IntroductionHere, the approach to the problem of "cracking during ISDN trunk calls" Common Cause is a difference between the ISDN clock between multiple connected ISDN lines on one PCI card.
- To get in contact with the ISDN provider with an explicit reference to clocking problems can bring relief.
- Optimally, all connections to the customers should be connected to the same PCI card.
- Alternatively, change the order of ISDN connections.
