| Used / Refurbished | Rs. 5,500 – 8,500 | Stable availability in Karachi (Saddar) and Lahore. |
Tech Note for SKYRS: This module is purely “Plug & Play” mechanically, but the 12 additional keys must be programmed in the PBX maintenance software (e.g., KX-TDA/TDE Maintenance Console) to function as intended.
Key Advantages
Cost-Efficient Expansion: Instead of replacing a KX-T7633 with a larger model, adding the KX-T7603X increases the total programmable keys to 36 (24 on the phone + 12 on the module).
No Extra Wiring: The module connects directly to the side of the host phone and uses its existing cable. No additional wall jack or power supply is required.
Enhanced Monitoring: Ideal for receptionists who need to see the “Busy/Free” status of more than 24 internal extensions simultaneously.
