Hi, 
I've got an SPA303 3 line IP phone (Cisco) connected to 2Talk. I was wondering how to get the ability to preserve the original caller's ID (if available) on a diverted call from my cellphone's number to my 2Talk number. It used to work on my old SPA942 a couple of years ago but now I can't seem to get it going. I see no mention of Bellcore or anything like it in the configuration (Admin mode with advanced configuration) - via web anyway. 

Is it still possible to do this? Like I said I used to have it working, and I remember a decade ago it used to also work on my cellphone when I had a landline forwarded to it ( the CID would come up (original number) > (diverting number) )

Thanks in advance....
