Hi - Caller ID just works, it's not something you need to turn on. It sounds as if your Service Provider isn't sending you the number in the first place (it's something you have to ask for). Whatever the "Caller Number" is will be sent through to the phones.
What type of interface are the calls comming in on? Analog (FXO) Pri? If they are comming in on an FXO and the gateway is configured as an MGCP gateway then you will not be able to pass callerid. You can config the gateway as h323 and be able to pass CID. If you are using PRI then the Telco is not providing you with CID. As an aside how many other users here wish that Cisco would support CID on an analog MGCP gateway? We have quite a few small offices with only a few pstn lines, and it is a PITA to set these gateways up as h323 rather than MGCP.
