Hi Franz,

thanks for the files!
I'll run some test in the next days...

Some issues I've found in your scenarios:
1. The Service-Router should not be in the 401 but in the 200
2. The initial Route header is not only the content of the Service-Route 
header but the uri of the P-CSCF + the Service-Route header
3. The BYE transaction is not finished by an ACK (ACKs are only part of 
INVITE transactions)
4. You can/should use the same call id for the first and the second REGISTER
