Phone not working

Hi Pam,
Try these..1...remove your telephone line from base unit and fix it into a working land phone and check whether is it having normal dial tone.If it's having engage tone(beep beep...)remove paralleled phones and re connect to cordless base unit.
2.If line is ok (normal dial tone with full volume) & still display indicates line is busy, your main base unit must be having faulty components inside.Commonly these defects happen in thundering or surges through telephone lines.You have to take full set to a repair shop.

We have a Siemens a38h but it won't display 'caller ID'. We understood that the phone would display who was calling us. Any suggestions?

Just because you buy a CID phone, it doesn't give you CID. You have to have the service from your dial tone provider and it has to be in the same format as the phone. There are two major types, called FSK and DTMF. Most countries use the first, a Bell standard where the ID is sient between the first and second ring as a modem tone, but some countries use a "touch tone" format.

It would be best to call your dial tone provider and ask them if they are sending it and what format.
