Hello, do you have the INVITE and the 200ok corresponding to this ACK? I need to see the R-URI of INVITE as well as the contact in 200ok in order to analyze why sips appears in ACK.
SIPS requirements are sort of a mess, probably the best would be to let it for config to decide when to allow forwarding or not in case of sips URI.
