You may wish to set the following parameters in your peer configuration for 588. ignoresdpversion=yes directmedia=no I use Spandsp FAX successfully. I have also attached an analogue Fax Modem to the FXS port on an SPA8800 and an HT-502 and have been able to receive faxes on them when I last tested, the SPA8800 like the HT-502 are now in storage. Looking at the User Guide for the Vigor 2701 there is an option in the configuration to enable T.38 mode, did you enable it?
