Note
For the external line access code to be dialled
for external calls only, it is important that all
external numbers stored in your handset
directory must contain more digits than the
number of digits required to make an internal
call to other extensions on your switchboard.
This is most likely to occur when you have
local external numbers stored in the handset
directory without the area code. To overcome
potential problems ensure that all numbers
are stored complete with area code.
