Hi, I posted this in the hardware section but didn't get any response. Since this is related to trading OTC options, this might be the next best place to post it. Here was my query: Hello, I'm helping a small trading firm set up an options trading desk. As most of the market they'll be trading in is OTC through brokers, we need to get one of those squawk (voice) boxes to talk to the brokers. I was wondering whether the broker provides these boxes to us or do we have to go and buy them. Also, how long does the setup take? Thanks!
