Summary:                    Fax detection broken when upgrading from 1.6.0.9 to
1.6.0.15
Description: 
I have a system that has an analog fax machine connected to a DAHDI line,
and Asterisk performing faxdetect on incoming DAHDI calls.  In 1.6.0.9,
this works as expected and automatically detects faxes and sends them to
the fax machine.  In 1.6.0.15, I am getting an error in the console that
Asterisk is trying to send the fax to extension "ÿ", which is an invalid
extension (since my dialplan is set expecting the extension "fax". 
Reverting to 1.6.0.9 fixes the fax detection behavior without any
configuration file edits.

FYI just a 'me too', I'm getting this in 1.6.1.12 with pretty much the same
debug:

chan_dahdi.c: DTMF digit: f on DAHDI/1-1
chan_dahdi.c:     -- Redirecting DAHDI/1-1 to fax extension
channel.c: Soft-Hanging up channel 'DAHDI/1-1'
channel.c: Scheduling timer at (0 requested / 0 actual) timer ticks per
second
channel.c: Scheduling timer at (0 requested / 0 actual) timer ticks per
second
pbx.c:     -- Sent into invalid extension '?' in context 'incoming' on
DAHDI/1-1

Oddly, after getting a bunch of fax tone voicemails from someone, I did a
test send of my own from remote and it went through to the 'fax' extension
properly...  But all subsequent tests so far have failed every time.
