What does it mean if the Cisco IP Phone shows an error message when you attempt to set up Call Forward All?
Your Cisco IP Phone may reject your attempt to set up Call Forward All directly on the phone if the target number that you enter would create a Call Forward All loop or would exceed the maximum number of links permitted in a Call Forward All chain (also known as a maximum hop count). Ask your system administrator for details.
Why can't I complete a call on my Cisco 7925G IP Phone?
You might not be able to complete a call on your Cisco IP Phone because: your phone is out of the wireless network access point service area; you must log in to the Extension Mobility service; you must enter a client matter code or forced authorization code after you dial a number; or your phone has time-of-day restrictions that prevent you from using some features during certain hours of the day.
What to do if the softkey that I want to use does not appear on my Cisco IP Phone?
The softkey you want to use might not appear on your Cisco IP Phone because: you must press Options and scroll to reveal additional softkeys; you must change the line state (for example, place a call or have a connected call); or your phone is not configured to support the feature associated with that softkey.
What does it mean if the main screen is not active on my Cisco 7925G?
If the main screen is not active on your Cisco IP Phone, one of these messages might appear on the status line: * Network busy: Not enough available bandwidth exists in wireless network to complete this call. Try again later. * Leaving service area: Phone is out of range of its associated access point and wireless network. * Locating network services: Phone is searching for a wireless network access point. * Authentication failed: Authentication server did not accept the security credentials. * Configuring IP: Phone is waiting for DHCP to assign an IP address.
What happens if I am disconnected from a call that I joined using Barge on my Cisco 7925G IP Phone?
You are disconnected from a call that you joined using Barge on your Cisco IP Phone if the call is put on hold, transferred, or turned into a conference call.
Why does Barge fail and results in a fast busy tone on my Cisco IP Phone?
Barge might fail and result in a fast busy tone on your Cisco IP Phone because: you cannot barge an encrypted call if the phone you are using is not configured for encryption (when your barge attempt fails for this reason, your phone plays a fast busy tone); or you cannot barge a call on another Cisco Unified Wireless IP Phone.
Why does CallBack fail on my Cisco IP Phone?
CallBack might fail on your Cisco IP Phone because the other party might have call forwarding enabled.
