Why cannot the phone switch to PSTN by pressing '*00'?

Date: 2008-3-22   Hits: 101

1) Open the setting page and change the PSTN Access Code into '*00'


2) Check the other parameters and change the parameter starting with '*' into other number.


3) Save, reboot and try again. If it doesn't work still, restore the factory default setting and try again.
