Call rates from College telephones may change as we seek the best provider for the College.

Free calls

The type of calls that are free of charge are:

  • internal calls;
  • calls from College telephones to Mobex (Mobex is the five digit mobile extension associated with the full mobile number of a College mobile);
  • local calls;
  • national calls.

All other calls are chargeable calls. You can also make chargeable calls using a Roaming PIN.

Roaming PINs

A roaming PIN is a unique six digit PIN that is allocated to a specific extension. This code allows you to make chargeable calls using any College telephone. Any calls you make using your PIN will be charged back to the billing extension.
