When I recive email from PBX with voice message in body I see
Content-Type: text/plain; charset=utf-8
and all is good.
But when I recive email with fax message, in email body I see
Content-Type: text/plain; charset=ISO-8859-1
but text in mail is utf-8 codepage.
How I can change codepage in fax email?
I use Yeastar S20 with 18.104.22.168 firmware. PBX recive fax and send it by email.
