> Patton Smartnode <=> Asterisk <=> Cisco SPA112
> Incoming Fax from Patton Smartnode.
> Smartnode doesn't include T38MaxBitRate in reinvite and Asterisk thus uses a default of 2400 in reinvite to SPA112.
> According to http://lists.digium.com/pipermail/asterisk-users/2013-July/279964.html this is probably wrong and 14400 should be used as the default.
> Can easily be fixed by rearranging the "enum ast_control_t38_rate" values.
