DTMF DID |
| Implementing features, see also Manager E Dual-Tone Multifrequency Direct Inward Dialing |
Definition |
| This feature enables users to use direct inward dialing (DID) on non-DID trunks such as analog trunks. This type of pseudo-DID is achieved by suffix-dialing dual-tone multifrequency (DTMF) digits. |
| External calls that reach the system via this feature are released after a timeout if they are not answered. This prevents analog trunks from freezing up. The timer Release if no dialing is activated when the trunk answers. Default time is 10 seconds. |
| An announcement lets callers know that they can use DID. A customized announcement is available in the system. This feature requires an external announcement device. |
Operation |
| The user calls the trunk number flagged as DTMF DID. The system answers. No tone is presented to the user. The user dials the station number and is connected. If the call is not answered within 60 seconds (not variable) the trunk is automatically released. |
| If a recorded announcement has been configured for callers, the caller can be presented with an audio message and can start dialing. During the announcement a Code Receiver is on line to detect dialing. |
| The announcement device is connected to an analog port and must be able to present an open loop to the system at the end of the message. |
| Refer to Section 5.2.10 "Announcement before answering" for more information. |
