We're just wrapping up deploying MiCollab with NuPoint and NuPoint fax. (I know, I know. It's 2021 and we're still faxing)
I can receive faxes without issue.
I can send faxes reliably, except for two problems.
1. I never get the confirmation email for a successful fax.
2. Every hour or so, it re-sends the same fax.
I do get an error report email if there's a problem that keeps the fax from working at all, so I know that email is functional.
It seems as though NuPoint can't tell the fax was successful, so it is keeping the fax in the queue and retrying.
Any idea what would keep nupoint from recognizing that the fax was successful?
