Adjunct/Switch Application Interface (ASAI)

You cannot use PSA on an ASAI link, because ASAI uses a Basic Rate Interface (BRI) port. Do not assign a Class of Service (COS) that uses PSA to an ASAI link.

Bridged Appearance

When you issue a PSA dissociate request for the principal telephone, the bridged appearances of the telephone remain active. The bridged appearances remain active if the telephones on which the bridged appearances appear have not been dissociated.

When a call is made to the principal extension, any of the bridged appearances can alert. If the call cannot alert at a bridged appearance of the principal extension, the system routes the call to the coverage path of the principal extension.

Using PSA you can dissociate request from a bridged appearance. However, the system dissociates the telephone at which the user issues the PSA command, even if the user is on a bridged appearance of another telephone.

Call Management

A PSA dissociate request automatically logs out an Automatic Call Distribution (ACD) agent.

Coverage

PSA does not change coverage path operations. If a station is dissociated, the system routes calls to coverage, unless the calls are forwarded.

Property Management System (PMS)

Do not assign a COS that uses PSA to an extension that is assigned to a room, instead of to a user.

Save Translations

PSA commands cannot be run successfully during a save translations operation. When a reset 3 or greater (reset 4, reset 5, and so on) occurs on the system, all associations revert to the state as of the last save translations operation.

Security Violation Notification (SVN)

If SVN is active, SVN tracks and reports PSA security violations.

Tenant Partitioning

If a telephone is already associated, a user who attempts a PSA associate request at that telephone must specify an extension that is in the same partition as the extension that is already associated with the telephone.

However, any user in any partition can issue a PSA dissociate request at the telephone, if the COS of the telephone extension uses PSA. After the user successfully dissociates the extension, the user can issue a PSA associate request for an extension in any tenant partition.
