8.4. Normalisation
Work with normalisation table is described in chapter 7.5. The
table normalises the calling (CLIP) numbers of the incoming calls
from GSM network.
The normalisation should be made to display the calling number
on the IP telephone in such manner, which enables proper routing
of the back call into the 2N VoiceBlue Enterprise gateway.
If e.g. the gateway is configured to dial the calls into the GSM
network by means of prefix 0 and the incoming CLIP from GSM
network starts with +420, the prefix +420 must be detached and
replaced by 0 (see fig. 55).
