If you have that situation, it would be beneficial to have a dial plan set up in your default context to deal with this issue. I usually have a "custom extensions" folder inside of /.../freeswitch/conf/dialplan/default. From there I immediately bridge to the external number, setting your caller I'd and number along the way.

Hi All,
 
When dial an internal number "1234", it will "bridge" or "transfer" to an external number "87654321".
 
And on the caller phone will disply "Outbound Call", also show the number "87654321".
 
I checked the sip message, the info is got from the 180 or 183 message.
 
Sometime, don't want to show the real external number "87654321" to the enduser.
 
How to keep the caller phone displaying "1234".
 
Thanks in advance!
