You need to use the '-' and '+' flags for adding/removing ICE candidates.
i tried by calling rtpproxy_offer(co1sp+r) on invite from jssip. that caused replacement of jssip candidates with mediaproxy-ng candidates and callee got this kind of sdp:

since callee does not support ice, it replies with this kind of sdp:

i then call rtpproxy_answer(co2SP+r) on it in order to add mediaproxy-ng candidates to the reply going to jssip, but i get the error:

how could this error be related to +/- parameters?

There are also issues with mediaproxy-ng when you try to have multiple streams. An audio only call or a video only call should work, but SDP with two m-lines has never worked for me.
yes, that is likely the problem. did you configure your jssip client somehow to use only one media stream?

it was easy. in custom.js:
Settings = { videoDisabledByDefault: true };
after that i was able to make call between jssip client and regular sip client.
