Dissociated telephones with PSA

Last Updated : Oct 30, 2012 |

When a user requests to associate a telephone with PSA, any other telephone that uses the extension is automatically dissociated. Users can place emergency calls from a dissociated telephone, if a COR is assigned to dissociated telephones on the Feature-Related System Parameters screen.

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

With the dissociate function within PSA, a user can restrict the features that are available at a telephone. When a user uses PSA to dissociate a telephone, the telephone can only be used to:

  • Call an attendant

  • Accept a terminal translation initialization (TTI) or a PSA request

To enable users to make other types of calls from dissociated telephones, you must establish a COR for the telephones.

For example, assume that extension 4001 and extension 4002 are administered on telephones A and B. On telephone A, user 4001 dials PSA Associate Code, followed by the extension and security code of user 4002, the following events occur:

  • Telephone A associates with extension 4002

  • Extension 4001 turns to an AWOH extension (X-port)

  • Telephone B is unavailable

When user 4002 dials PSA Dissociate Code on telephone A, the following events occur:

  • Telephone A dissociates from extension 4002 and is unavailable

  • The dissociation telephone does not restore any previous association with other telephones.

  • Extension 4002 dissociates from telephone A and turns to an AWOH

If you again decide to associate these telephones with the same or different extensions, for analog or digital telephones you must use the PSA or TTI feature to associate with an extension and for IP (h.323) telephones you login with an extension.
