# Country settings

The settings for adapting your communication system to country-specific circumstances are to be found here.

## Own local prefixes

Your own regional prefixes need to be entered so the communication server is able to interpret incoming and outgoing numbers correctly. If for example the local prefixes of an incoming call match the system’s own local prefixes entered here, they are truncated and shown accordingly on the phone.

Table 1. Settings for own local prefixes
Parameter | Explanation
International prefix | The international prefix has to be selected so an international connection can be set up from one particular country. Enter the prefix of your own country here. (Example for Germany: 00)
Country code | The country code has to be selected so an international connection can be set up in one particular country. Enter the code for your own country here. (Example for Germany: 49)
National prefix | The national prefix has to be selected to be able to set up a connection from one region to another within a particular country. Enter the prefix of your own country here. (Example for Germany: 0)
National destination code | The national destination code has to be selected to be able to set up a connection from one region to another within a particular country. Enter the code for your own region here. (Example for the Berlin region: 30).
Note: In some countries the national prefix and the national destination code can also be dialled in the system's own region (e.g. in Germany) or must be dialled as mandatory (e.g. in Switzerland). In these countries these fields can be or must be left blank.

## Loop break signalling and call identification (CLIP detection):

The following parameters apply to the signalling of internal analogue terminals with regard to your own communication system.

Table 2. Loop break signalling settings
Parameter | Explanation
Flash maximum | Maximum time in milliseconds at which the communication server interprets a loop break from internal terminals as a control character (Flash).
Flash minimum | Minimum time in milliseconds at which the communication server interprets a loop break from internal terminals as a control character (Flash). Shorter loop breaks will be detected as pulse dialling.
Disconnect from | Minimum time in milliseconds at which the system interprets a loop break from internal terminals as a release signal (go on-hook).
Alerting signal type | The communication server is capable of sending the call number (CLIP) of incoming calls to analogue internal terminals. There are different methods for transmitting the data. An alerting signal is needed to detect CLIPs. The parameter value depends on the analogue terminals connected. No alerting signal: Data transmission takes place between the first and second ring signal. The first ring signal is used as an alerting signal. Ring pulse: Data transmission takes place before the first ring signal. A ring pulse is used as an alerting signal. Not defined: No data is transmitted.

## Loop break signalling exchange

The following parameters apply to the signalling of the communication server with analogue network interfaces with regard to the exchange. The values differ from one country to the next. The defaults for the parameters depend on the sales channel.

Table 3. Loop break signalling exchange settings
Parameter | Explanation
Flash (ms) | Time in milliseconds for the way in which a flash signal (alerting signal) is signalled to the exchange.
Ratio | Selecting the ratio. This parameter is significant only for analogue exchange connections using pulse dialling.
Interdigit time | Interdigit time in milliseconds. This parameter is significant only for analogue exchange connections using pulse dialling.

## Collect calls

Settings for collect calls are available only for the Brazil sales channel.

Collect calls via the analogue public exchange are allowed with the double answer method: The call is answered, interrupted (loop break) and again answered.

Table 4. Collect call settings
Parameter | Explanation
Loop break | The loop break lasts only milliseconds.
Pause | The time period between the first seizing of the line and the loop break.
