День добрый!
Имееться смедующая проблема: Циска as5200 при включении или перезагрузке не всегда поднимает трубку. Т.е. - включил питание, она загрузилась - звоню на нее - она выдает сигнал занято.

Вот SH RUN:

isdn switch-type primary-5ess

controller E1 0
clock source line secondary
pri-group timeslots 1-31

interface Serial0:15
no ip address
no ip directed-broadcast
isdn switch-type primary-5ess
isdn incoming-voice modem

E1 0 is up.
  Applique type is Channelized E1 - balanced
  Cablelength is Unknown
  No alarms detected.
  Version info of Slot 1:  HW: 4, Firmware: 8, NEAT PLD: 20

А потом, постояв некоторое время она может нормально отвечать на звонки (а может и не отвечать - все произвольно). Если начинает отвечать пишит в консоли следующее:
00:02:52: %CONTROLLER-5-UPDOWN: Controller E1 0, changed state to up
00:02:53: %CSM-5-PRI: add PRI at slot 1, unit 0, channel 15 with index 0

00:02:54: %LINK-3-UPDOWN: Interface Serial0:15, changed state to up
В чем может быть проблема? Где копать?
