Your config works exactly as I need. Thank you Brian!
I have two more questions about SIP headers, replies etc.

1. Is there a way how to add headers to replies?
If I simply try to prepend "respond" app with "export" of desired SIP 
header, it doesn't work - the header is added to the INVITE, not to 181...

2. Is there a way how to modify SIP headers or - may be - remove headers?

Thanks a lot once more, regards
