge.
![Page 29: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/29.jpg)
Things to Remember ● A POE network environment is a must● Solid server hardware is a must install the
virtualized environment
![Page 30: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/30.jpg)
Things to Remember ● I wanted to try avirtualized environment based on
my experience deploying a 250 phone system at a previous institution. In my opinion the Digium appliance hardware is a little underpowered. In the previous case, for example, we immediately had to upgrade memory. I guess the lesson is if you are using appliances, take the recommended specification & bump that specification.
![Page 31: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/31.jpg)
Would I do anything differently….Maybe
Polycom phones for deployment > 400 Digium phones update every time a change is made to the contact information. This causes issue when all the phones try updating at the same time. The Polycom phones only update when the phone reboots.
![Page 32: DRAFT PREVIEW of Casper College Phone System Presentation for Wyoming Community Colleges](https://reader031.fdocuments.net/reader031/viewer/2022030307/58e8c7471a28abc9058b6631/html5/thumbnails/32.jpg)
So is it Possible….
● Yes…○ If you're broke you can still upgrade your phones○ It’s a feature rich system even if you're not broke○ Your organizational culture must be right for
softphones○ Commercial support can ensure long term
success

Are there other alternatives to explore….
