## 1801
Common number at automatic outgoing/incoming traffic

The command is used to state the incoming number that shall be transferred to the reroute position for the line.

Furthermore this number is used to build up the public number that is sent out to the line as A (calling) or B (called/connected) number in cases where the internal number is not subscribed in the PSTN-net.

Example: Digits 000 are received from the line, which means that the call shall go to the reroute position for the line (PABX-operator or similar) in accordance with commands 1103 Reroute position at day, 1104 Reroute position at night.

The special analysis in accordance with commands 1801 Common number at automatic outgoing/incoming traffic & 1803 Irrelevant digits at automatic incoming traffic is needed as digit 0 is used internally in the exchange, e.g. to call an outgoing line.

Assuming the extension number series consists of 3-digit numbers beginning with the digit 2 and from the line 3-digit numbers beginning with the digit 0 are received, the following has to be set:

- 1801 = 200 (= incoming common number which should call the answer position programmed with commands 1103 Reroute position at day and 1104 Reroute position at night).
- 1803 = 1 (remove leading digit)
- 1802 = 2 (add the digit 2 to the remaining part of the received number)
