Add a ResendFax(sFaxDetailsID) method that allows to resend an outbound fax (previously failed or not).
Otherwise, when a failure occurs, QueueFax needs to be called again thus upload the files to send.
We have implemented a "Forward_Fax" API call https://www.srfax.com/api-page/forward_fax/ which can be used for both forwarding a fax by FaxDetailsID or re-sending a fax.
We have this is the queue as well. Once gain we will inform you when implemented.
ForwardFax(sFaxDetailsID, toFaxNumber) should also be implemented.
