You can dial an emergency number from a Virtual Office phone when the user is not logged in.
Before you begin
You must program all emergency numbers on Communication Manager. For more information about configuring emergency number in the system, refer the Communication Manager documentation.
Note:
Depending on the jurisdiction, you might need to define more than one emergency number. For example, many North American jurisdictions have 9-1-1 for emergencies requiring police, fire services, or ambulances, but support 2-1-1 for mental health or emergency housing.
  1. Press the Emergency feature key or go off hook.
    ADDITIONAL INFORMATION:
    Going off hook will automatically activate the Emergency feature key.
  2. Listen for a dial tone.
  3. Dial the appropriate emergency number configured at the station for the specific jurisdiction. For example, 911 for America, 999 and 112 for United Kingdom.
  4. Device Adapter analyzes the dialed digits against the dial plan in the same way that it does for Avaya Aura® SIP phones.
  5. When a match is found (digit pattern plus correct number of expected digits, where the minimum and maximum number of digits is the same):
    ADDITIONAL INFORMATION:
    1. Device Adapter initiates the call with Session Manager and Communication Manager.
    2. The emergency call progresses with the SIP call handling procedure.
    3. If the call fails at this point:
      • Appropriate messages and tones are provided to the caller.
      • When the caller clears the call, the user endpoint is idle.
    4. Else, if the PSAP does not answer:
      • If the far end fails the call, appropriate messages and tones are provided to the caller.
      • When the caller clears the call, the user endpoint and any remaining call attempt artifacts are cleared.
    5. Else:
      • When the call is answered, features supported at that time are available.
      • When either party clears the call, the user endpoint is idle.
  6. When a match is found (digit pattern plus correct number of expected digits, where the minimum number of digits is the less than the maximum number of digits):
    ADDITIONAL INFORMATION:
    1. Device Adapter initiates the call with Session Manager and Communication Manager.
    2. The emergency call progresses with the SIP call handling procedure.
    3. If the call fails at this point:
      • Appropriate messages and tones are provided to the caller.
      • When the caller clears the call, the user endpoint is idle.
    4. Else, if the PSAP does not answer:
      • If the far end fails the call, appropriate messages and tones are provided to the caller.
      • When the caller clears the call, the user endpoint and any remaining call attempt artifacts are cleared.
    5. Else:
      • When the call is answered, features supported at that time are available.
      • When either party clears the call, the user endpoint is idle.
    Important:
    Device Adapter does not support call back from PSAP to the caller..
  7. When a match is found but the dialed number is not an emergency number, Device Adapter indicates call failure to the user:
    ADDITIONAL INFORMATION:
    • Appropriate messages and tones are provided to the caller.
    • When the caller clears the call, the user endpoint is idle.
  8. When no match exists (invalid digit string), the Device Adapter indicates failure to the user:
    ADDITIONAL INFORMATION:
    • Appropriate messages and tones are provided to the caller.
    • When the caller clears the call, the user endpoint is idle.
