Using behind PABX: External call forwarding with pause

Depending in the configuration of a PABX it can be necessary to dial a predial number, to access the line. Some older PABX models need a pause (P) to seperate the predial from the number you want to call to.

This function is not supported by the Gigaset HC450, so it is not possible to use the external call forwarding with such older PABX.
