When I was heading marketing for a large coworking company, I set up the entire cloud telephony infrastructure.
This included setting up toll free numbers, hiring a team of customer support executives, setting up Quality control, improving scripts, improving the whole telephony flow for our customers.
I had used a virtual telephony system back then which meant that calls from around the world were hitting a toll free number such as calls from an 520 Area Code number and then routed back to our customer support executives.
One of the biggest problems plaguing the telephony industry is spam and scam calls. When you get a call from an unknown number, especially a toll free number (like 520 Area Code) it is usually a scam and unless you are aware of the caller, it is best to ignore the call.
