Been playing around with both a Cisco 7960 and 7961 on 3CX version 12. Sets appear to be working properly with the exception of the time and date at the top of the 7960, it is missing altogether. Just a black stripe across the top with 3CX on the right. Looked over the configuration file and nothing stands out, as being out of place, when doing a comparison to some other file examples I found on-line. This set is using the configuration file generated by 3CX and is unchanged with the exception of deleting the settings for keys 2 through 6, which were simply duplicates of key 1. It didn't work before I did that either. Has anyone else seen this?
