Yes. Why is it a problem? This a completle legal according to RFC3261.

Naturally our own loose_route function works perfectly with our own 
Record-Route entries.

Completly normal.

If Record-Routing does not work, then i guess your UA (Snom?) is broken. If i 
remeber correct Snom is know to fail with usernames in Record-Route headers 
(dont know if they fixed it allready).
More interesting would be to see the reply from the UA.
