We have a Nortel Norstar Plus Modular ICS system and are having an intermittent problem with one or two phones. Phone 1 will get a call and transfer to phone 2. Sometimes it works and sometimes the calls are dropped for no reason at all or sometimes they will go to the general delivery mailbox. Where can I start to correct the problem? Should I go out and buy new phones? Can I switch a newer phone with one of the problem phones? The phones in questions are T7316E phones. Any advice is appreciated.
Thanks in advance.
