Having experienced multiple "small business phone systems" (AT&T hard wired system - OK, AT&T SynJ wireless system - TERRIBLE, and a vTech system - almost as terrible) and for basically the same price plus a little bit of configuration time, the Grandstream products worked better, had more features and had much better sound quality than the others. I hope this helps. I bought this system for my office due to the affordable price. It initially had some problems with calls cutting out and poor call quality. I was going to return it, but the quality improved for a short while. The problems came back a week later and I had my phone guy look into the phones, wiring, and telecom installation. He said everything else was good but there was a problem with the phones. We hooked up a different system and viola! No more problems.
A well written script is the cornerstone of any great on hold message. It must capture the caller’s attention, so they remain engaged while navigating menu options or waiting on hold. The script that callers hear can set the tone for the rest of the conversation. It should also be in line with your goals, which can be broken down to 3 main objectives. It can be to inform the caller, promote the brand or product, or just entertain the caller. Most of all, it has to be engaging.
