Chapter 1 – Product Description and Specifications Product Description ® The CallFinder is a DID-to-analog telephony adapter. It brings analog DID services to a key telephone system or PBX that is not DID-enabled. When equipped with the CallFinder, the phone system can route incoming calls directly to end-user extensions. The CallFinder has two DID channels. Each channel is connected to the telco DID line on one side and to the PBX/key system on the other side.
Chapter 1: Product Description and Specifications Prerequisite: the DID Line(s) To operate the CallFinder system, you will need two DID (Direct Inward Dial) lines in your office. You must order the DID line from your local telephone operating company (telco). A DID line allows one phone line to be associated with multiple directory numbers. However, only one call can occur on this line at any given time. DID lines are sold in groups.
Chapter 1: Product Description and Specifications Technical Specifications The CF220-DID CallFinder meets the following specifications: Connectors Four RJ11-FXO/FXS Jacks, One RJ45 - Ethernet Jack Size Power Consumption 6" L x 6.4" W x 1.2" H 15.2 cm x 16.3 cm x 3.0 cm 0.55 kg 1.
Chapter 2 – Sample System Introduction The Widget Vacuum Cleaner Company wants to use DID lines for its Field Support and Purchasing Departments. Alas, the company’s PBX is not equipped for DID service and a new PBX will not be in the budget anytime soon. This chapter shows how this fictitious company might use Multi-Tech’s CF220-DID CallFinder to solve its problem.

Chapter 3: CallFinder Server Installation 5. Resetting Admin PC to Its Regular IP Address In step #2 above, you recorded the original IP address of the administrator’s PC and then reset it to the IP address required to allow communication with the CallFinder unit. You must now set the IP address of the administrator’s PC to a value that allows you to reach the CallFinder at its new IP address. 6.
Chapter 3: CallFinder Server Installation 7. Setting Administrative Functions Go to the CallFinder Phone Book screen. Figure 3-7: Phone Book screen a. Administrator Row: Specifying DID# and PBX Extension • The first row (marked Administrator) of the Phone Book screen, is always for the party who performs the ‘administrator’ function. Even if the Name field of this first row is changed (which is permissible) it still pertains to the administrator function (which includes receiving call-log emails).
Chapter 3: CallFinder Server Installation 8. Setting Up the Mail Server The CallFinder uses a mail server to send, by email, call log reports to the administrator. An email is also sent to the administrator each time the CallFinder is powered up. In all cases, you must specify the address of the mail server and the email address of the administrator. Some email servers require authentication before allowing the CallFinder access.
Chapter 3: CallFinder Server Installation 9. Configuring the CallFinder’s Channels The CallFinder’s channels direct inbound calls to their proper destinations. a. In the CallFinder software, go to the Channel Configuration screen. b. Under Channel Configuration: Channel 1, enter the values that match the characteristics of your DID phone line in the fields provided. Four parameters relate to the DID line coming into the CallFinder channel.
