Can we get an update on this? This is high priority since it is blocking usage 
on Firefox.  Also seeing this on windows too.

Hi
I'm also having this error with firefox when the call is terminated.
I'm attaching the console output.

It looks like the following change in Firefox is breaking SIPml5:

"Unexpose the removeStream function on the Peer Connection object temporarily"
https://bugzilla.mozilla.org/show_bug.cgi?id=844295

SIPml is calling removeStream when terminating a call, which results in an 
error.
In the SIPml5 source I replaced:

this.o_pc.removeStream(this.o_local_stream);

with:

if (SIPml.getNavigatorFriendlyName() !== "firefox") 
this.o_pc.removeStream(this.o_local_stream);

Hope this helps.

Thanks a lot. In my case the error is gone when call is terminated.

We also removed the calls to removeStream() when working with Firefox, which 
allowed proper call termination.
