Running 3.0 (44) software. We are having issues with the IP Office rebooting nightly and no being able to receive incoming calls across our PRI. In addition, we have problems with our 5420 sets saying, "please wait". We have to power cycle the entire system to fix the incoming calls problem. For the telephone issues, we have to power cycle the Digital Station Module. Anyone seen these types of issues and does Avaya have a fix?
