[on-asterisk] SSL certificate in asterisk expires in April this year

[Richard (Rogers @ work)]

Hi,

In my trixbox, the certificate for SSL will expire on  Saturday, April 19, 2008 
10:36:34 PM
Does anyone know how I would get a new one from?
Where is the keystore that stores this certificate and the password to the 
keystore?

My trixbox has Asterisk 1.2.14 svn rev 48468 built
