Good afternoon . I'd like to speak with Tom Smith .   I'm afraid he's away from his desk at the moment .   Do you know when he will be back ?   He's away on a business trip . He won't be back until some time next week .   Is there some way I can get into contact with him ?   The best way to reach him is by cell phone . I'll give you his number .   Thanks . And could I have his e-mail , just in case I can't get him by phone ?
