Using a 4 port Perle Iolan device to send call accounting, wakeup calls, and interface a hotel's property management system. About weekly the property has to reset the Perle iolan because they are not getting call records. The property does not appear to have problems with the PMS interface as guest names / checkin/out is processing without complaints. When the Perle iolan is reset, the call accounting system is flooded with records being kept in the Mitel system. Perle says that there is no setting in their system to keep the UDP connection up and running. Any ideas?
