you can get attributes of INVITE during CANCEL, but iirc not the avps. 
Accessing INVITE is done via $T_inv(pv) - for example, the r-ruri of 
invite is $T_inv($ru).

An option to share data between different messages is to use hash table 
- in this particular case you can use a key based on callid/from-tag.

Cheers,
Daniel
