[Asterisk-Dev] CO signalling (was: New to Asterisk - questions)

[Gregory Junker]

Heh, all ISDN services are optional, including ISDN itself. ;)

The way it looks is that it's an ANSI standard, which means 
(theoretically) that it should be implemented in a standard fashion 
across switch manfacturers (as far as that term implies). Interesting 
that this has not been done yet, since it ought to be a generally 
desirable feature, I would think (first application comes to mind for 
me, in transferring calls away from the office to a cell phone when a 
user is roaming, and not tying up two lines to do it).
