To use the free cloud PBX, you need to top up your account balance (any amount) on a regular basis. If you do not top up your account balance for three months, using the PBX will cost $5 per month. You will receive a prior notification asking you to top up your account or to switch off the PBX.

The cloud PBX service becomes free after the top-up payment has been made.
