chan_sip _could_ do anything at all. However, since these are not INVITE 
requests, starting something in the dialplan seems a bit out of place. 
However, it's probably the most likely way that this could be 
implemented. However, there does not appear to be any standard (RFC or 
otherwise) behind these messages (although they could be SIP-B, I 
haven't checked), so adding this functionality will be both a bit ugly 
and also very vendor-specific.
