I have had a couple of IP phones on the system for about 3 years. Just bought some new ones which are Aastra Dialog 4422 loaded with R7C software. I have configured the network settings correctly but phone won't log on. Wondered if there is a software compatability issue? ELU32 firmware is R6A. Not sure what software the working phone is running as can't display it.
