I have a question about SNR. We have setup a demo of 7.1 in our office. There´s one thing I can´t understand, whenever a phone is configured with snr the phone keeps on ringing until the timeout is reached, even if the snr number has answered the phone. As I have understood, this is the correct behavior, but I don´t understand why my deskphone keeps on ringing until the timeout has been reached?!?
