two channels for one Client

I have modified the fayeClient to have setter and getter for the channel, i want to send on a channel and listen on another one(in/out channels). the sending channel doesn't need to listen and if i create a new FayeClient i must connect to the server a gain, but its not working now and doesn't get any data. please, do you know any solution to stop listening on the "in" channel?
Thanks.
