Klaus,
Where do you think that these messages get rejected ?

The BYE is meant to be sent directly between the two
parties right ?
So, if i hangup the Cisco7960 phone that initiated the
call, the PSTN phone returns to a ringing tone a couple
of seconds later. That shows correct operation.
If i hangup the PSTN phone, the call originator remains
connected (whether it is kphone or XTEN or cisco7960)
indicating that a BYE was never received.
To confirm this i ran ethereal on the caller's host that
used kphone...

Any ideas ? Maybe the Cisco g/w does not send a BYE ?
I also used ethereal on the SER host and nothing was
received there either...

Regards,
Lambros
