Hi Stefan & Juha,
I did some research and found that response codes 180 until 183 may
include an SDP for early media. Although it's rare in the case of 181
and 182.
I think it's safe to check if there's a body in the reply and the
response code is between 180 and 183 to relay the invite.
hm, I found the original patch a little too complicated (why not do the
reinviteCaller where it is done for 200 reply? and probably also only if
!sip_relay_only). What do you think about the attached one?
Stefan
