my customer has a partner 308 with a small 4 mailbox voicemail. it uses selector codes to go to call groups. they called me and said the codes weren't working. i called in and sure enough it was an invalid entry. i reprogrammed them in again and it worked. today they called again and said it wasn't working. i had to program the selector codes in again. i didn't lose anything else. is the thing just wearing out. thanks. dave.
