PRI Dial Plan 
This setting is used to specify the type of the callee number. The service 
provider will usually verify this. The default setting is "unknown". In some 
very  unusual  circumstances,  you  may  need  set  to  "dynamic"  or 
"redundant". 
Note:   
When one type is selected, you might not be able to dial another class of 
numbers. For example, if "national" is configured, you won't be able to 
dial local or international numbers. 
PRI Local Dial Plan 
This setting is used to specify the type of the caller number. The service 
provider will usually verify this. 
International Prefix 
National Prefix 
Local Prefix

Configure the prefix in PRI local dial plan for each type. 
PRI Indication 
Select the PRI Indication. 
  Outofband: Use RELEASE, DISCONNECT or other messages with 
CAUSE to indicate call progress (e.g., cause: unassigned number or 
user busy). 
  Inband: use in-band tones to play busy or congestion signal to the 
other side. This is the default setting. 
Reset Interval 
The interval that restarts idle channels. 
PRI Exclusive 
This  setting  is  used  to  set  up  the  ChannelID  in  SETUP  message.  If 
enabled, only the specified B channel can be used. Otherwise, select 
one  of  the  channels  in  B  channel.  If  you  need  override  the  existing 
channels selection routine and force all PRI channels to be marked as 
exclusively selected, please enable it. 
Facility Enable 
If selected, transmission of facility-based ISDN supplementary services 
(such as caller name from CPE over facility) will be enabled. 
NSF

Currently  the  supported  values  are  "none",  "sdn",  "megacom", 
"tollfreemegacom", "accunet".
