Device Adapter supports the Predial state for 39XX phones.
  1. The user enters digits using the keypad; the Device Adapter collects them.
  2. When the user selects a line appearance, the Device Adapter analyzes dialed digits against the dial plan obtained in the same way as Avaya Aura® SIP phones.
  3. When a match is found (digit pattern plus a valid number of digits, greater than or equal to the minimum number of digits and less than or equal to the maximum number of digits):
    ADDITIONAL INFORMATION:
    1. The Device Adapter initiates the call with the Session Manager and Communication Manager.
    2. Call progress conforms to SIP call handling (speech path cut through, tones, and so on.).
    3. If the call fails:
      • Appropriate messaging and tones are provided to the caller.
      • When the caller clears the call, the user endpoint is idled.
    4. Alternatively, if the called party does not answer:
      • If the far end fails the call, appropriate messaging and tones are provided to the caller.
      • When the caller clears the call, the user endpoint and any remaining call attempt artifacts are cleared or idled, as applicable.
    5. Else:
      • When the call is answered, features supported at that time are available.
      • When either party clears the call, the user endpoint is idled.
  4. When no match exists (invalid digit string), the Device Adapter indicates failure to the user.
    ADDITIONAL INFORMATION:
    • Appropriate messaging and tones are provided to the caller.
    • When the caller clears the call, the user endpoint is idled.
