Caller ID Caller ID GuardianTelecomAdmin (TechnicalUser) (OP) 12 Oct 06 18:42 How do I program the switch to make the phones display caller ID? RE: Caller ID disturbedone (Vendor) 13 Oct 06 11:58 Nothing. It just works. As long as the telco is sending it, it will be displayed on the screen of the digital phones. If you're using analog phones, make sure they're compatable in your country with the CLI standards (not some cheap knock offs you've picked up somewhere).If you're getting WITHHELD on the screen of the phone then the caller has withheld their number and you can't force it to be disalayed.What type of lines to you have - BRI/PRI/analog? RE: Caller ID ksphoneman (Programmer) 15 Nov 06 20:41 The MLDT phones must be assigned as Type 3 for 12 button or Type 4 for the 24 button. Type 1 and 2 are for non display phones.The analog stations need additional equipment that is not standard with most F9600s.
