Subject	Dependency/Restriction
External station numbers	Speed-dialing destinations can contain external station numbers only.
	The external station number must include the trunk group or seizure code.
Translation of station numbers to names	You can assign a name to each speed-dialing destination.
Tenant system	If a tenant service is implemented using toll restrictions, the system does not check whether trunk seizures are authorized. If speed-dialing is used, the system automatically seizes the next free trunk, regardless of whether or not the user is authorized to seize this trunk. As a result, an incorrect system number may be displayed at the destination.   For this reason, users should only implement tenant service via ITR groups.
Entrance telephone	The entrance telephone cannot access speed-dialing numbers.
ITR groups	You cannot enter more than one speed-dialing number range for the same ITR group.
ITR groups	By default, all speed-dialing numbers are assigned to ITR group 1.
