I have anewly created, internal pri. In the other end, we have a server that will call a parent when a child is absent from school. That part works fine. But there is also a feature we'd like to use that allows the parent to call in to check message, so this box needs to answer a call. What would make a specefic number ring on this box? I'm sure you'll need more info to answer this, so if you'd like to try, let me know and I'll post whatever info (configs, etc) that may help.
