Imports and exports
While importing data to the PBX is necessary to pay attention to format of imported data, especially to phone number and items od date type.
At phone numbers we emphatically recommend that column with phone number will be ALWAYS text type. If the column will not be text type, it can not be guaranteed the correct form of phone numbers, especially when phone numbers start with 0.
Formatting of blank columns
If imported file contains blank columns, it might happen that these blank columns would be indicated as errors.
