Purchasing or upgrading your business phone system is a demanding process. The best
approach is to have a procurement plan that lists all the assumptions, benefits, cost
considerations and other influencing factors.
The purpose of this checklist is to walk you through the process of purchasing a new phone
system or upgrading an existing system. It also provides a number of sample questions to ask
yourself at various points.
1. Conduct a comprehensive analysis of your telephony/networking infrastructure. Answer the
following questions to define your system:
a. How many employees are there in your organization?
b. How many sites or regional offices are there in your organization?
c. What are the details of your existing phone system — manufacturer, number of lines,
connections and so forth?
d. What are your current broadband connection details — bandwidth, type, lines and so
forth?
e. What are existing traffic demands on your voice and data networks?
f. What type of servers does your system run on — manufacturer name, model number,
operating system and other details?
g. What is the ratio of inbound to outbound calls?
h. What is the percentage and average number of internal, local, long-distance and
international calls per month?
i. How many remote or mobile users do not have a local office?
2. Define your business requirements clearly. Prepare a list of critical as well as optional
business needs. Be sure which optional needs can be negotiated for a lower cost.
3. Define your investment timeframe and budget. Estimate the cost of the project (budget)
and prepare a tentative plan. You should keep in mind the total estimated project costs or
estimated costs per user per month.
4. Conduct a cost-benefit analysis to select a solution model (on-premise or cloud-based) that
best meets your requirements. Ask yourself these questions:
a. Do you want to outsource your telephony support services and focus more on your
core business?
b. Are you looking for a long-term integrated business communication solution and want
to control your telephony infrastructure?
5. Look out for the hidden costs. Ask the following cost-related questions to avoid any
hidden costs:
a. What startup costs are there beyond setup and equipment fees?
b. Are there any costs related to licenses of supplementary software such as SQL and
Windows?
c. Are there any unexpected components of a consultant’s salary?
d. What are the additional costs for upgrade?
6. Compare vendors and solution options and ask for requests for proposal (RFPs). Ask for a
demo or proof of concept (POC). Make sure you get these from at least three to four vendors.
7. Ask for a single point of contact (SPOC). The SPOC will assist you from the vendor side
throughout the implementation process and beyond.
8. Shortlist the final vendor and have a detailed and an unambiguous contract/service level
agreement (SLA) in place. Based on demos and pilot phase performances, select the final
vendor. Contract termination policies and SLAs should be clearly defined, with a focus on the
vendor’s support policies.
9. Pilot installation and company-wide rollout and beyond. Get the vendor to deploy the
solution over a test network. If the pilot phase goes well, roll out the telephony solution
company-wide. A rollout should happen in a phased manner. The larger the enterprise, the
more phases the rollout requires. After implementation, it is essential to schedule end user
on-site training with the help of the vendor.
