•Check all line cord connections at the wall jack and at the telephone.
•If the line does not enable caller ID, this service cannot receive caller ID information. Make sure that the AltiGen phone system has activated it in your line and the caller ID format is either SDMF or MDMF.
•The phone receives call information between the 1st and 2nd ring. If the caller hangs up or you answer before the 2nd ring, the phone may not receive the call ID information.
