Making a client search for international dialing codes is guaranteed to cause annoyance, and some may not bother to look. Connect an answering machine to your telephone line. This is not just for taking messages when you are out. People always make mistakes with time zones and you will certainly not make a good impression in the middle of the night. If you are trying to sell work in two languages, make sure you use both of them on your answering machine.
Faxes are quick and convenient for sending letters, contracts and proofs.
But in some countries it can be difficult to arrange a second telephone line for a fax machine. Also, clients in many countries may not be authorized to send faxes to international numbers. To avoid these problems, you can secure a personal UK or U.S. fax number through an online company that provides fax-forwarding services. Such a service will receive your faxes at a number allocated exclusively to you, and send you the fax as a graphics file via e-mail, immediately. These numbers can be dialed from anywhere in the world, and the software required to view your fax is provided when you enroll.
