Are you sure the line has long-distance capability? You must check that the line that you are using has long distance, or out-of-state, capability. To do this, plug a regular telephone into the same outlet that the modem is plugged into and attempt to dial the number. BE SURE TO CHECK THIS! Users report several busy signal problems each week, and it very often turns out to be caused by exactly this. If the line is capable of long distance dialing, check the other items described in the following paragraphs.
Dialing: EssentialFax dials exactly what you tell it to dial. The phone number that you must use is the same as if you were using a stand-alone fax machine or just dialing from a phone. This means you must be careful about how you enter the phone number. The phone number consists of the following items, in this order:
If you are in an office and need to dial 8 for an outside line, then the software must also dial an 8 for an outside line. You must enter this information in the dialing rules or directly into each fax number.
If you must dial a 1 for long distance, then the software must also dial a 1, and this must be in in the Dialing Rules or entered directly into each fax number.

Additional things to check
Some phone numbers and calling card numbers involve pauses at various points for messages, and so forth. To bridge any such pauses, insert commas in the dialing string. A comma tells the modem to pause for 2 seconds. Use 2 commas for 4 second pause, and so forth. See How to tell the modem to pause while dialing a number for more information.
If you receive a recorded message when dialing, this is coming from the phone company - not from the modem or the software. It generally means there is an error of some sort in the number being dialed.
If you receive a busy signal, the modem is reporting to the software that the line is busy. In most cases, it is just exactly what it says it is, and you should wait for the number to become un-busy. However there are exceptions to this, and this article on Busy Signals might help.
