Phone system changes at King Edward Memorial Hospital

PLEASE BE AWARE: The King Edward Memorial Hospital phone number prefix starts with a 6 (6458 XXXX)

On Saturday 22 October 2016 the main switchboard number at King Edward Memorial Hospital (KEMH) will change to 6458 2222. All other phone and fax numbers at KEMH using the prefixes 9340 XXXX or 9287 3 XXX will change to 6458 XXXX.

This is due to an essential replacement of the Private Automatic Branch Exchange (PABX) phone system to improve stability and functionality.  The existing PABX system uses outdated technology, has run out of numbers in the same range, and is unstable.

The new PABX system has recently been installed at Sir Charles Gairdner Hospital, and the Queen Elizabeth II Medical Centre, and will be installed at the new Perth Children’s Hospital.

Graeme Boardley, Executive sponsor of the project at KEMH said “the new system offers improved features including video conferencing, better voicemail options, and opportunities to accommodate many new extensions. Staff on the new system will also be able to make internal calls between the three sites, all of which will help significantly improve efficiency.”

The changeover is being carefully coordinated to ensure business continuity.

If you are calling King Edward Memorial Hospital after the changeover date of 22 October 2016, please note that you will have to dial the new numbers.
