I mean, (being not so educated in the telephone technology), but to know that there is DC voltage connected to my ZAP-channel. (indicating status = OK)
According to Wiki, "A calling party wishing to speak to another telephone will pick up the handset, thus operating the switch hook, which puts the telephone into active state or off hook with a resistance short across the wires, causing current to flow."
So, I suppose to know there is current flowing, would say I'm connected, but probably not guarantee that I can make calls. So this test would not give me trustworthy results. Or what do you say Tzafrir Cohen? (or others :)

Yes, since I only test lines, that haven't had any incoming calls for some time. Sure, someone COULD be using the line right when I'm trying to use it. How would
I know it was busy through AMI? Is it possible?

I will look into this testserver & testclient. Totally new stuff to me :)
Hope I get it working.
Thanks for the tip Tzafrir !
Nice of you!
