Hello Theodor,

first of all you would need to have the configuration of Capro to follow the
scenario. And I guess you will not get your hands on that ;-)

But regarding your problem: please ask Cisco to fix your brand new phone!
According to the standards (RFC3261) the CANCEL message has to look exactly as
the original INVITE (e.g. To, From, request URI, etc.) so that the proxies
are able to route the CANCEL exactly the same way as the original INVITE. But
your phone uses the first few bytes of the topmost Record-Route header. This
complete bull****.

Sorry
Nils
