thanks so much, that seems to work!

I had to change it to:

where

dateTimeOrigination >= @StartInt

AND dateTimeOrigination <= @EndInt

AND (finalcalledpartynumber = '386' OR callingPartyNumber = '386')

to get it to work correctly.

Also, in the conversion, is it suposed to be -4 or -5?

select @StartInt = datediff(second, dateadd(hour, -5, '1/1/1970'), @StartDateTime),
