[asterisk-users] Extension Numbering

[Norbert Zawodsky]

Hi again,

as I wrote before, I'm new to Asterisk. And so, many many new questions
pop up .....
For example:

I have here a very small telephony system. We have only 5 (or so)
extensions. (4 phones, 1 fax).
So I wonder if there is disadvantage if we use only 1 digit extensions
("1" for boss, "2" for shop, "4" for the fax ...)

I think I can remember something from the "Asterisk-TFOT" book saying
that one must not use 1-digit extension numbers. But I can't remember
that very well and can't find it in the book any more....

Regards,
norbert
