You should be careful even about doing that if you are on a landline. There is a landline scam where they don't let the call disconnect, so when you hangup and then think you are dialing the bank, you are actually still connected to the scammer.

Always use your mobile phone to make the call (although I'm sure its only a matter of time before even that is compromised).
