[Serusers] Cancel call Problem

[Klaus Darilion]

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.
