G'day, I am now to this forum and I am seeking some help please> I am trying to do some analysis of telephone numbers dialed from our sites to determine how many are going to other company sites. We have 35,000 extensions and over 400 sites spread across the State. At each site we typically ask for a range of telephone numbers from the TELCO who supply them in blocks of 100 numbers. THe block of numbers in the ranfge are contiguous but the ranges may not be adject to each other. For instance id I asked for 300 numbers I might get allocated 65000-65099, 66200-66299, 66800-66899. At the moment we have > 2000 of these ranges and they are continually added and deleted as we open/close or relocate premises
I am getting about 18 Million calls per qtr and would like to ascertain if the number recorded by the PABX as being dialed is to one of our sites or External (i.e gone to the outside world).
Min Number Max Number Site 0 70717399 External 70717400 70717499 CYH - The Second Story 70717500 71292299 External 71292300 71292399 Modbury 71292400 73228399 External 73228400 73228499 SADS Dental 73228500 74249999 External 74250000 74250499 Repatriation General 74250500 74252799 External 74252800 74252899 SABME Torrensville 74252900 74252999 External
The result I am looking for is to compare the list of numbers dialed against the range to see if it is one of out sites and the site name
Number-Dialled Site 74250501 External 74252810 SABME Torrensville
I am trying to do this without having to make all the dummy entries that I have currently shown to facilitate a VLOOKUP in Excel.
