I was wondering if anyone knows what happens when you forward the calls to line A to line B, and then forward the calls to line B to line A. Is this even possible?
-
I've never seen this done, but I'd imagine it creates a loop. When a call is connected to a line with call forwarding, it does first connect to that line before forwarding to the next. I'm pretty sure it'd make both phones ring endlessly before it was disconnected. the loop may break if someone on either one of the lines attempts to pick their phone up, but I'm not sure. I think the delay between connection and forwarding, though, may be enough to cause the two from overloading eachother or causing an error. Is anyone able to test this?

Next on Phones and Philosophy: does the PSTN really exist?

In a Cisco Call Manager system it would create a constant routing loop that would take down your system if proper measures are not adopted. I actually had a customer who wanted me to do that.

well what proper measures would have to be taken? ???

I have seen a poorly-configured mail server take itself out because I was able to forward e-mails to one address and have that address forward back.

I tried this back in the 90's. I forwarded my two phone lines to each other, then called one of them with a cell phone. All I got was a busy signal, but no ringing. I also made a chain of call forwarding with some stores in a mall once. There were less than 10 businesses in the chain, and I think they all did half-rings before reaching the end of the chain. But again, if I forwarded that last number to the first number, I got a busy signal. I was hoping to create nonstop half-rings around the mall.

what if instead of forwarding the first and the last phones in the chain together you physically tied them into each other at the TNI box?

Physically connecting lines is what happens when you terminate a call. I'm not sure if it would be able to pass a foward to the line; it probably wouldn't register as busy if those phones were on-hook, but it would be trying to forward to a line that's already connected, so it just blows my mind.
