Hi Maciej,
default value for restore type is "auto", which means you do not have to
do anything for proper fixing of all messages in the dialog.
Some hints:
1) are you using the rr module for doing record_route and
loose_route ? This is essential for auto restore to work
2) in the outbound INVITE, in the RR header, do you see the vsf param ?
3) the replies and ACK for the INVITE are properly restored?
4) for 200 OK ACK , re-INVITEs, BYE requests, do you see the vsf
param in the received Route header ?
Regards,
Bogdan
