Hey,
I don't think this is something that laserfiche supports natively, and any solution you get will depend heavily on the infrastructure of your client.
This may help as a starting point, its not a direct solution but it does have some of the building blocks you may need. https://www.codeproject.com/Articles/1159834/Send-Fax-with-fax-modem-in-Csharp
Depending on what documents you are trying to send you may be able to generate the document in a workflow download it to a local path on the server(or maybe use a file stream?) then call a modified version of this code to trigger the fax parsing the file into the FaxDocument body.
This is all theoretical, if I had the time id do some testing for you. Hope it helps.
