I bet this is a really basic question with a really simple answer....
Say I have extension 1234.
Externally, it is rung with 02 9876 1234
Internally, just 1234
Say somebody internal dials the full number 0298761234 - it's going to get routed out to the carrier, then come back in.
There are 3 reasons this is undesirable:
1/ it gets charged
2/ it uses up a port (even if only briefly?)
3/ the recipient doesn't get the caller's name pop up on their screen (or vice versa).
How do I fix this?
Do I use the ARS digits dialled form?
say,
(Assuming i have all 100 numbers in 9876 1200-1299)
02987612 followed by 2 --> ? (Where do I route it to if I do that...?)
