Welltech SIPPBX 6200A - Manual (Page 22)

- 22 -
Extension’s caller ID to this Trunk as default value, if you set
empty here.
Note:
z Normally, SIP From URI contains 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
via the SIPPBX 6200A to the Destination (Trunk) to avoid
such security issue.
z If you set a Welltech FXO gateway as the Trunk, you can
use the default Trunk 888 and 889 as the FXO’s register
number.
z For the FXO gateway, you may just 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 configure: 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 input a 10 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".
