We have a BCM400 using Release 3.6 Build 2.2 software. I cannot pickup any external calls using directed pickup, group pickup or answer dn. Directed pickup and answer dn will work on internal calls, but not external. I am very new at phone system programming, so the answer is probably very simple, but I'm getting frustrated by it. I've read a lot of the documentation, but I'm just not getting anywhere that way. Any help would be appreciated.
