The purpose of this questionnaire is to help you collect the information that you need about a customer’s end user phone requirements to provide to that customer a Cisco IPT solution. To obtain the answers to this questionnaire, you can either take this questionnaire and meet with the customer or e-mail the questionnaire to the customer and have them complete it. Customers usually provide some part of the information requested in this questionnaire in their Request for Proposal (RFP).
After you obtain from the customer all the information that is requested in this questionnaire, you should check the available Cisco IP Phone models (a current list of models and features is provided in Appendix A, “IP Phone Models and Selection Criteria”), and identify which models suit the end users’ needs. Based on the number of users and user types at each location, you can calculate the number of phones required for the total IPT rollout.
This section evaluates the end users’ requirements for the Cisco IP Phones. Appendix A lists the currently available Cisco IP Phone models and describes the features that are available in each model. The cost of the Cisco IP Phones ranges from $100 to $1000 depending on the model. It is important to choose the right model because the purchase price has a direct impact on the total cost of the project.
Limiting the number of IP Phone models to one or two in the network reduces operational overhead. If you deploy varying phone models, operational staff has to be trained to support the varying phone models.
The questions in Table D-1 will help you to gather the end users’ requirements and decide on the IP Phone model and features to enable for each user group. Use the employees’ business functions to place them into user groups. For example, the following classification is commonly used:
Table D-1. IP Phone Requirements

|---|---|---|---|---|
1 | Do you require support for Cisco Power over Ethernet (PoE) or IEEE 802.3af inline power? This decision has to be made globally and should not depend on the user groups. | □Cisco PoE □IEEE 802.3af PoE □Both | ||
