A QCC can be the non-local extension that is the single non-local member in a Calling Group.

A QCC operator can manually extend an outside or non-local dial plan extension call to a local extension, non-local dial plan extension, or a destination outside the private network. If the destination is a non-local extension and the call extending (Join) is completed to a busy or invalid number, the transfer can be returned only if the Join took place over tandem PRI trunks. If the Join took place over tandem tie trunks, it is not returned in the event that the destination is busy or invalid.

A QCC Pool Status button shows activity on private network trunk pools as well as on other trunk pools.

A call from a non-local dial plan extension over tandem tie trunks is prioritized as an outside call to the QCC and treated as an outside call for the purpose of the Join function.

To prevent toll fraud, private trunks should not be assigned as Personal Lines on a DLC, nor should a DLC be given dial access to private trunk pools.

DSS buttons can be pressed for non-local extensions. No busy indications, appear on the DSS for non-local extensions.

Single-line telephones can perform the same trunk-to-trunk transfers as other extensions, even though they are prohibited from making trunk-to-trunk transfers of inside or outside calls to local system trunks.
