OK, I'm happy to report that I finally managed to get the call transfer to
work with a different softphone application called LinPhone. I will
investigate why X-Lite doesn't work with sending DTMFs, but at least I know
now that my Asterisk setup isn't at fault.

Sadly, I can not share a solution any more detailed than this, the softphone
switch was enough to convince me that the Asterisk server is working
perfectly, it was primarily my X-Lite configuration at fault, so my sincere
apologies for posting this on the Asterisk mailing list.

If I find out how to get it working, I will append that information to the
thread so others can reuse that knowledge later on, I'm sure someone will
appreciate it.

Thanks to each and all contributors who've got me thinking about finding the
problematic part in my setup.

Sincerely,

Frank
