When sending a fax abroad, you may need to insert a pause within the number.
When communicating abroad, the signal distance is extreme and the signal route complicated. Because of this, you may not be able to connect to a recipient by dialing an international telephone identification number, country code, and the recipient's fax number at the same time. In this case, add a pause after the international telephone identification number. Because adding a pause provides a point where wait time can be added when dialing, it is easier to connect to the recipient.
