Hi,

I’ve been hitting an `InvalidSessionDescriptionError` in Firefox 37 & on  
the latest stable Licode release, as well as on master.

This is a known issue and is already filed at  
[https://github.com/ging/licode/issues/283](https://github.com/ging/licode/issues/283).

Anyone has any clue how to solve this? Looks like something to do with  
`erizo/src/erizo/SdpInfo.cpp`.

Thanks!–

Hi Kaustav,

This problem in Firefox 37 has been already solved in the last commit of  
the master branch.

Greetings
