TigerTel's primary mission is to provide Faculty and Staff with economical telecommunications services. In fulfillment of that mission, we provide faculty and staff an opportunity to subscribe to a service that offers an easy and economical way of placing long distance calls from campus telephones. Details of the long distance service follow. ELIGIBILITY: Faculty and Staff are eligible for either service. AUTHORIZATION NUMBER: The TigerTel Office will allow each Faculty and Staff to choose their own 4-digit pin number to be used in conjunction with their ID number. Authorization numbers must be kept confidential and each person is responsible for ALL CALLS charged to his or her personal number, regardless of who placed the calls. You may not use your authorization number for accepting collect calls, placing person-to-person calls, sending telegrams, or for "900" service calls. UNAUTHORIZED CALLS: The University does NOT authorize any person using the University's 9+ service to accept collect calls, charge third-party billed calls, or "900" service calls to any University telephone number, including the residence hall telephones. The TigerTel Office and the telephone companies involved will investigate unauthorized charges to the University. We invoice all charges to the person or persons responsible for charging the calls. We may levy service charges of up to $25.00 per invoice to recover investigation costs. Legal action may result if it is determined anyone has attempted to defraud the University or the telephone company by making unauthorized calls. You may be charged for unanswered calls if you let the phone ring for over 30 seconds. In order for us to keep our rates low, we must charge for these calls because we pay the vendor a bulk fee which is for the time that we actually use the lines. TigerTel is an auxiliary service of the University and operates on a self-supporting basis. In keeping with our mission, and our need for fiscal soundness, we may respond to periodic rate changes enacted by the vendors making corresponding adjustments in our rates. BILLING: Monthly bills are sent via email.  Please let us know if your email address changes. PAYMENTS: TigerTel Long Distance bills are due and payable upon receipt. An account is delinquent if not paid after 25 days from the billing date. Delinquent accounts are subject to suspension of service. Accounts will be reactivated upon request after full payment has been made. In most instances, service will be restored the same day payment is received. a $10.00 service charge will appear on the next month's bill. SECURITY: You should immediately notify the Telecommunications Office at 656-0332, or the University Police Department at 656-2222, if your authorization number is lost, stolen, or discovered by other persons. You remain financially responsible for all calls until they make notification. The TigerTel Office will issue a new number to replace the compromised number.
