[asterisk-dev] About Ringing Time out

[FRANCOIS]

Hello 
I am using the Asterisk version 1.2.7.1  I found that the ring time out is
set to 30s. I mean when phone A calls phone B, and the user of phone B
doesn't pick up the call in 30s , it goes on busy. How to increase this time
out value? Which file or which procedure should I follow up. I have tried to
find out the answer, but can't get it.
Thanks in advance for your Help.
