[SVN commits to the Asterisk project]

New Revision: 405656

Log:
res_fax: check_modem_rate() returned incorrect rate for V.27

According to the new standard for V.27 and V.32 they are able to transmit
at a bit rate of 4,800 or 9,600.  The check_mode_rate function needed to be
updated to reflect this.  Also, because of this change the default 'minrate'
value was updated to be 4800.

(closes issue ASTERISK-22790)
