Depending on the account type, after an employee's affiliation officially ends with Texas Tech, their enterprise voice service is disabled.

• 4 days after TTU staff affiliation ends
• 121 days after TTU faculty affiliation ends
• 60 days after TTUS staff affiliation ends

This allows for employees to retain their TTU personal phone number for a period of time should they stop working for one department and obtain employment with another.

It is not possible to leave a voicemail message for a removed TTU personal phone number. Callers will hear the following greeting and are then disconnected:

Sorry. That person's mailbox is full. Please call back later.

Then, there are 21 additional days before a number is released into the available pool. TTU personal phone numbers are automatically assigned by the eRaider Account Management System from this pool of available numbers. Individuals cannot choose their own number.
