We are using SIP Carrier for ourside line that supports FAX T.38 option.
The FAX T.38 option is activated per standard in officeserv and MGI/OAS Card.

We tried to send several faxes but it does not work very well. I don't know if Officeserve is using the T.38 standard.

The question is: how does officeserv know that we are sending a fax or when to switch over to T.38. I didn't find any setting.

Thank you

Jonas
