STEP 1: ASYD - System Data 1, Index 139. No Answer Timer for CALL BACK. Assign 00H. (RAM data is
3FH = 30 seconds.)
System Data 1, Index 68, Bit 0. 0/1: SHF and access code/last digit of telephone number + access code.
System Data 2, Index 0, Bit 0. Is CALL BACK enabled on a per-tenant basis? 0/1: No/Yes.
System Data 2, Index 4, Bit 0. CALL BACK and OUTGOING TRUNK QUEUING [O-2] access
codes are same or separate? 0/1: Separate/Same.

STEP 4: ASFC - Assign a Service Feature Class that allows SFI = 2 to stations to be allowed the feature, CALL
BACK.
STEP 5: AKYD -ForD
