Hi, i have a gateway that allows us to call outside and allows calls to reach the extensions from outside, but i have a bunch of extensions that we dont want to be able to receive calls from outside. We have a block of numbers, if any of those numbers is dialed from the PSTN or any external network the call will be routed, through the external gateway, to the PBX so it is up to the PBX to decide if the call should reach the extension or not. there are some restrictions .. i can not have different number segments for the extensions, they all are in the same segment, a given extension could not be allowed to be reached from outside at this time but it may be reachable in a latter time (due to change in the user status in the company), etc ... i tried to put a variable in the directory for a user but when the call arrives at the PBX and the PBX is routing that variable is not available yet and i m having trouble figuring out when that variable is available before bridging the call so i can use it as a condition to route the call. any hint will on how to deal with will help. thanks!
