If a customer hangs up before you have a chance to answer their call we will email you their phone number, providing it is not withheld. This is a very valuable tool for your company. Imagine the last time you were in a call queue and hung up in frustration. What if a few seconds later that company called you back and apologised for missing your call?! Turn a potentially negative customer experience into a positive one!
This is one of the most beneficial features a small business could want out of a telephone system.
