It's a yoyo, goes up and down when the idle timer, then
immediately it goes back up.
What's causing it to go up? There should be no traffic. No
routing protocol, no keepalive
As5 - dialer type = IN-BAND ASYNC NO-PARITY
Dialer pool 1, priority 0
Idle timer (120 secs), Fast idle timer (20 secs)
Wait for carrier (30 secs), Re-enable (15 secs)
Dialer state is data link layer up
Interface bound to profile Di0
Time until disconnect 7 secs
Current call connected 00:11:39
Connected to 111111 (111111)
Di0 - dialer type = DIALER PROFILE
