[Asterisk-Users] Is Asterisk ready for "real" use?

[James H. Thompson]

Actually it seems to depend on the brand of RJ-45 jacks.
I used to work in an office that routinely plugged RJ-11s plugged into RJ-45 jacks.  They had tested
various brand RJ-45 jacks and used those that were tolerent of having RJ-11's plugged in.
However, I agree that its in general a bad idea.
