hi, I am tuning the FXO analog module on a cisco 2610 router. I have to know the frequence of the disconnect tone in order to disconnect the call when the other end closes. I have asked PTT, but they are not willing to tell me . Who can help me? I am in China. I think it is the same as in Europe. thanks in advance..
