Building a PCA

Personal Call Assistant

Personal Call Assistant - PCA

Calls to a DN automatically, and simultaneously, call a second (mobile) telephone. The call can be answered on either device. Personal Call Assistant (PCA) requires package 398.

Example: 2222 calls 3333, which is configured with PCA. The PCA extends the call to a second DN, and the call rings on 3333 and 555-4444 simultaneously. The first to answer assumes control, and the other set stops ringing. If the call is not answered, any redirection treatment on either set is invoked (voice-mail).

Note: PCA passes the originator's Calling Line Identification (CLID) to both called party's. The PTT must allow this!

Use the three Flexible Feature Codes (FFC) to activate, deactivate, or change the target DN on a PCA from the set.

  1. To activate or change PCA, enter the PCAA FFC.
  2. To deactivate PCA, enter the PCAD FFC.
  3. To verify the current status of PCA, enter the PCAV FFC.

Enter the prime DN of the terminal, followed by the Station Control Password (SCPW), and #. Listen for a confirmation tone.
This tone indicates that the password and extension match and the procedure was successful. If you hear a fast busy tone, the procedure failed and you must hang up and try again. The confirmation tone is provided only when FFCT = YES in LD 57.
