we have a pilot number set up for reception extension (700), and we have six lines for reception extension (699,1001,1002,1003 etc).
when reception call outside the cluster through PSTN, out side people get say 180 555 (700), but when reception call internal extension, then phone screen display 699.
when we dial the reception (699) from internal extension, then 699 gets translated to 700, and if we dial 700 from internal extension then it rings fine.
But we want that when reception dial any internal extension, it should display 700, instead of 699 or 1001,1002 (in case of dial from other lines).
Any help would be appreciated.
