Ah, thanks - Would have been too easy to blame Snom for everything :)
You've been a great help, I will do some tests with your suggestions and
will report back about the success.
Maybe someone should update the example etc/ser.conf.m4 and use a
different approach to detect if an uri is really a private or just a
nated target. I know, I know I could be the someone :)
Thank you again,
Bernd
