Hi Anthony

We are using Aastra 57i phones with the latest firmware (v3.2.2.56 from 
June 2011).

However, it looks like a specific issue with the Aastra 57i as I have 
just replicated the call and cancel situation using a 3CX softphone and 
in this case the CANCEL request gets honoured by FS.

Here's a copy of a failed CANCEL test using the Aastra phone:

Here's a copy of a successful CANCEL test using the 3CX softphone:

sofia loglevel all 9 is on for both tests.
