Operating Ways and Feature Codes
Inward Transfers
To transfer a call to an internal phone, EVM will take the following actions:
1. Sends out a hook-flash if ADM_5_9937 _[xx0x] or [xx2x] is specified. If not, starts Step 3.
2. If SYS_4_5 _[2] is specified, waits one second and then starts Step 3. If not, starts the dial tone
detection:
- When the dial tone is detected, start Step 3.
- When four-second silence is detected, restarts Step 1, but hangs up after the third time.
3. Dials the feature code specified in SYS_6_1 .
4. Dials the phone number.
5. Waits for the Tone Detection delay, the length of which is specified in SYS_7_3 .
6. Handles the call, according to the result of the tone detection. The transfer mode is determined
by the Ring Duration option.
- Blind Transfer (Option 01)
- If 5-second silence or any tone other than the Error tone is detected, releases the call.
- If the Error tone is detected, retrieves the call.
- Unsupervised Transfer (Option 00)
- If any tone other than the Busy tone or Error tone is detected, releases the call.
- If the Error tone or Busy tone is detected, retrieves the call.
