Number Conversion Rules

Use

The telephone numbers that a user or an application transfers to SAPphone or expects from SAPphone cannot always be transferred to the telephone system unchanged. For example, the telephone number of an internal user is transferred from the address management complete with area code and general prefix, but the telephone only expects the extension.

Conversely, inbound telephone numbers from the telephone system are not always transferred to SAPphone in the form it requires to find the corresponding work center. To find the work center, SAPphone requires either the extension (if the server name is specified directly) or number prefix and extension (if the telephony server has to be determined using the number prefix of the site).

• You can define number conversion rules for the necessary changes. The telephone numbers can then be adjusted to the local and technical requirements of the telephony system.

The number conversion rules comprise the following specifications:

• Replaced number

• Replacement number

• Note

For example, if you specify 0 as the replaced number and 00 as the replacement number, the number 06227/747 is changed to 006227/747.

Activities

You create the rules for inbound and outbound calls separately: In the case of inbound calls, the called numbers are defined in Customizing, whereas in the case of outbound calls, the dialed numbers are defined when the telephony server is created or changed. Note the following regarding the rules for outbound calls:

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

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