Table 26: Digital Trunk Configuration Parameters 
Trunk Name 
Configure trunk name to identify the digital trunk. 
Channel Group 
Configure the digital channel group used by the trunk. 
Hide CallerID 
Configure to hide outgoing caller ID. The default setting is "No". 
Keep Trunk CID 
If enabled, the trunk CID will not be overridden by extension's CID when 
the extension has CID configured. The default setting is "No". 
Caller ID 
Configure the Caller ID. This is the number that the trunk will try to use 
when  making  outbound  calls.  For  some  providers,  it  might  not  be 
possible  to  set  the  CallerID  with  this  option  and  this  option  will  be 
ignored. 
When making outgoing calls, the following rules are used to determine 
which CallerID will be used if they exist: 
  The CallerID configured for the extension will be looked up first. 
  If no CallerID configured for the extension, the CallerID configured 
for the trunk will be used. 
  If the above two are missing, the "Global Outbound CID" defined in 
web GUI->PBX->Internal Options->General will be used. 
CallerID Name 
Configure  the  new  name  of  the  caller  when  the  extension  has  no 
CallerID Name configured. 
Auto Record 
Enable automatic recording for the calls using this trunk (for SIP trunk 
only). The default setting is disabled. The recording files  are saved in 
external storage device if plugged in and can be accessed under web 
GUI->CDR->Recording Files.
