Guardian allows us, to offer you the customer, an immediate cost effective and endless voice and data communication solution.

Medical Messaging

Dispatching is more than just geo-located coordination of operational staff. Effective dispatching requires insight and specialist knowledge of the activity, something the staff at MST Critical Communications has done for a long time. Cellular technology later replaced the business application of the paging service and the business thus transformed itself into South Africa’s leading emergency management service provider for trauma centers around the country.

Today, the Medical Messaging business provides emergency medical dispatching services for hospitals in
both the public and private sector dispatching medical staff on average 500 times a day.
