Why would I be expecting KPML, if I have only indicated that I support 
DTMF-over-INFO?

If I was to expect KPML, I would first need to establish a subscription for 
KPML (or, in our "controlled network", the subscription would be established by 
default, and I would know you are going to send KPML).

Regards,

Christer
