I am trying to add a video track to a stream, and then call renegotiate() from JsSip. However, when I do this from the caller, it works fine, but when I do this from the caller, it does not work (session end). I looked into the Freeswitch logs and found the following lines:

It seems to work with this FS branch: FS-10089-combining-inherit_codec-and-ice. I tested it using JsSip and UPDATE methods to revise SDP.
