• Faxes are submitted via the FAXSEND API command (examples can be seen for simple HTML and PHP). Multiple recipients and documents (i.e. all documents are sent to all recipients) can be submitted. The response will indicate success and if so provide a unique status ID for each recipient.
• Immediately or at the future date specified, faxes will begin to be released to the fax servers. This will be on the basis of the priority set and the date of submission, i.e. highest priority first then ordered by date of submission. Note, in the event of multiple faxes to the same recipient, we will only send them one at a time regardless of spare capacity. For each fax released to the queue we will post a '1 Queued' status. Please see the status reporting information for details. 
• Once a fax server begins work on the job, you will receive a '5 Processing' status for that job. The first stage of this process is conversion of the document to a transmittable form. For TIFFs this will not be necessary but for PDFs and other supported formats this will take a short time and naturally longer for larger documents. Following pre-conversion the transmission will begin.
• In the event of a problem sending the fax, we will intelligently retry. This not only means redialling in the event of a busy or human answering but also determining how many pages were successfully transmitted and just sending the rest in the event of a failure mid-call. This differs significantly to most services where you will be notified of the problem but not offered a solution. At the end of either successful transmission or an error not overcome by our retries you will receive a final status post. This will be '10 Ok' if all was fine or a number greater than 10 if not.
