Maybe you have a nat box on the way, which is trying to be smart and fix

Contacts are
used to advertised wherebouts for subsequent in-dialog
requests coming back to your UAC. For that reason, I don't entirely
understand why the UAC includes Contact in CANCEL at all -- all in all
CANCEL is used to discontinued estabslishment of a dialog. Anyhow,
it should not matter the Contact content is invalid since there is no
use for the header field in this case at all.
Sorry, just realised that in a half-awake state I typed rubbish. I meant
that the 'call-id' was not rewritten - don't know why I mentioned contact!
(In the INVITE to the Cisco it is blah(a)213.x.x.x and in the CANCEL to Cisco
it is blah(a)10.x.x.x
