Ring Timeout 
Configure  the  number  of  seconds  to  ring  the  user  before  the  call  is 
forwarded to voicemail (voicemail is enabled) or hang up (voicemail is 
disabled). If not specified, the default ring timeout is 60 seconds on the 
UCM6510,  which  can  be  configured  in  the  global  ring  timeout  setting 
under web GUI->Internal Options->IVR Prompt: General Preference. 
The valid range is between 5 seconds and 600 seconds. 
Note: 
If  the  end  point  also  has  a  ring  timeout  configured,  the  actual  ring 
timeout used is the shortest time set by either device. 
Auto Record 
Enable  automatic  recording  for  the  calls  using  this  extension.  The 
default setting is disabled. The recording files will be saved in external 
storage  if  plugged  in  and  can  be  accessed  under  web 
GUI->CDR->Recording Files. 
Skip Voicemail Password 
Verification 
When  user  dials  voicemail  code,  the  password  verification  IVR  is
