The first two lines of the file is ignored and is used for description of columns in Excel. (The order of the rest of the lines is not important.)

First column

• "in" Translation used for incoming calls, the destination number will be matched with "Public" and replaced with "AlphaCom" number.

• "bi" Translation used for both incoming and outgoing with the above rules.

Second column

'*'  If no match found use this entry (Can only be used for "in" or "out" not for "bi")
'-'  When used for "in"-AlphaCom number, the reply on SIP will be "404 not found". (Use it with public number "*", to reject all undefined numbers).

If no match and no "*" the number will be sent as is to AlphaCom.
