Nope! The beauty of PENGUIN VoIP Phone service is that you can keep your main phone number and lose the rest. Each phone on your cloud hosted PBX phone system is assigned an extension. Callers can simply dial the main line and then dial the extension of the person they wish to reach. No more buying extra phone lines either. Your system is designed to handle as many callers as there are at all times. The only limitation to the number of calls you can take is the number of physical phones and humans you have to answer them. But your callers will never hear a busy signal again. Intelligent call handling will send callers to voicemail or use time-based conditions to intelligently route calls, even when a human isn’t available to answer the phone.
