I've been using mediaproxy-ng with JsSIP on Chrome
for a couple of months
now. It works fine for me and I was running a live demo using it for this
at AstriCon two weeks ago.
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?

Hi Juha,
You need to use the '-' and '+' flags for adding/removing ICE candidates.

New subject: mediaproxy-ng failed to rewrite sdp from jssip ws client
Hi,
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.
Regards,
Peter

New subject: mediaproxy-ng failed to rewrite sdp from jssip ws client

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.
