Barge fails and results in a fast busy tone
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.
You are disconnected from a call that you joined using Barge
You will be disconnected from a call that you have joined using Barge if the call is put on hold, transferred, or turned into a conference call.
The other party may have call forwarding enabled.
The phone shows an error message when you attempt to set up Call Forward All
Your 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.
