asterisk users - Apr 2007 - Asterisk COLP (COnnected Line Presentation)

Hi,

I would just like to know if any work was ever done on COLP or its
related cousins? The last evidence of it seems to be about 2 years old
when K.Flemming and Olle both showed some mild interest. I am not sure
how well that code would apply to today's Asterisk.

(I realise that this is sort of a duplicate posting, sorry about that.)

Thanks for any feedback.
Steve
