Hi!
I fail to send faxes with 3cx.
Hardware is a Brother MFC-L 2710 DW hooked to a Grandstream HT801, which is provisioned and status page looks fine.

Error message is like this:
Call or Registration to 08xxxxxxx@(Ln.10001@Deutsche Telekom SIP-Trunk 2) has failed. 217.x.1xx.1xx replied: 403 Forbidden; from IP:217.x.1xx.1xx:5060
Help is very appreciated. Thanks!
