An Alert Call is a specific phone number that you consider important and want to be
alerted to when you receive a call from - or dial a call to - this number.
System administrators set up the Alert Calls button using the Cisco Unified
Communications Manager Administration. Contact your system administrator to get
this button assigned to your phone.
Answer Answer allows you to answer the oldest call that is available on all line appearances on
your phone, including Hold Reversion and Park Reversion calls that are in an alerting
state. Incoming calls always have priority over Held or Park Reversion calls.
Your system administrator sets up the Answer button depending on your call-handling
needs and work environment. Typically, the Answer is set up if you have multiple lines.
