[Asterisk-Users] immediate on fxo

[Jon Pounder]

When immediate is set on a port that is an fxo, what is the meaning of this ?

Will it go immediately to the "s" extension of the context when the line 
first rings, or something else ?

I am looking for a way to stop the line ringing two extra times before 
being answered by the channel bank. (caller id is set to off I believe, and 
the lines in question don't have it anyway.)
