CUHK Telephone System Change to 5-digit Extension

previouspausenext

The 4-digit to 5-digit extension numbers migration work of the CUHK telephone systems will be carried out on 2 January 2012 (Monday) from midnight to 7:00 am. During the period, all services for the phones and fax machines under the old PABX System and the new IP Phone System will be suspended.

Please note the following changes after the migration:

All internal extension numbers will be 5-digit after the migration (adding ‘3’ in front of all pre-existing 4-digit extension numbers).

The original extension numbers ‘53xxx’ and ‘55xxx’ will be changed to ‘33xxx’ and ‘35xxx’ respectively.

Called parties will see 3943 xxxx as Caller-IDs for all calls from CUHK telephone systems.

Some settings such as speed-dials, call-forwarding, voice mail passwords under the PABX System and speed-dials of the IP Phone System will be reset. Please refer to the webpage www.cuhk.edu.hk/ip-phone/ for details.

To preserve the environment, all departments/units are advised to save paper while updating their contact numbers (with the prefix 3943) in letterhead, business cards, etc. Reprinting should be avoided if possible.

Should you have any inquiries on the migration, please phone the hotline 3943 8877 or e-mail ipt@itsc.cuhk.edu.hk.
