For many companies, the tough decision isn't whether to use IP
telephony or not -- it's which vendor to choose. There may be
considerations of current voice or data vendors already at use in
an organization, and each vendor provides a different set of
features and management tools. With all of the variables involved,
the choice may seem daunting.
To help simplify this task, we've collected some of Carrie
Higbie's tips and tricks for vendor selection, garnered from her
"Ask-the-Expert" section. Carrie regularly answers your questions
on the topic of "Preparing your network for VoIP." At the bottom of
this page, we've included links to her answers about comparing VoIP
vendors for further information.
Vendor selection tricks
By Carrie Higbie
@28074 1. My favorite sneaky trick is to check each vendor's Web
site under the press releases section. Find someone that installed
the system a year or so ago. Give them a call and ask them how the
installation went, what surprises they have had since, and how the
current administration of the system is going. Ask if they had to
reconfigure their network, as this is not an expense that would
normally be included. Also, have each vendor provide you with an
ROI/TCO comparison based on your situation.
2. Check whether your local carriers support the same equipment.
Also check to see how they handle priority and quality of service.
I would also recommend looking at market share and the stability of
the company.
3. Do a "bake-off" between the systems. Have each vendor provide
you with a list of their features and benefits -- warranty,
capabilities, interoperability, scalability, etc. What may be
important to me may not be to you, so this method is certainly the
best way to review the features-to-price comparisons.
4. Create a scorecard for each vendor, including all the
information that is important to your organization. Evaluating the
critical things will help you with your decision. Here is a list of
examples to include in your scorecard:
| | Features |
| | Maintenance costs |
| | Warranty periods |
| | Training times |
| | Ease for moves, adds and changes |
| | Availability of local support |
| | Backup power options in the event of a power loss |
| | E-911 capabilities |
| | Interoperability with other equipment |
| | How analog lines are addressed |

What edge would Cisco have over Alcatel?

capabilities?
