Calls only ring to the console in night mode and not in day mode. The programming seems intact but when I try to change any field in any programming mode it gives me an e11 code and doesn't let me proceed. I cannot find any information on the e11 error code. Has anyone heard of this? I am new to this forum but I have been in the industry since 02/1997. Mainly Avaya, Mitel, Panasonic, and NEC. Glad to be here!
