I am a four person office, with all but one of these individuals working part time. I currently have five lines. I am wanting to place a physical phone in my conference room but do not want to have to pay for another line every month. Is this not possible? If I understand RingCentral correctly, I have to add another line, as there has to be a line for each physical phone. This would put me at six lines, which is major overkill; there is no possible way that I would have four lines in use simultaneous so six lines would be extremely unnecessary.
