I see the exact same problem when making calls from a Sipura SPA-2000.
The problem does not occur when calling from a Cisco ATA-186.
I've tried comparing the cancel messages between the 2 devices, but only
found 1 difference. The ATA makes the INVITE and the cancel with
user=phone appended, and the sipura does not. I'm not sure why that would
make a difference, though, as long as the CANCEL matches the INVITE...

I can't see any problem in the config file. Which
clients do you use?
Put log(1,"...."); messages into your config and watch the logging
messages in /var/log/messages during the CANCEL processing to find out
where the CANCEL request is beeing lost.
