IP office locked lines

[dm710]

We have a customer with an IP office 500. Last time they have problems with the external lines. People can't call them and they also can't make calls. When they reset the system (power down), everthing works fine after the reset. I tried a lot of things. De dealer says that the problem was synchronisation and I called KPN to set on continue synchronisation. Still the problem exist. It looks like that the problem mostly exist, in the weekend, when their are not many calls.
Does anyone have a solution for this problem?

This sounds like an ISDN 30 on an old modem.
Is this correct?
The line stays out of service until you make a first call (which ofcourse fails)

BAZINGA!

I'm not insane, my mother had me tested!

They don't have ISDN-30, but ISDN-2 (2 * mv ISDN-2 and 1 * ev ISDN-2)

What is the software version of the IPO?
Is it a IP400 BRI card or IP500 BRI card?
