Introduction:
In versions prior to CCA 2.0, Analog FXS ports would auto-register and keep reappearing in User Extensions tab after they were deleted. This document describes how to configure analog FXS ports as either common area or fax phones that do not appear in the User Extensions tab, using CCA 2.0 or above.
Caveat
Non-user analog FXS ports cannot use features such as voicemail, call transfer, call forward or conferencing. They also cannot me watched or monitored by other IP phones.
Procedure
For UC500 in factory defailt
1. Run Telephony Setup Wizard
2. In Configure Analog Station Ports (FXS) screen, select Common Area Phone/Fax radio button
3. When Telephony Setup Wizard completes, the FXS ports will be removed from the User Extensions tab.
For UC500 with existing configurations:
1. In CCA, select Configure > Ports > Analog Port Settings
2. In the Role dropdown, select "Common Area Phone" or "Fax" depending on what device you want to connect to the FXS port
3. Enter any descriptions and click Apply. The FXS ports are removed from the User Extensions tab.
4. (Optional) Select Configure > Telephony Voice > Analog Extensions to modify the analog port extension numbers
