Telephone & Voice Mail Instructions

The College of Staten Island’s Telecommunications department supports the campus wide telephone system. These responsibilities include the maintenance and repairs of all telephone related equipment, as well as managing individual phone extensions, call routing functionality and voicemail.

  • On-campus Calls

Dial four digit extensions for all internal calls

  • Voice Recognition Directory Assistance

Dial 2000; speak the individual’s name you wish to contact.

  • Off-Campus Dialing

Dial 9 + 1 + (area code) + (seven-digit telephone number)

  • Unified Messaging Voicemail

Microsoft Unified Messaging (UM) integrates CSI’s telephones and email and provides for a more efficient means of communication.  UM allows for the integration with other Microsoft applications and provides many collaborative opportunities.

Some of the features include:

  • Accessing voice mails the same way you currently access your CSI email. The universal inbox lets you access your email, voice mail, calendar, and contacts anywhere - and all from one place.
  • Do you need to forward a voice mail? It can still be done from the phone, but now you can also use your smart devices, i.e.: smartphone, tablet or laptop.  
  • Do you need to check your emails?  You can now use your phone and text commands to check your email and calendar appointments.  Both can be read to you over the phone.
