[Asterisk-Users] VXML_URL and Cisco 7960 Phones?

I tried to get that working as well and also found it was not available in the SIP image. You can't do pushes either to the phone like you can with SCCP.

It's my understanding, although I've no direct experience, the function
does not exist in the SIP images.

The limitation is highly likely related to Cisco marketing plans and not
to real design/programming capability, etc. (How else would one sell 
proprietary systems?)

Anyone have a disassembler?
