It is my understanding that Cisco didn't bother implementing this 
functionality into their SIP firmware. However, as you have described, 
this feature does work when using CCM.

chan_skinny (and chan_sccp - which btw, will become the same channel 
driver soon) will eventually support this feature.

If you (anyone?) have any motivation for Theo and myself to make 
Asterisk's SCCP support go to the top of our to-do lists, please contact 
either one of us off-list.
