[cisco-voip] port 2000 is getting slamed from IP phone

[Paul Long]

James,

 

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'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're
just seeing normal chattiness. Make sure KeepAlive frequency is set to
at least 30. Setting it to 60 probably wouldn't hurt if the amount of
traffic bothers you.

 

Here is where the setting is located on CCM 4.1:

Service | Service Parameters | Cisco CallManager | Station KeepAlive
Interval

We have ip phones out in the field,  and for about a week we found that
we are getting crazy amount of traffic from these phones hitting port
2000

 

We are running  4.1.2 es41
