Question

Questions about Fax statuses and enqueued faxes expiration

Hello.

Where can I find a more detailed documentation describing all of the fax statuses, what is their meaning? Most importantly, I would like to know which ones are the ‘final’ ones, i.e. they will not change in the future.

I haven’t found it in the docs. I searched API reference (there was a list of statuses, but no description), developers guide and few articles on support page, but they looked outdated. 

 

Second question - for how long does RingCentral store sent faxes until they expire? Is there some timeout set? I mean for example when the fax is sent successfully, but not delivered yet, because, for example, the recipient’s number is not available. For how long such fax will wait for delivered/received status?  How long we should wait to get a notification about its status change?

I found this article: https://support.ringcentral.com/article-v2/Troubleshooting-fax-via-email-send-issues.html?brand=RingCentral&product=RingEX&language=en_US
 

  • Wait five minutes per page to determine if sending has failed. Graphics-heavy faxes can take five minutes or more per page to send.

  Thanks for finding this, that is something that we can base our internal business logic on!

 

If the recipient is unreachable, the fax is marked as sent until three automatic retry attempts are made. After the third attempt, it moves to the Failed list

So, does it mean ‘Sent’ is not a final status after all? (because it can still be changed from Sent to Failed)
That is really making us a difference…
 

If you send 1000 faxes from 10 extension, the batch API will be a game-changer.

Yeah, you are right. Unfortunately, there is an issue with RingCentral .NET SDK that we are using and because of that we are not able to use batch API: https://github.com/ringcentral/RingCentral.Net/issues/78

Hi ​@Tyler850957020, any update on this? It’s really important, as our app is going to production soon and we have our internal logic based on the information, that ‘Sent’ is the final status.

We are doing just like you advised here:

I would say as long as you received a final state, you can stop waiting for any more states.

But if ‘Sent’ status can change, this means we cannot do it like that.

Don’t overthink. Nobody said it’s not a final status.
