We also need a function to cancel outgoing faxes that have been submitted through RingCentral. Our users sometimes send outgoing faxes to the wrong phone number (using email to @rcfax.com). When they do it repeatedly by mistake, they need an option to cancel the fax so that they are not bothering recipients' voice lines.
I forgot to mention, for this Cancel-Fax function, we would need outgoing faxes "In-Progress" and "In-Queue" to both be viewable in a list (the call-log?) and can be selected, then cancelled. Currently In_progress outgoing faxes are viewable in the call log, but they cannot be cancelled. Outgoing faxes that are in-queue (ie. being received by email and being rendered) are not viewable anywhere. For example, I had one user had a problem with her email and resent the same email faxout repeatedly 30 times - it would have been nice to be able to cancel them all in the queue before they were sent out. (and before the user received 30 rendered confirmations )
