An SL2100 install with one remote IP phone has been working fine since the install 6 weeks ago. Today I'm told he was disconnected twice yesterday and saw this message on the IP phone's display: "Network Busy. Restarting." Then the phone reboots.

The 2100 Alarm Report doesn't show anything since the last time rebooted it.

In researching this, I found an old thread here about an 8100 that mentions a similar problem. They were told to change the setting in 84-23-02 from the default of 3600 to a new value of 180. 84-23-02 is the IP MLT Subscribe Expires Timer. I've made that change, so we'll see what happens.

Any other thoughts on this? Thanks!
Jim
