make sure you are passing the correct callerID to the backend and check once and will work fine.
I have setup all the things and working fine.

Did you change anything on the Client application? or u just change on the server side?

changes in client side may be your ref is not containing the callerID. and check are you getting the callerId on backend side?

Hey, After accepting the call from caller you have to check whether you are getting the callerID in "ICEcandidate"
something like this
{
** calleeId: '928449',**
rtcMessage: {
label: 0,
id: '0',
candidate: 'candidate:2628580718 1 udp 1685987071 145.58.15.120 39111 typ srflx raddr rport 39111 generation 0 ufrag 1tIz network-id 4 network-cost 10'
}
}
on backend if yes then check are you getting the remoteStream or remoteStream?.toURL() on client side.
