TWU employees may need to make personal telephone calls from time-to-time during working hours. Normally, such use does not result in additional costs or damage to TWU and generally will not hinder the day-to-day operations of an office. Incidental use of TWU telephones during working hours by TWU employees for local calls is not considered to be a misapplication of state property and is permissible so long as it does not unduly interfere with the employee's assigned responsibilities or the normal functioning of the department. Long distance phone calls, including the TEX-AN lines, are restricted to official University business. Personal long-distance phone calls at the expense of the University are not permitted under any circumstances.

Support includes:

  • Broken telephone
  • Can’t receive or place calls
  • Make a long distance call
  • Assistance using voicemail or need a voicemail box
  • Make a conference call
  • Add, remove, or move a phone
  • University directory listings

Getting started

Due to COVID-19 affecting normal TWU campus operations, the use of long distance codes is suspended until further notice. Employees can make long distance calls from campus, as well as forward their campus phones to another phone without a 940 area code. Long distance calls made on campus phones are to be used for TWU business purposes only.
