Summary:                    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.
