Hi, We are getting a pulsing clicking sound when using siptone phones on a customer network. The called person hears pulsed clicking sounds, whereas the person on the siptone phone hears pulsed hissing. We are using alaw all the way through and there is no codec conversion taking place. Does anyone know what this could be? Tan -------------- next part -------------- An HTML attachment was scrubbed...
