New Telephone System: Conversion Schedule and Other Important Information

As recently announced, Illinois Tech will be deploying a new voice-over Internet protocol (VoIP) telephone system across the university.

The current Avaya telephone systems are almost 30 years old and has exceeded its life expectancy. The new VoIP system offers many benefits unavailable on the current system, such as superior sound quality, increased portability (no need for call-forwarding), and service mobility (start a call in the office and finish it on the go with no interruption). These additional features are designed to be helpful, especially in this time of remote operations.

The schedule for the university-wide conversion to VoIP will be performed in blocks of extensions, which appear below:

Extensions                                                       Date__________

Numbers starting with 312-567-3XXX………..Tuesday, May 26

Numbers starting with 312-567-5XXX………..Thursday, May 28

Numbers starting with 312-567-6XXX………..Monday, June 1

Numbers starting with 312-567-7XXX………..Monday, June 1

Numbers starting with 312-235-XXXX………..Thursday, June 4

Numbers starting with 312-808-XXXX………..Thursday, June 4

Non-direct-dial extensions (4-XXXX)………….Friday, June 5

** NOTE:  All telephones at the Conviser Law Center (CLC) and on Rice Campus will convert to VoIP on these dates. The CLC will be sending their community members detailed instructions on the conversion process as the relevant date draws nearer.

On the applicable above-listed date, depending upon your university extension, your on-campus, physical telephone will no longer function. Instead, calls will begin to ring via an application on your mobile device and/or your PC/Mac.  Any exceptions to this conversion schedule will be individually communicated.

A few days prior to your conversion date, you will receive instructions on how to download the VoIP system application, which will enable your calls to ring on your mobile device and/or PC/Mac before going to voicemail. If you are unable to install the application on the day of conversion, your calls will be routed to voicemail.

If you wish to personalize your phone setup, e.g. route unanswered calls to another number, the project’s website will have guides on how to do that. If you need further assistance, after June 5, when all extension numbers have been converted to the new VoIP system, you may also enter a Support/Help Desk ticket to receive assistance with your personal phone setup.

If you have questions about the new telephone system or the conversion process, the Office of Technology Services (OTS) invites you to visit the project’s website at In addition OTS will have a phone bank with trained support staff available to answer your questions and ensure a smoother transition. Beginning on the first day of the conversion process, May 26, the phone bank can be reached at 312.567.3988 from 8:30 a.m. to 5:00 p.m. Monday through Friday.
