Upgrading from our traditional PBX phone system to Crystal Voice VoIP telephony system for our Singapore branch has been a breeze. With cloud IP PBX, we have seen a significant decrease of our monthly phone bills from $550 a month to less than $75 a month now. This is amazing and has saved us a few thousands of dollars a year. We recently moved office and the setting up of our phones in our new office was easy without needing to re-configure our phones, it was just plug and play! Thank you Crystal Voice, we couldn’t have imagined this without you.
