Learn how to answer calls on your Cisco Wireless Phone 9821. This Help article is for Cisco Wireless Phone 9821 registered to Webex Calling.

Your Cisco Wireless Phone 9821 functions like a standard phone. You can make outgoing calls and answer incoming calls using the phone.

Spam indication for incoming calls

Secure Telephone Identity Revisited (STIR) and Signature-based Handling of Asserted Information Using toKENs (SHAKEN) is a framework of interconnected standards. This ensures that calls traveling through interconnected phone networks have their caller ID signed as legitimate by originating service provider and validated by the receiving service provider before reaching the consumers.

When STIR/SHAKEN support is implemented on the server, the phone can display an icon next to the caller number that reflects the caller's STIR/SHAKEN verification result. There are three types of icons corresponding to the verification status:

  • Verified caller—The phone displays an icon Icon for validated call on 9821 indicating that the caller ID passed validation.
  • Possible spam—The phone displays an icon Icon for unverified call on 9821 indicating that the caller ID cannot be fully verified.
  • Potential fraud—The phone displays an icon Icon for spam call on 9821 indicating that the caller ID failed validation.

These icons help you reduce wasted time answering robocalls and mitigate security risks from spoofed or tampered caller IDs by providing clear visual cues about the call's authenticity.

Answer a waiting call

When you have an incoming call while you are on an active call, you hear a single beep. You can answer the new call and automatically hold the active call.

Press Answer or Answer/Send 9821 Answer button.

When you have multiple incoming calls, select the desired call before pressing Answer or Answer/Send. If you do not select a specific incoming call, this action automatically answers the earliest one.

Decline a call

When prompted with an incoming call, you can decline it by sending a ringing call to your voicemail system (if configured). If your administrator doesn't set up your voicemail system, the call is rejected and the caller hears a busy tone.

If you don't see the Decline softkey, then your administrator has disabled the ability to decline a call.

Do one of the following actions:

  • Single line: When prompted with an incoming call, press Decline or Power/End Call 9821power button.
  • Multiple lines:
    1. Access the Phone 9821 Phone app icon app.
    2. Select a line.
    3. Select an incoming call from the calls list and press Decline.

Block anonymous calls using feature code

When you receive incoming anonymous calls, you can either press the Decline button to reject the call or block these calls by activating the anonymous call block feature using the appropriate feature code. This feature prevents calls without caller ID from ringing on your phone, helping to reduce unwanted anonymous calls. If you choose to decline the call, it will be sent to voicemail if configured; otherwise, the caller hears a busy tone. Blocking anonymous calls via feature code provides a persistent block until deactivated, while pressing Decline handles individual calls as they arrive.

1

When your phone is idle, dial *77 to activate anonymous call blocking.

2

To deactivate anonymous call blocking, dial *87.

After dialing either code, you can hear an audible indication in the call regarding the feature state.

Ignore a call

When you get an incoming call that you don't want to answer, you can ignore the call. The call shows up in your call list.

Make a call using one of the following ways, depending on your preference.

  • Press the Up or Down arrow on the Navigation Cluster.
  • Press the Select button in the center of the Navigation Cluster.
