I am transferring to a new department. What is the procedure for obtaining a new phone number?

Answer: Phone numbers are now assigned to people. Similar to the handling of an email address, you keep the same phone number during your time with UH. When you transfer to a new department, there ought to be a phone for you to sign-in to (CX600) or plug-in to (CX300) your computer. Department phone numbers stay with the department. If you are currently signed-in to a phone, sign-out before you move to your new department.
