Thanks to WuBook you can receive the notifications of reservations and deletions through sms and/or fax line.
In order to configure the plugin you need only to put your fax and/or sms number.
The plugin has a cost on demand: it means that this cost is deducted from the coins credit at each use.
Sometimes the fax does not arrive and generally it depends from the fax line.
If the number corresponds to a voice + fax line and if the number is utilised as a voice line at the moment of transmission, the operation will not be successful.
After three attempts the system will not send the fax again given that it is set up to send a same fax for a maximum of 3 times.
