This feature (increasing/decreasing cseq for calls authenticated to the next hop by kamailio) is available with 4.2.0, by using dialog and uac modules.

Let me know if works ok for you, as I did not test it yet extensively.

Cheers,

Does it possible increase cSeq manually (for example remove and then append headers?) for UAC module when send INVITE messages with Auth, or kamailio have pseudovar for this header?
