VoiceHost allows as many lines as your soft or hardware phone can handle, many VoIP phones can handle more than one line at a time.

If you are on a call and another line rings, the phone will alert you to another call by flashing a 'line light'. Don't worry if you can't answer the other line, as the call will be directed to voicemail if it is not answered.

This feature is enabled by default. To answer another call just place the first call on hold (See Call Hold) and answer the other call, by pressing the flashing line button.
