Welltech SIPPBX 6200A - Manual (Page 54)

- 54 -
the Extension’s caller ID to this Trunk, if you set empty here.
Note:
z Normally, SIP From URI will contain the Extension’s calling
ID and SIPPBX 6200A’s IP address, but some ITSP may
reject this call due to some security issue. You can modify
the Calling ID and IP/ Domain in the fields of [External
Server Address] and [Outbound Caller ID] when the call is
going to the Destination (Trunk) via the SIPPBX 6200A to
avoid such security issue.
z If you set a Welltech FXO gateway as the Trunk, you can
simply use the default Trunk 888 and 889 as the FXO’s
register number.
z For the FXO gateway, you may just only configure Trunk
Number, Password, Host, Dial Plan, Keypad, NAT Traversal
and RTP Mode.
z If you set the ITSP as the Trunk, you may need to set the
following configuration: Port, External Server Address and
Outbound Caller ID.
Caller ID Display
Name When inbound call is coming from Trunk, such as 888. The
caller ID Name will be the “PSTN number” or “888”. Specify this
will use the current setting instead.
Comment You can enter a 20 bytes note for each Trunk here.
CLIR Support CLIR means "Caller Line Identification Restriction". It is a
proper noun. It is a feature to hide the caller's number. For
example, ext 101 call to ext 102. But 101 won’t like to show the
caller ID to 102. So 101 can activate this feature to hide the
caller ID. When 102 got a call from 101, the LCD of 102 should
display "Anonymous".
