Outbound is sysprog-->start or exit--->lines/trunks-->Pri-->number to send-->select how you want to send it.....extension will only send the extension #...extension with base will send the base with extension..ex, base is 610-433-8000 and you make a call from x122, it will send 610-433-8122 and by line is self explainatary. As for caller ID, there is no option, either you have caller ID or you don't. Is your LEC sending you caller ID? You can check through "the unsaid" by tracing the b-channel group. It will show up there. Good luck.
