Does Ratchet support Sec-Websocket-Protocol: WSBRIDGE?
We are using https://github.com/orchidsoftware/web-socket which uses Rachet and the socket works with tools like wscat and Chrome plugin Smart Websocket Client but when the service we are needing to use, Nexmo, for live audio feeds they are not able to connect. 

Working with Nexmo's developers they are seeing that they send header: Sec-Websocket-Protocol: WSBRIDGE

And thinking that WSBRIDGE isn't supported, can this be added or should it be working or can we do something to allow it to work?

Thank you.
