[Freeswitch-users] How to calculate PDD for a call

Hi again,

Today when I calculated the PDD with ngrep:
I got following ngrep trace :Only invite and 183 is displayed here (note the
time stamp):
######################################################
U 2008/10/31 02:58:47.480059 xx.xx.xxx.xx:5060 -> fs.fs.fsfs.fs:5060
INVITE sip:12127773456 at fs.fs.fsfs.fs SIP/2.0.

U 2008/10/31 02:58:49.982140 fs.fs.fsfs.fs:5060 -> xx.xx.xxx.x:5060
SIP/2.0 183 Session Progress.
######################################################

In my code I got 2540 figure in "progressmsec" variable, for above test
call.
As previously told we are getting this in microseconds, converting it into
seconds will give 0.0025 seconds.

But above ngrep shows that it is minimum 2.5 seconds.

So I think  PDD given by  "progressmsec" is in milliseconds and NOT
mircoseconds.
Is it correct?

Thanks
MSP
