10.0pt;font-family:Arial;color:navy'>Besides the normal Skinny call-signaling
traffic on port 2000, there is a heart-beat mechanism (KeepAlive/KeepAliveAck) that
may be generating the unexpected traffic you&#8217;re seeing. The CallManager
tells the phones how often to send KeepAlive. Maybe someone accidentally
changed it from the default of 30 seconds to something like 1 second, or maybe
you&#8217;re just seeing normal chattiness. Make sure KeepAlive frequency is set
to at least 30. Setting it to 60 probably wouldn&#8217;t hurt if the amount of
traffic bothers you.<o:p></o:p></span></font></p>
