Avaya phone ringing every morning

[jlacke]

This is my very first post. My boss has a avaya partner 103g16 system in his home. within the last couple of weeks, the phone in his office will ring every morning at 4am. he has to answer it and hang it back up or none of his other phones will work. I went to his house and the batteries needed replacing, which i did. thought this would fix his problem but it has not. has anyone else had their phones ringing on a schedule. any help would be greatly appreciated..
