Trinity Faculty and Staff. 



Trinity uses a Cisco Voice Over Internet Protocol (VoIP) telephone system for all on-campus voice communications, including the phones found in campus offices. 


How to use

Call on-campus numbers by simply dialing the four-digit extension number and act as campus-wide notification systems in the case of emergencies.


For off-campus local numbers, use 9 before the phone number. 


For off-campus long-distance numbers, use 91 before the phone number.
