Summary:                    [patch] Milliwatt() is off by -11dbm
Description: 
Confirmed on asterisk 1.4.25.1 and 1.6.1.1 that the milliwatt is about
-11dbm 

Standard PC system, T100P T1 card, to Newbridge Mainstreet 3624
using dahdi-linux-complete-2.1.0.4+2.1.0.2
Debian kernel linux-2.6.28
measured with dbm meter from channelbank

its -11dbm at 1.000kHz, and at 1.004kHz

This can be confirmed because it worked perfectly on same hardware before
software upgrade ( kernel-2.6.15  asterisk-1.2.15  zaptel-1.2.13). 

suspect slinear<->ulaw conversion process, can't confirm.

The issue wasn't actually reopened, but I'm not sure that it needs to.

Even though the commit message said the rev2 patch got committed, it
wasn't exactly that.  I modified the volume arg down to what was suggested
by the reporter from testing.
