Get a discount on the Office bundle for 2 months. After registering, enter promo code and top up your account balance.

Phone bundles include outgoing call minutes and virtual numbers, as well as extended PBX features.

To enjoy all of the PBX features, you need to regularly top up your account balance – at least once in three months with any amount. If a user has not topped up their balance in over 3 months, PBX will become a paid service at $5 per month. Such user will receive a notification, and will have a choice to either top up the balance or disable PBX manually.
After the next payment, PBX will automatically become free - $0/mth.
These conditions are not applicable to bundles (Office and Corporation), for these users PBX is always free and has no limitations.
