Hi, I have a paton 4554 with 1 ISDN line. On the ISDN line i have 1 master number en 4 did's. 3 of the fore did numbers are for businnes but there is one number for my private office. The incomming calls are routed tot the right extension This isn't a problem because for each did you can set a extension to send to. The problem is the outgoing calls. I really would like to use one of the did number for my private office. Standard i can set my patton in the outbound rules or voip lines. I cant find any possibility to use a specific did from that patton. When i call on my private line he is always using the master number of m ISDN line instead i could set the one i want. Can some one help me. I'm using 3cx ver.7.0 with the patton 4554 gateway.
