Need more users or simultaneous calls? D30 adds 100 users and 30 concurrent calls per module on supported PBXs. EX08, EX30, S2, O2, SO, B2 and 4G LTE provide connection interfaces; they do not replace a D30 capacity upgrade.

P560 supports one D30 and one expansion board; P570 supports two of each. P520/P550 cannot take D30. Send your exact PBX model and hardware revision so we can confirm compatibility.
