asterisk users - Feb 2010 - 1.6.2.1: DTMF trouble with PSTN

Using 1.6.2.1 with a TDM400, attached to internal analog phones and 
PSTN. When I dial out to PSTN, I cannot send tones, like push "1" for 
something stupid. The call itself works, but the DTMF tones fail.

-- Starting simple switch on 'DAHDI/1-1'
     -- Executing [6258013 at internal:1] Answer("DAHDI/1-1",
"") in new stack
     -- Executing [6258013 at internal:2] Dial("DAHDI/1-1", 
"DAHDI/4/ww2156258013") in new stack
     -- Called 4/ww2156258013
     -- DAHDI/4-1 answered DAHDI/1-1
     -- Native bridging DAHDI/1-1 and DAHDI/4-1
     -- Hungup 'DAHDI/4-1'

Any suggestions?

This is DAHDI Tools Version - 2.2.1

Do DTMF tones work for others over dahdi? I'd file a bug, but I'd like 
to make sure it's not just my mistake.
