title: How can I increase the default ringing time on a phone using asterisk
body: <p>I have an asterisk pbx setup on my server. We call to phone numbers using our pbx asterisk 11. The default ringing time on the phone numbers seems to be very low around 20 seconds. Is there any way in asterisk to increase the ringing time, if yes then please let me know how can I do this.</p>
