peter,

when jssip client calls regular sip client, i made the same
rtpproxy_offer(co1spr)/rtpproxy_answer("co2SPr") calls as before, and
rtpproxy_answer resulted in the same error as before. (below)

my mediaproxy-ng is from current git master.

how does your tests differ from the above, since you have got it
working?
