# NP OnDemand - System Requirements

NP OnDemand makes no special hardware requirements on NuPoint Voice systems.

With respect to NuPoint Voice software:

- NP OnDemand works with all Mitel integrations. The mailbox number is the called number provided by the integration.

- NP OnDemand complements NuPoint Voice features defined by FCOS, and does not in any way alter their operation.

- A mailbox created on demand requires the same account space as a regular mailbox. If a large number of NP OnDemand mailboxes are allowed to persist, a system could run out of account sectors.

- NP OnDemand cannot be used with NP Forms or NP Net.
