HI Here is a question about the fxs of the zaptel card which is set a number to use in the inter as common analog phone. When I also use ${CALLERID(num)}to get it's number, it also could not be done. At this time ,the fxs phone does not get any relation with the outbound which is like PSTN and so forth. It just set the phone number and extension in the * for inter used . Could you tell me
