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.

Watch the SIP call flow using ethereal: Are the CANCEL requests that
