Neil, we are investigating your case now. Can you please clarify how you detected this delay? Is it a time when the fax was actually received by recipient or the time you got confirmation by email? According to our logs it took ~17 minutes to send fax from our servers.
Neil, Also, if you could clarify the below questions for us?
1. Could you provide us with the original/sample doc that you are trying to send as faxes
2. Do you have the same problem for all recipients? or for some numbers?
