Query: Caller ID is incompatible with other Phones

If you have any other non-siemens phone with caller ID plugged into your home then the Siemens phone will only randomly show you the Caller ID. According to Siemens support this is an issue with their Caller ID software. I found it unacceptable that such and expensive phone could not support the Caller ID function if I had other phones with Caller ID. Other than this problem the phone worked fine. I had even bought 3 additional extensions until I discovered the Caller ID problem.
