When attempting to fax to international fax numbers you may get a busy tone error or a no answer error. The purpose of this article is to provide steps to take when there are issues dialing international numbers.
Any FaxMaker installation which has a requirement to send faxes to fax numbers in other countries.
Phone providers and PBX/call manager providers and administrators may require different prefixes or dial strings to produce a successful international call. The FaxMaker dial string can use any prefix or characters, but the device to which FaxMaker sends the dial string must be able to make sense of it and use it to achieve the desired result.
For example, some may have a PBX that removes the prefixes applied by users and applies the correct prefix, so many prefixes will work.
Other scenarios where using a modem directly connected to a provider's line may not accept a '+' sign and may require '01' preceding the country code for international calling.
In many cases, it is best to dial from a phone which uses the same PBX or call manager, to see what is acceptable to allow the international call or contact the IT or voice group who manages it.
Unfortunately, due to the many variables outside of FaxMaker, a definitive solution cannot be given, but more guidelines to experiment with various possible prefixes.
Once the correct dial string to use has been determined, you can set this up in the FaxMaker Dialing Options or the string can be dialed by the end-user sending the faxes directly.
Once the correct dial string required by your PBX/call manager/provider is used the international faxes will be sent without error.
