[Freeswitch-users] calls to some registered webrtc endpoints results in NO_USER_RESPONSE

[Babak Yakhchali]

Hi
I'm using webrtc with chrome and sipjs as client on freeswitch 1.10.
Calling to some endpoints results in NO_USER_RESPONSE. I've not access to
client systems and it makes debugging the problem harder. this is the
freeswitch log for one of those calls:

Does NO_USER_RESPONSE mean that invite is not reached to the client browser
or it is reached but no reply is received? can it be related to network
problems or NAT?

any help would be appreciated
thanks
