I'm still looking into whether these devices will help me. I'm at the point of figuring out what the unknown unknowns are, as I'm new to telephony. Where are you located? I am in London, UK. I'm aware that due to the likelihood of shipping there's a good chance this won't work out.
It's an older office phone system. Boxes that run a bunch of office phones. Not a mobile phone.
Anyone know of an ESS-5A that needs a home? I really would like to bring one to HOPE in NYC one year.
