I just had a thought.
We find it difficult to Jam over the internet - due to latency.
As you all probably know its down to buffering into packets - sent - received - un-packaged - buffered and out it comes.
Now on the old phone system - all analogue - no delay.
I think I am correct in that the current phone system is possibly almost Analogue even now - so maybe we could hook up over the phone???
