[SR-Users] bad transport for sips uri?

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.

Cheers,
Daniel
