When Call Forward, caller ID not pass through to forwarded phone

[Kwang Mien]

Hi,

I have configured call forward when no answer for my extension to forward to my mobile after 20 secs of ringing.
When the caller called my DID number of the extension, the call is forwarded to my mobile after no answer for 20 secs.
However, my mobile shows the DID number of the SIP Trunk.

Can anyone advise how i can configure to show the number of the caller ?

Thanks.

Regards,
Kwang Mien
