Number Conversion Rules

Number Conversion Rules

The number conversion rules are used to convert incoming or outgoing telephone numbers to a predefined format. In this way, the telephone numbers can be adapted to meet the local and technical requirements of the telephony server. Only then can incoming or outgoing calls be delivered in the R/3 System.

Use

These rules are:

Defined in Customizing for the calling number in the case of incoming calls.

Specified when creating or changing the telephony server for the dialed number in the case of outgoing calls.

Structure

The number conversion rules comprise the following inputs:

Replaced number
Replacement number
Note

If the server does support numbers in canonical format (e.g. +49 (271) 324), you must only define number conversion rules which apply to internal numbers for outgoing calls.

If the server does not support numbers in canonical format (e.g. 12378456), you must define number conversion rules which apply to internal, local, national, and international numbers for outgoing calls.
Example

Number conversion rules for outgoing calls

For a server that supports numbers in canonical format in the USA with the prefix 708/47:

Replaced number	Replacement number	Note
+1 (708) 47		Internal calls

For a server that does not support numbers in canonical format in Germany with the prefix 06227/12:

Replaced number	Replacement number	Note
0622712		Internal calls
06227	0	Local call with digit inserted for obtaining external line (digit 0)
00	900	International call with international prefix 00 and digit inserted for obtaining international connection (digit 9)
0	00	National call with national prefix 0 and digit inserted for obtaining external line (digit 0)

If the number for obtaining an outside line is identical for long-distance and international calls (for example, 0), one number conversion rule is sufficient for both.
